Illustratively, the data verification device may specifically be a base station.
In some embodiments, the control platform 12 may be a data verification device configured to perform the data verification method provided by the embodiments of the present application as shown in fig. 9. The control platform 12 can perform the following steps in the data verification method: as in step S201, step S206, step S209 to step S211 in the data verification method shown in fig. 2, all of steps S301 to S305 shown in fig. 3, and step S501 shown in fig. 5. Illustratively, the data verification device can be a management layer software integration system for realizing different function control requirements.

For example, the data verification apparatus may specifically be a device that is set up by multiple operators together and can be responsible for data block generation and data block storage.
Fig. 2 is a flowchart of a data verification method according to an embodiment of the present application, which is specifically an interaction process diagram of an anchor cell and a control platform, where steps performed by the anchor cell in the flowchart may be performed by any anchor cell. As shown in fig. 2, the data verification method may include:
s201, the control platform sends an auxiliary node group request to the anchor cell.
S202, the anchor point cell receives an auxiliary node group request sent by the control platform, wherein the auxiliary node group request comprises a candidate auxiliary node group corresponding to the anchor point cell.
The secondary node group request may include a secondary node group list, where the secondary node group list includes a plurality of candidate secondary node groups with a secondary node group weight value in a leading bit order.
And the control platform selects a plurality of candidate auxiliary node groups with the bit sequences of the auxiliary node group weight values close to the former from all the candidate auxiliary node groups, and takes the selected candidate auxiliary node groups as the candidate auxiliary node groups of the auxiliary node group list.
Illustratively, there are K candidate auxiliary node groups in the auxiliary node group list in the auxiliary node group request, and a terminal auxiliary node in each candidate auxiliary node group corresponds to the same anchor cell. That is, K anchor cells correspond one-to-one to K candidate secondary node groups. And the control platform respectively sends an auxiliary node group request to K anchor point cells corresponding to the K candidate auxiliary node groups.
And the control platform selects the auxiliary nodes of the terminal by taking the auxiliary node group as a unit. For example, each secondary node group includes ni terminal secondary nodes, and the ni terminal secondary nodes belong to the same cell, which is referred to as an anchor cell corresponding to the ni terminal secondary nodes.
As a possible implementation manner, the control platform identifies the secondary Node Group through an auxiliary Node Group IDentity (ANG-ID). When the terminal auxiliary node moves, that is, the position changes, the auxiliary node group list also needs to update the auxiliary node group in real time according to the moving position condition of the terminal auxiliary node. Wherein each secondary node group contains the following information: the auxiliary node group identifier, the anchor cell identifier, the contractor identifier and the auxiliary node group list information. The contractor identifier is used to characterize the contractor of the anchor cell base station, for example, in AB co-construction sharing, the contractor identifier a is 00, and the contractor base station identifier B is 01.
S203, the anchor point cell responds to the auxiliary node group request, and whether the candidate auxiliary node group has the confirmation consensus capacity or not is determined by confirming whether the number of the terminal auxiliary nodes with the data verification qualification in the candidate auxiliary node group meets the preset number or not.
It should be noted that, in response to the secondary node group request, the anchor cell determines whether the candidate secondary node group has the confirmation consensus capability by determining the number of terminal secondary nodes qualified for data verification in the candidate secondary node group. Specifically, the process of performing step S203 described above may be implemented by steps S301 to S305 as shown in fig. 3.
And S204, if the anchor point cell confirms that the number of the terminal auxiliary nodes with data verification qualification in the candidate auxiliary node group meets the preset number, sending auxiliary node group confirmation information to the control platform, wherein the auxiliary node group confirmation information is used for representing that the candidate auxiliary node group has the confirmation consensus capability.
And the anchor point cell sends auxiliary node group confirmation information to the control platform under the condition of determining that the candidate auxiliary node group has the confirmation consensus capability so as to represent that the candidate auxiliary node group contained in the auxiliary node group request sent by the control platform has the confirmation consensus capability.
S205, the control platform receives the auxiliary node group confirmation information sent by the anchor point cell, and determines the candidate auxiliary node group corresponding to the auxiliary node group confirmation information in the auxiliary node group list as the auxiliary node group.
