Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an object identifier resolution device of a hardware operating environment according to an embodiment of the present invention.
As shown in fig. 1, the object identifier resolution device may include: a processor 1001, such as a Central Processing Unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Wherein a communication bus 1002 is used to enable connective communication between these components. The user interface 1003 may comprise a Display screen (Display), an input unit such as keys, and the optional user interface 1003 may also comprise a standard wired interface, a wireless interface. The network interface 1004 may optionally include a standard wired interface, a wireless interface (e.g., WI-FI interface). The Memory 1005 may be a Random Access Memory (RAM) Memory or a non-volatile Memory (e.g., a magnetic disk Memory). The memory 1005 may alternatively be a storage device separate from the processor 1001.
Those skilled in the art will appreciate that the device architecture shown in fig. 1 does not constitute a definition of an object identifier resolution device, and may include more or fewer components than those shown, or some components in combination, or a different arrangement of components.
As shown in fig. 1, a memory 1005, which is a storage medium, may include therein an operating system, a network communication module, a user interface module, and an object identifier resolution program.
In the object identifier resolution device shown in fig. 1, the network interface 1004 is mainly used for connecting to an external network and performing data communication with other network devices; the user interface 1003 is mainly used for connecting to a user equipment and performing data communication with the user equipment; the apparatus of the present invention calls an object identifier resolution program stored in the memory 1005 through the processor 1001 and executes the object identifier resolution method provided by the embodiment of the present invention.
Based on the above hardware structure, an embodiment of the object identifier parsing method of the present invention is provided.
Referring to fig. 2, fig. 2 is a flowchart illustrating an object identifier parsing method according to a first embodiment of the present invention.
In a first embodiment, the object identifier resolution method includes the steps of:
step S10, parsing the object identifier OID to be identified to determine a parent node corresponding to the OID to be identified.
It should be noted that, the execution subject in this embodiment may be an object identifier Resolution device, where the object identifier Resolution device may be an ORS client, the ORS client is a client of an OID Resolution System (Resolution System), and may also be another device that can implement the same or similar functions.
It should be appreciated that the OID resolution method according to the present embodiment provides a solution to avoid the problems caused by relying on the DNS system, and the OID resolution method according to the present embodiment does not use the conventional DNS system, but instead uses the DNS authoritative domain name service based on the block chain. Because of the use of the DNS system based on the block chain technique, the OID resolution service will inherit the specifics that can be prevented from being illegally controlled due to the absence of the central part control.
It is to be understood that, after the OID to be identified is determined, the OID to be identified may be analyzed to determine the OID node corresponding to the OID to be identified, and then the parent node corresponding to the OID node is searched.
Step S20, searching for the DNS blockchain client corresponding to the parent node, and sending an inquiry request to the DNS blockchain client, so that the DNS blockchain client determines, based on the inquiry request, analysis feedback information of the OID to be identified in the DNS blockchain network.
It should be understood that each parent node may have a corresponding DNS blockchain client, and therefore, the DNS blockchain client corresponding to the parent node may be searched and send a query request to the DNS blockchain client, and after receiving the query request sent by the ORS client, the DNS blockchain client may return the analysis feedback information of the OID in the DNS blockchain network.
Step S30, receiving the analysis feedback information fed back by the DNS blockchain client, and determining an OID analysis result according to the analysis feedback information.
It can be understood that the ORS client may receive analysis feedback information fed back by the DNS blockchain client, extract an OID analysis resource corresponding to the OID to be identified from the analysis feedback information, determine service configuration information corresponding to the OID to be identified according to the OID analysis resource, and use the service configuration information as an OID analysis result.
Further, in order to make the OID analysis more specific and improve the effect of the OID analysis, before analyzing the object identifier OID to be identified to determine the parent node corresponding to the OID to be identified, the method further includes:
when the OID sent by the application program is received, taking the received OID as the OID to be identified;
correspondingly, after the OID analysis result is determined according to the analysis feedback information, the method further includes:
and sending the OID analysis result to the application program.
It should be understood that the OID may be sent by the application or the user to the ORS client, and in this embodiment, the OID is sent by the application to the ORS client as an example.
It can be understood that, when receiving the OID sent by the application, the ORS client may use the received OID as the OID to be identified, and after determining the OID analysis result of the OID to be identified, send the OID analysis result to the application.
In the embodiment, the OID to be identified is analyzed to determine a parent node corresponding to the OID to be identified; searching a DNS blockchain client corresponding to the parent node, and sending a query request to the DNS blockchain client, so that the DNS blockchain client determines analysis feedback information of the OID to be identified in a DNS blockchain network based on the query request; and receiving the analysis feedback information fed back by the DNS block chain client, and determining an OID analysis result according to the analysis feedback information. In the embodiment, a traditional DNS system is not used, but a DNS system based on a block chain technology is used, and the problems of single point failure, single point invalidation and the like do not exist when OID analysis is performed through a DNS block chain network, and the problem of data tampering caused by illegal operation of a DNS root node is also avoided, so that the accuracy of OID analysis is improved.