It should be noted that, after receiving the auxiliary node group confirmation information sent by the anchor cell, the control platform determines, by the anchor cell, a candidate auxiliary node group with a confirmation consensus capability and an anchor cell corresponding to the candidate auxiliary node group, and continues to store the candidate auxiliary node group and the anchor cell in the auxiliary node group list, that is, determines the candidate auxiliary node group as the auxiliary node group.
And S206, if the anchor point cell confirms that the number of the terminal auxiliary nodes with data verification qualification in the candidate auxiliary node group does not meet the preset number, sending auxiliary node group rejection information to the control platform, wherein the auxiliary node group rejection information is used for representing that the candidate auxiliary node group does not have the confirmation consensus capability.
It should be noted that, the anchor cell determines whether each candidate secondary node group has the capability of confirming the consensus according to the number of terminal secondary nodes with data verification qualification included in the candidate secondary node group. In detail, if the number of terminal secondary nodes qualified for data verification is less than the preset number, it is determined that the candidate secondary node group does not have the confirmation consensus capability, and if the number of terminal secondary nodes qualified for data verification is greater than or equal to the preset number, it is determined that the candidate secondary node group has the confirmation consensus capability. Further, when the anchor cell determines that the candidate secondary node group does not have the confirmation consensus capability, secondary node group rejection information is sent to the control platform to indicate that the candidate secondary node group included in the secondary node group request sent by the control platform does not have the confirmation consensus capability.
And S207, the control platform receives the auxiliary node group rejection information sent by the anchor point cell.
And S208, the control platform updates and replaces the auxiliary node group corresponding to the auxiliary node group rejection information and the corresponding anchor point cell in the auxiliary node group list according to the candidate auxiliary node group with the most advanced weight value bit sequence of other auxiliary node groups except the auxiliary node group list.
It should be noted that, after receiving the auxiliary node group rejection information sent by the anchor cell, the control platform determines, by the anchor cell, an auxiliary node group that does not have a capacity of determining consensus and an anchor cell corresponding to the auxiliary node group, deletes the auxiliary node group from the auxiliary node group list, and determines, as a candidate auxiliary node group in the auxiliary node group list, a candidate auxiliary node group whose weight value bit order is the most advanced in other auxiliary node groups other than the auxiliary node group list.
The auxiliary node group list is determined by the control platform according to the auxiliary node group weight value. Specifically, K candidate auxiliary node groups with higher bit sequences of the auxiliary node group weight values in all the candidate auxiliary nodes are selected as the candidate auxiliary node groups in the auxiliary node group list.
For example, step S208 is described in detail by taking the example that the secondary node group list includes K candidate secondary node groups. The auxiliary node group list includes K candidate auxiliary node groups, and it can be understood that before the verification of the confirmation consensus ability of the K candidate auxiliary node groups corresponding to the K anchor cells, the auxiliary node group list includes K candidate auxiliary node groups, where the K candidate auxiliary node groups are K candidate auxiliary node groups whose weighted values have a higher order. If 1 auxiliary node group rejection information is received after the K candidate auxiliary node groups corresponding to the K anchor cells are verified by the confirmation consensus capacity, the control platform updates the candidate auxiliary node group corresponding to the auxiliary node group rejection information in the auxiliary node group list to the (K +1) th candidate auxiliary node group with the candidate auxiliary node group weight bit sequence located at (K +1), deletes the candidate auxiliary node group corresponding to the auxiliary node group rejection information from the auxiliary node group list, and renews the bit sequences of all candidate auxiliary node group weights.
As one possible implementation, the secondary node group weight value is determined by equation (1) in the following manner:
wgi ═ Wn × Ln + Wo × Lo + Ws × Ls ] × Io, formula (1)
Wgi represents an auxiliary node group weight value, Wn represents a terminal auxiliary node weight, Ln represents a terminal auxiliary node number grade, Wo represents an anchor point cell resource occupancy rate weight, Lo represents an anchor point cell idle time occupancy rate grade, Ws represents a terminal auxiliary node serving as a weight, Ls represents a terminal auxiliary node historical occupation condition grade, Io represents an anchor point cell resource occupancy rate indication, Wn, Ln, Wo, Lo, Ls and Io are all larger than or equal to 0, and Ws is an integer larger than or equal to 1.
As a possible implementation manner in the above embodiment, Ln is related to the number ni of terminal secondary nodes. And if the number ni of the terminal auxiliary nodes is in different intervals, the Ln values are different. The larger the number of terminal slave nodes (i.e., ni) included in the slave node group, the larger Ln, e.g., ni < 50, Ln ≧ 0, 50 ≦ ni < 100, Ln ≦ 1, 100 ≦ ni < 150, Ln ≦ 2, ni ≧ 150, and Ln ≦ 3.
In detail, Lo is an idle occupancy rate level of the anchor cell, and it can be understood that the division is performed according to the idle resource occupancy rate of the anchor cell, and the resource occupancy rates of the anchor cell are different in Lo values in different intervals. And in the interval with the highest resource occupancy rate, Lo is 0. For example, the idle occupancy rate of the anchor cell is greater than 70%, L0 is 0, the idle occupancy rate level of the anchor cell is 50% to 70%, Lo is 1, the idle occupancy rate level of the anchor cell is less than 50%, and Lo is 2.
Where the initial value of Ls is 0, and Io represents the anchor cell resource occupancy indication, it can be understood that Io is 0 when Lo is equal to 0, and Io is 1 when Lo is not equal to 0. The purpose of the Io value is to temporarily not select the anchor cell as the secondary node group when the anchor cell load is high, so as not to further increase the anchor cell load.
Further, WS is greater than (Wn × Lnmax + Wo × Lomax), and Lnmax and Lomax are maximum values that Ln and Lo can take.
Further, when Ln, Lo, or Ls changes, the value of Wgi also changes. Wherein, Ln and Lo are sent to the control platform by the anchor cell, and the anchor cell will periodically update the values of Ln and Lo.
It should be noted that, in the present application, the control platform may also process the received secondary node group acknowledgement information or the secondary node group rejection information one by one as in the above embodiments, or may process all the secondary node group acknowledgement information or the secondary node group rejection information at the same time.
Illustratively, after verifying the confirmation common-identification capability of the K candidate auxiliary node groups, if (K-n) auxiliary node group confirmation information and n auxiliary node group rejection information are received, updating the n candidate auxiliary node groups corresponding to the auxiliary node group rejection information to the (K + n) th candidate auxiliary node group with the candidate auxiliary node group weight bit order located at (K + n), deleting the n candidate auxiliary node groups corresponding to the n auxiliary node group rejection information from the auxiliary node group list, and updating the bit orders of all candidate auxiliary node group weights. The sequence and the number of the auxiliary node group confirmation information or the auxiliary node group rejection information processed by the control platform at the same time are not limited.
It can be understood that, after one or more candidate auxiliary node groups corresponding to the auxiliary node group list are updated, if a candidate auxiliary node group corresponding to the auxiliary node group list needs to be deleted or added, one or more candidate auxiliary node groups and corresponding anchor cells included in the auxiliary node group list included in the auxiliary node group request are all updated, and the updated auxiliary node group request is sent to the updated anchor cells to determine the confirmation and consensus capabilities of the updated candidate auxiliary node groups.
As can be seen from the foregoing embodiments, in the data verification method provided in the embodiments of the present application, the control platform determines a plurality of candidate auxiliary node groups through the bit sequences of the auxiliary node group weight values. And the candidate auxiliary node groups respectively correspond to one anchor point cell one by one. And each anchor point cell respectively confirms the confirmation common identification capability of the corresponding candidate auxiliary node group so as to determine the auxiliary node group. Therefore, the auxiliary node group and the terminal auxiliary node corresponding to the anchor point cell determined by the data verification method ensure the confirmation consensus ability of the auxiliary node group participating in the data verification consensus, that is, ensure that the anchor point cell corresponding to the auxiliary node group can contain enough terminal auxiliary nodes with data verification qualification, thereby ensuring the reliability in the data verification process.
Fig. 3 is a flowchart of a data verification method according to an embodiment of the present application, and as shown in fig. 3, the data verification method is executed by an anchor cell, and specifically may include:
s301, determining N terminal auxiliary nodes with the terminal auxiliary node weight bit sequences in front from M terminal auxiliary nodes included in the candidate auxiliary node group.
S302, terminal auxiliary node requests are sent to the N terminal auxiliary nodes, and the terminal auxiliary nodes are confirmed to have data verification qualification according to the confirmation result whether the terminal auxiliary nodes return within the preset time. The terminal auxiliary node request is generated by the anchor point cell according to an auxiliary node group request sent by the control platform, and the terminal auxiliary node request further comprises a preset wireless signal quality parameter, and the preset wireless signal quality parameter is used for testing whether the terminal auxiliary node has data verification capability. Specifically, the description that the preset wireless signal quality parameter is used for testing whether the terminal auxiliary node has the data verification capability is described in detail in the following description of the specific implementation of step S402.