In an embodiment, as shown in fig. 3, a second embodiment of the object identifier parsing method according to the present invention is proposed based on the first embodiment, where the step S10 includes:
step S101, resolving the OID to be identified so as to determine an OID node corresponding to the OID to be identified.
It should be understood that, since the OID parsing method in this embodiment is based on a block chain, each OID has its corresponding node, so that the OID to be identified may be parsed to determine the OID node corresponding to the OID to be identified.
It should be noted that OID nodes in the same hierarchy form an OID analysis block chain network, and all nodes may be divided into two types: one type is a full node, stores all OID resolution resources of the current hierarchy, can directly provide the service of OID recursive resolution, and participates in block generation and verification. The other is a light node, which is accessed to the block chain network but does not store all OID analysis resources, and needs to pull resources to all nodes when needed, and the light node does not participate in block verification and generation. During OID analysis, any node in the hierarchical block chain can be selected at will to acquire analysis service.
And step S102, searching a father node to be selected corresponding to the OID node, and taking the father node to be selected as the father node corresponding to the OID to be identified.
It should be understood that, after the OID node is determined, a node in the same level as the OID node may be searched, the node in the same level as the OID node is used as a parent node to be selected, and then a node is randomly selected from the parent node to be selected as a parent node corresponding to the OID to be identified.
In a specific implementation, as shown in fig. 4, fig. 4 is a block chain diagram of an OID node.
Further, in order to accurately determine a parent node to be selected and avoid an analysis fault caused by a data error, the finding of the parent node to be selected corresponding to the OID node includes:
searching a hierarchical block chain corresponding to the OID node; and determining a parent node to be selected corresponding to the OID node according to the hierarchical block chain.
It is understood that, the OID nodes of the same hierarchy level form one OID resolution blockchain network, and there may be multiple hierarchies, and therefore, each hierarchy level has a corresponding blockchain network. After the OID node is determined, the hierarchy to which the OID node belongs can be determined, and then the blockchain network corresponding to the hierarchy is used as the hierarchical blockchain corresponding to the OID node.
In a specific implementation, for example, there are three levels, level a, level B and level C, where level a corresponds to blockchain network a, level B corresponds to blockchain network B and level C corresponds to blockchain network C. After the OID node is determined, if the OID node belongs to the level B, the block chain network B corresponding to the level B may be used as the level block chain corresponding to the OID node.
It can be understood that nodes in the hierarchical block chain may be traversed, all traversed nodes are used as parent nodes to be selected, and then one or more nodes are selected from the parent nodes to be selected as parent nodes corresponding to the OIDs to be identified.
Further, since the nodes are respectively of the full node type and the light node type, and the resources stored by the two nodes are different, in order to achieve a better resolution effect, different query strategies may be determined according to different node types, and before the searching for the DNS blockchain client corresponding to the parent node and sending a query request to the DNS blockchain client, the method further includes:
searching a node type corresponding to the father node, and judging whether the father node is a light node or not according to the node type;
correspondingly, the sending the query request to the DNS blockchain client to enable the DNS blockchain client to determine the resolution feedback information of the OID to be identified in the DNS blockchain network based on the query request includes:
and when the father node is a light node, sending the first query request to the DNS blockchain client, so that the DNS blockchain client acquires analysis feedback information of the OID to be identified in the DNS blockchain network from a DNS server based on the first query request.
It should be understood that, after determining the parent node, the node type corresponding to the parent node may be searched, and then it is determined whether the parent node is a light node according to the node type, and when the parent node is a light node, the first query request is sent to the DNS blockchain client.
It can be understood that, since the light node accesses the blockchain network but does not store all OID resolution resources, and needs to pull resources to all nodes if necessary, the DNS blockchain client may obtain resolution feedback information of the OID to be identified in the DNS blockchain network from the DNS server based on the first query request after receiving the first query request.
Further, since all the nodes store all the OID analysis resources of the current hierarchy, the manner of obtaining the analysis resources is more convenient, and therefore, it can be preferentially determined whether a parent node is a full node, and before determining whether the parent node is a light node according to the node type, the method further includes:
judging whether the father node is a full node or not according to the node type; and when the father node is not the full node, executing the step of judging whether the father node is a light node according to the node type.
It should be understood that whether the father node is a full node or not can be judged according to the node type, whether the father node is a light node or not can be further judged when the father node is not a full node, if the father node can be directly judged to be a full node, the subsequent judgment step can be omitted, and the processing efficiency can be improved.