It should be noted that when the preset number is N, after acquiring the terminal auxiliary node weights of all terminal auxiliary nodes in the candidate auxiliary node group, the anchor point cell determines N terminal auxiliary nodes with the terminal auxiliary node weights before the bit order from all terminal auxiliary nodes (i.e., M terminal auxiliary nodes). And then sending the terminal auxiliary node request to the N terminal auxiliary nodes so that the N terminal auxiliary nodes respectively determine the data verification qualification of the respective terminal auxiliary node.
The preset number N can be set according to the requirement. In any implementation, when the number M of terminal auxiliary nodes included in the candidate auxiliary node group is determined to be less than N, the auxiliary node group rejection information is sent to the control platform.
As a possible implementation manner, the preset number N of terminal auxiliary nodes may be understood as N of terminal auxiliary nodes actually assuming the functions of the auxiliary nodes each time. N is obtained according to the following formula:
n ═ rounding up (b/K) + M0, equation (2)
Wherein, b is the total number of the auxiliary nodes required by the data verification consensus for each time, K is the number of the auxiliary node groups required by the data verification consensus for each time, and M0 is the required terminal auxiliary node margin. The preset number N acquired by the method can prevent the auxiliary node of the terminal from moving to other anchor point cells and being incapable of directly establishing connection with the anchor point cells in the data verification consensus process.
S303b, if it is confirmed that N1 terminal secondary nodes qualify for data verification and N1 is equal to N, determining that the candidate secondary node group has the confirmation consensus capability.
It should be noted that, if the anchor point cell receives the confirmation results returned by the N terminal auxiliary nodes within the preset time, it indicates that the candidate auxiliary node group has the confirmation consensus capability, that is, the anchor point cell may send the auxiliary node group confirmation information to the control platform. If the anchor point cell does not receive the confirmation results returned by the N terminal auxiliary nodes within the preset time, the candidate auxiliary node group does not have the confirmation consensus capability, namely the anchor point cell can send auxiliary node group rejection information to the control platform.
S303a, if it is confirmed that N1 terminal auxiliary nodes have data verification qualification and N1 is smaller than N, judging whether the current request times are smaller than the preset times.
The number of requests is the number of times of sending terminal auxiliary node requests to a plurality of terminal auxiliary nodes at the same time.
S304, if the current request times are less than the preset times, determining (N-N1) terminal auxiliary nodes with the terminal auxiliary node weight at the front position from the terminal nodes of the candidate auxiliary node group except the N terminal auxiliary nodes, and sending terminal auxiliary node requests to the (N-N1) terminal auxiliary nodes.
And S305, updating N1 according to the number of terminal auxiliary nodes qualified for data verification in the (N-N1) terminal auxiliary nodes until the request number is equal to the preset number, or N1 is equal to N, or terminal auxiliary node requests are sent to all the terminal auxiliary nodes.
It should be noted that, when the number of the confirmation results returned by the terminal auxiliary node received in the preset time by the anchor point cell is smaller than the preset number N, the total number of times that the current anchor point cell sends the terminal auxiliary node requests to the plurality of terminal auxiliary nodes is counted, and whether the total number of times (that is, the current request) reaches the preset number is determined. If the current request times are larger than or equal to the preset times, the candidate auxiliary node group does not have the capacity of confirming the consensus, namely the anchor point cell can send auxiliary node group rejection information to the control platform.
Specifically, if the current request times are less than the preset times and (N-N1) terminal auxiliary nodes with the terminal auxiliary node weight bit sequence being earlier can be selected from the terminal nodes of the candidate auxiliary node group except the N terminal auxiliary nodes, the terminal auxiliary node request is sent to the (N-N1) terminal auxiliary nodes, and simultaneously the N1 and the update request times are updated according to the number of the terminal auxiliary nodes with data verification qualification in the (N-N1) terminal auxiliary nodes. And the updated N1 and N, the updated request times and the preset times are judged.
Specifically, if the current request frequency is less than the preset frequency and the terminal nodes of the candidate auxiliary node group other than the N terminal auxiliary nodes cannot be selected from the terminal nodes with the terminal auxiliary node weight bit sequence earlier (N-N1), it indicates that the candidate auxiliary node group does not have the confirmation consensus capability, that is, the anchor cell may send the auxiliary node group rejection information to the control platform.
Wherein, according to the number of terminal secondary nodes having data verification qualification among the (N-N1) terminal secondary nodes, updating the N1 may be understood as updating the N1 to (N1+ b) if the number of terminal secondary nodes having data verification qualification among the (N-N1) terminal secondary nodes is b.
Illustratively, if the anchor cell receives N confirmation results returned by N terminal auxiliary nodes in the candidate auxiliary nodes within the preset time Taw1, it replies the auxiliary node group confirmation information to the control platform to confirm that the N terminal auxiliary nodes of the candidate auxiliary node group serve as the terminal auxiliary node function in the data verification consensus.
If the anchor cell only receives the confirmation messages of N1 auxiliary nodes (N1 < N) in Taw1, the terminal auxiliary nodes replying the rejection result and the terminal auxiliary nodes without any reply in the N terminal auxiliary nodes of the anchor cell are abandoned, namely the anchor cell can not act as the terminal auxiliary node (even if the subsequent process receives the confirmation messages of the auxiliary nodes sent by the terminal, the process is abandoned). The terminal-subsidiary node cancellation message may be sent to the terminal-subsidiary node that gave up processing.
Meanwhile, the anchor cell selects (N-N1) terminal auxiliary nodes with the front terminal auxiliary node weight bit sequence according to the terminal auxiliary node weight Wui, sends terminal auxiliary node requests to (N-N1) terminal auxiliary nodes, adds 1 to a counter Ci1, waits for Taw1 to collect reply messages of (N-N1) terminal auxiliary nodes, repeats the step of sending the terminal auxiliary node requests to the (N-N1) terminal auxiliary nodes and the determination steps after the step if the (N-N1) auxiliary node confirmation messages are not collected, namely the total number of the received auxiliary node confirmation messages does not reach N, continues to search for alternative terminal auxiliary nodes according to the terminal auxiliary node weight Wui, and adds 1 to the counter round number Ci1 until N auxiliary nodes are found, and replies auxiliary node group confirmation messages to the control platform. Wherein Ci1 is the round number of the terminal auxiliary node search counter of the anchor cell, the initial value is 0, and Ci1 can be understood as the round number for recording the terminal auxiliary node search of the anchor cell.
Further, if the value of Ci1 reaches the preset number of times, N auxiliary node terminals are not found yet, or the anchor point cell has issued terminal auxiliary node requests to all terminal auxiliary nodes of the candidate auxiliary node group but has not received the confirmation information of N auxiliary nodes, or the number of terminal auxiliary nodes in the auxiliary node group list under the candidate auxiliary node group is less than N, the anchor point cell corresponding to the candidate auxiliary node group sends auxiliary node group rejection information to the control platform.
Further, when the control platform receives the auxiliary node group rejection message sent by the auxiliary node anchor cell, the control platform sends auxiliary node group rejection information to the candidate auxiliary node group, reselects the candidate auxiliary node group according to the auxiliary node group weight value Wgi, and sends an auxiliary node group request message to the updated candidate auxiliary node group.
Further, the control platform receives the auxiliary node group confirmation information sent by all the candidate auxiliary node groups, and takes all the candidate auxiliary node groups corresponding to the auxiliary node group confirmation information as all the auxiliary node groups, thereby completing the selection of the auxiliary node groups and the auxiliary of the terminal auxiliary node.
Further, the control platform sends the determined auxiliary node group to anchor cells corresponding to all auxiliary node groups in the auxiliary node group list. The auxiliary node group list comprises auxiliary node group identifications and anchor point cell identifications of all auxiliary node groups participating in data verification consensus work at this time.
Fig. 4 is a flowchart of a data verification method according to an exemplary embodiment of the present application, which is specifically a schematic diagram of an interaction process between an anchor cell and a terminal secondary node, and as shown in fig. 4, the data verification method may include:
s401, the anchor point cell sends terminal auxiliary node requests to the N terminal auxiliary nodes.
S402, the terminal auxiliary node determines whether the terminal auxiliary node has data verification qualification.
And S403, the terminal auxiliary node sends a confirmation result of data verification qualification determination of the terminal auxiliary node to the anchor point cell.
S404, the anchor point cell confirms whether the terminal auxiliary node has data verification qualification according to the confirmation result whether the terminal auxiliary node returns in the preset time.
The terminal auxiliary node request comprises a preset wireless signal quality parameter, and the preset wireless signal quality parameter is used for testing whether the terminal auxiliary node has data verification capability.
As can be seen from the foregoing embodiments, in the embodiments of the present application, the anchor cell and the terminal auxiliary node in the data verification method in steps S302 to S304 perform a specific interaction process. With reference to fig. 3 and 4, in the embodiment of the present application, whether N terminal auxiliary nodes having data verification qualification in a candidate auxiliary node group are determined by a manner that an anchor point cell and a terminal auxiliary node interact with each other through a terminal auxiliary node request and a confirmation result, so as to determine whether the candidate auxiliary node group has a confirmation consensus capability.
Specifically, the anchor cell summarizes the sending of the confirmation results sent by the terminal auxiliary node, and determines the quantity of the summarized confirmation results. And when the number of the determined results is less than the preset number N, the anchor point cell determines the number of the terminal auxiliary nodes and the number of the terminal auxiliary nodes which send the terminal auxiliary node request again according to the auxiliary node weights of the remaining terminal auxiliary nodes. If the number of the confirmation results does not reach N, the processes of judging the number of the confirmation results, the number of the requests and sending the terminal auxiliary node requests are carried out until the number of the requests is equal to the preset number, or the number of the summarized confirmation results is equal to N, or the terminal auxiliary node requests are sent to all the terminal auxiliary nodes.
As a possible implementation manner, the step S402 can be implemented in the following manner. The preset wireless signal quality parameter is set as a preset signal receiving power and a preset signal-to-interference-plus-noise ratio, wherein the preset signal-to-interference-plus-noise ratio refers to a ratio of a pre-stored received useful signal strength to a received interference signal (noise and interference) strength. And under the condition that any one terminal auxiliary node judges that the reference signal receiving power corresponding to any one terminal auxiliary node is greater than or equal to the preset signal receiving power and the signal-to-interference-plus-noise ratio corresponding to any one terminal auxiliary node is greater than or equal to the preset signal-to-interference-plus-noise ratio, the terminal auxiliary node sends a confirmation result to the anchor point cell. And under the condition that any one terminal auxiliary node judges that the reference signal receiving power corresponding to any one terminal auxiliary node is smaller than the preset signal receiving power or the signal-to-interference-plus-noise ratio corresponding to any one terminal auxiliary node is smaller than the preset signal-to-interference-plus-noise ratio, the terminal auxiliary node does not send a rejection message to the anchor point cell.
It should be noted that, the terminal auxiliary node does not send the rejection message to the anchor cell, and it can be understood that neither the confirmation result nor the rejection result is sent to the anchor cell.
Fig. 5 is a flowchart of a data verification method according to an exemplary embodiment of the present application, which is specifically an interaction process diagram of a control platform, an anchor cell, a terminal secondary node, and a primary node, and as shown in fig. 5, the data verification method may include:
s501, the control platform sends a data verification request to the anchor point cell and the main node.
The data verification request may be a data verification request generated by the control platform according to the data to be verified. The data to be verified can be network quality data formed by summarizing measurement reports in a certain time period by the control platform.
Illustratively, the data validation request may be formed based on the network quality data and recorded timestamp data associated with the network quality data.
And S502, the main node receives the data verification request sent by the control platform, and verifies the data to be verified to generate a third verification result.
And S503, the main node generates a third verification confirmation request according to the third verification result.
It should be noted that the control platform sends all the master nodes to the data verification request, so that all the master nodes verify the data to be verified. The data verification request comprises data to be verified.
As one possible manner, step S502 and step S503 may be implemented by the following detailed manner. And the master node performs data verification and block packaging on the information in the data verification request, and generates a third verification confirmation request for the block data, the block abstract, the timestamp, the block serial number and the block information after the block packaging and verification.
In some embodiments, the third authentication confirmation request is cryptographically processed before it is sent.
S504, the first anchor point cell receives a data verification request sent by the control platform.
The first anchor point cell is an anchor point cell corresponding to any one auxiliary node group.
And S505, the first anchor point cell sends the data verification request to the terminal auxiliary node corresponding to the first anchor point cell.
It can be understood that the control platform does not directly send the data verification request to the terminal auxiliary node, but forwards the data verification request to the terminal auxiliary node corresponding to the first anchor point cell through the first anchor point cell, thereby reducing the number of times that the control platform sends the data to be verified.
S506, the terminal auxiliary node receives the data verification request sent by the first anchor point cell.
And S507, the terminal auxiliary node verifies the data to be verified in the data verification request to generate a first verification result.
And S508, the terminal auxiliary node sends the first verification result to the first anchor point cell.
S509, the first anchor cell receives a first verification result returned by the terminal auxiliary node corresponding to the first anchor cell, so as to determine a first verification confirmation request.
It can be understood that, each anchor point cell collects the verification results returned by all the terminal auxiliary nodes corresponding to each anchor point cell to obtain the first verification confirmation request. Illustratively, when one first anchor point cell includes N terminal auxiliary nodes, after the N terminal auxiliary nodes verify data to be verified respectively, the N terminal auxiliary nodes send respective verification results to the corresponding first anchor point cell, and the first anchor point cell aggregates the N verification results returned by the N terminal auxiliary nodes to obtain a first verification confirmation request. The first authentication confirmation request includes a first authentication result.
In some embodiments, the first verification result includes block data, a block digest, a timestamp, a block sequence number, and block information formed after the terminal secondary node packs and verifies the data block.
Optionally, the first verification result may include encrypted information of the first verification result.
And S510, the first anchor point cell sends the first verification confirmation request to the terminal auxiliary node corresponding to the first anchor point cell.
S511, the first anchor point cell sends the first verification confirmation request to the master node.
S512, the main node confirms the consensus of the first verification result in the first verification confirmation request.
S513, the terminal secondary node confirms the consensus on the first verification result in the first verification confirmation request.
It can be understood that the first anchor point cell obtains the first verification confirmation request according to the verification results of all terminal auxiliary nodes corresponding to the first anchor point cell. And sending the first verification confirmation request to the main node and the terminal auxiliary node to complete confirmation and consensus of the main node and the terminal auxiliary node on the first verification result.
It should be noted that, data transmission between terminal auxiliary nodes corresponding to each anchor point cell is also forwarded through the anchor point cell. In detail, the first anchor point cell sends the first verification confirmation request to the second anchor point cell, all the main nodes and the terminal auxiliary nodes corresponding to the first anchor point cell, so that all the terminal auxiliary nodes and all the main nodes confirm the first verification result in a common way, wherein the first anchor point cell is an anchor point cell corresponding to any one auxiliary node group, and the second anchor point cell is any anchor point cell except the first anchor point cell. The first anchor point cell receives a second verification confirmation request sent by a second anchor point cell, wherein the second verification confirmation request comprises a second verification result of the terminal auxiliary node corresponding to the second anchor point cell on the data to be verified; and the first anchor point cell sends a second verification confirmation request to the terminal auxiliary node corresponding to the first anchor point cell so that the terminal auxiliary node corresponding to the first anchor point cell confirms the consensus on the second verification result.
S514, the master node sends the third verification confirmation request to the first anchor cell.
It should be noted that the master node further sends a third verification confirmation request to the second anchor point cell, so that the terminal secondary node corresponding to the second anchor point cell confirms consensus for the third verification result in the third verification confirmation request. In other words, the master node sends the third verification confirmation request to all anchor point cells, which are the first anchor point cell and the second anchor point cell.
S515, the first anchor point cell receives the third verification confirmation request sent by the master node.
And S516, the first anchor point cell sends the third verification confirmation request to the terminal auxiliary node corresponding to the first anchor point cell.
And S517, the terminal auxiliary node confirms the consensus on the third verification result in the third verification confirmation request.
The master node may send the third verification confirmation request to all anchor cells participating in data verification, that is, the first anchor cell and the second anchor cell.
It should be noted that the master node reduces the number of times that the master node transmits data by sending a third verification confirmation request to the anchor cell.
When the number of the master nodes is multiple, the master node forwards the third verification confirmation request of the master node to other master nodes, so that the other master nodes can confirm and agree on the third verification result in the third verification confirmation request.
As shown in fig. 6 and 7, for example. Fig. 6 is a diagram illustrating a data link between nodes in the related art. Fig. 7 is a schematic diagram of data links between nodes according to an embodiment of the present application. Take 2 primary nodes and 6 terminal secondary nodes in both fig. 6 and fig. 7 as an example. In fig. 6, the primary node is Z1 'and Z2', and the terminal secondary nodes are F1 ', F2', F3 ', F4', F5 'and F6'. In fig. 7, the primary nodes are Z1 and Z2, the terminal secondary nodes are F1, F2, F3, F4, F5 and F6, and anchor cells M1 and M2. In the data verification consensus process, when the verification result of the master node Z1 ' is confirmed and consensus is performed in the related art, a verification confirmation request needs to be sent to each auxiliary node and each master node, that is, 7 times, and similarly, the verification result confirmation requests sent by each node Z1 ', Z2 ', F1 ', F2 ', F3 ', F4 ', F5 ' and F6 ' in the data verification consensus process are all 7 times, so that the confirmation consensus process of the verification results of all the other nodes on the node can be completed. In the embodiment of the present application, the master nodes Z1 and Z2 can all complete the confirmation and consensus of the verification result of the master node by the remaining nodes by only sending verification confirmation requests 3 times. In the embodiment of the present application, the auxiliary nodes F1, F2, F3, F4, F5, and F6 all can complete the confirmation consensus of the verification result of the node by all other nodes (all nodes except the node) by sending the verification confirmation request only once. Therefore, the data verification method provided by the application can reduce the communication times of receiving and sending data between each auxiliary node and the main node in the data verification consensus process, and reduce the complexity of the data verification consensus process, thereby reducing the power consumption of the terminal and the time delay of the data consensus process.
It should be noted that, in this embodiment, the anchor cell and the terminal secondary node corresponding to the anchor cell may be obtained through steps S201 to S208 and/or steps S301 to S305 and/or steps S401 to S404 in the provided data verification method. Further ensuring that the anchor point cell participating in data verification has the capability of confirming consensus and the terminal auxiliary node corresponding to the anchor point cell has the capability of data verification.
In some embodiments, the primary node is set up by an operator together and is responsible for block generation and block storage devices, and the terminal secondary node selects a terminal with terminal bearing capacity in the network, that is, the terminal is selected comprehensively based on factors such as terminal capacity, terminal will, terminal electric quantity and historical participation conditions. The selected terminal auxiliary node participates in the data block generation verification in the data verification process. And the quality information of the co-constructed shared network is credibly stored by matching the main node and the terminal auxiliary node.
It should be noted that, in the above embodiment, after all the primary nodes and the terminal secondary nodes generate the confirmation consensus on the verification result in the verification confirmation request, the corresponding confirmation consensus result is generated and then directly sent to the control platform. The confirmation common identification result corresponding to each node is marked as Cji, the nodes are any main node and any terminal auxiliary node, the verification confirmation request comprises a first verification confirmation request generated by the first anchor point cell according to the first verification result, a second verification confirmation request generated by the second anchor point cell according to the second verification result, and a third verification confirmation request generated by the main node according to the third verification result, and the second anchor point cell is any anchor point cell except the first anchor point cell.
In some embodiments, after performing steps S510 to S517, the control platform determines the target consensus result according to the received confirmation consensus results sent by all the terminal secondary nodes and all the primary nodes.
Illustratively, after receiving the confirmation consensus results sent by all the primary nodes and the terminal secondary nodes, the control platform generates a confirmation consensus result set { Cij } (where Cji is the confirmation consensus result of the node j to the node i, and j ≠ i) for the verification of the verification result of each node to other nodes. And the control platform determines the main node with the maximum sum of the confirmation consensus results of other nodes in the main nodes on the basis of the verification set { Cij } sent by each node, takes the verification result corresponding to the maximum main node as a target consensus result, and broadcasts the target consensus result to all the main nodes so that all the main nodes store the target consensus result. In some embodiments, the target consensus result is typically the best block data.
Through the embodiment, the control platform generates the data verification request according to the data to be verified, and then sends the generated data verification request to all anchor point cells and all main nodes. And all anchor point cells forward the received data verification request to all terminal auxiliary nodes corresponding to the respective anchor point cells. Therefore, the verification of the data to be verified of all the terminal auxiliary nodes and all the main nodes is completed. After the verification is completed, on one hand, the master nodes send verification results generated by the verification of the data to be verified to other master nodes and all anchor point cells respectively so as to complete the confirmation and the consensus of the verification results of all the master nodes and all the terminal auxiliary nodes to all the master nodes. And simultaneously, all terminal auxiliary nodes send verification results generated by verifying the data to be verified to the anchor point cells corresponding to the terminal auxiliary nodes.