Further, because of the difference between the full node and the light node, the query modes and the corresponding query requests for the full node and the light node are also different, where the query request includes a second query request, and after determining whether the parent node is the full node according to the node type, the method further includes:
and when the parent node is a full node, sending the second query request to the DNS blockchain client, so that the DNS blockchain client searches the analysis feedback information of the OID to be identified in the DNS blockchain network in a local database based on the second query request.
It should be noted that, in this embodiment, the query request includes a first query request and a second query request, where the first query request corresponds to the light node, and the second query request corresponds to the full node.
It will be appreciated that a second query request may be sent to the DNS blockchain client when the parent node is a full node. Since all the OID analysis resources of the current hierarchy are stored in all the nodes, the OID recursive analysis service can be directly provided, and therefore, after the DNS blockchain client receives the second query request, analysis feedback information of the OID to be identified in the DNS blockchain network can be directly searched in the local database.
In a specific implementation, as shown in fig. 5, fig. 5 shows a data transmission diagram of OID resolution.
In the embodiment, the OID to be identified is analyzed to determine the OID node corresponding to the OID to be identified; and searching a father node to be selected corresponding to the OID node, taking the father node to be selected as the father node corresponding to the OID to be identified, further acquiring the node type of the father node, and determining different query strategies according to different node types, thereby achieving better analysis effect.
In an embodiment, as shown in fig. 6, a third embodiment of the object identifier parsing method according to the present invention is proposed based on the first embodiment or the second embodiment, and in this embodiment, the description is made based on the first embodiment, and the step S30 includes:
step S301, receiving the analysis feedback information fed back by the DNS blockchain client.
It should be understood that, after determining, according to the query request, the analysis feedback information of the OID to be identified in the DNS blockchain network, the DNS blockchain client feeds back the analysis feedback information to the ORS client, so that the ORS client can receive the analysis feedback information fed back by the DNS blockchain client.
Step S302, extracting OID analysis resources corresponding to the OID to be identified from the analysis feedback information.
It can be understood that, because the analysis feedback information includes OID analysis resources, the ORS client may extract, from the analysis feedback information, OID analysis resources corresponding to the OID to be identified.
Step S303, determining service configuration information corresponding to the OID to be identified according to the OID analysis resource, and taking the service configuration information as an OID analysis result.
It can be understood that after the OID analysis resource corresponding to the OID to be identified is determined, the service configuration information corresponding to the OID to be identified may be determined according to the OID analysis team member, and since a plurality of parent nodes may exist in order to improve the accuracy of data and prevent the data of a certain node from being tampered, a plurality of service configuration information may be determined according to analysis feedback information fed back by a plurality of DNS block chain clients, and these service configuration information may be compared to determine whether they are consistent. If it is normal, these service configuration information should be consistent, and therefore, the service configuration information may be used as the OID parsing result. However, in some specific cases, for example, data in a blockchain node is tampered, and at this time, when these pieces of service configuration information are compared, an inconsistency may occur, and in this case, a higher piece of service configuration information is used as an OID analysis result.
In a specific implementation, for example, three pieces of service configuration information are determined, the three pieces of service configuration information are fed back by the DNS blockchain client corresponding to the three nodes, and the three pieces of service configuration information are compared, and if the three pieces of service configuration information are consistent, any one of the three pieces of service configuration information can be used as an OID analysis result. If the three pieces of service configuration information are not consistent, there are two pieces of information, for example, the three pieces of service configuration information are service configuration information a, service configuration information B, and service configuration information C, respectively, and if the service configuration information a is the same as the service configuration information B, the service configuration information C is different from the other two pieces of service configuration information, therefore, any one of the service configuration information a and the service configuration information B may be used as the OID analysis result.
In this embodiment, the OID analysis result is determined by obtaining the analysis resource through the blockchain, so as to achieve an effect of performing OID analysis on the OID to be identified, and since a plurality of nodes exist in the blockchain, even if one or more blockchain nodes are damaged or break down, the analysis resource can still be obtained through other nodes, so that the problem that the OID analysis cannot be performed due to single-point damage is avoided, and since the resources in the blockchain network are publicly and transparently, the information fed back by the plurality of nodes can be compared, so as to check the authenticity and accuracy of the information, and improve the accuracy and safety of the OID analysis.
Further, in addition to performing OID analysis through the blockchain network, the method may further perform various operations on service configuration information of OIDs in the blockchain network, where after receiving the analysis feedback information fed back by the DNS blockchain client and determining an OID analysis result according to the analysis feedback information, the method further includes:
when an operation instruction corresponding to the OID to be identified is received, adjusting the service configuration information according to the operation instruction to generate service configuration information to be processed; searching for a super node in the DNS blockchain network; and sending the service configuration information to be processed to the super node so that the super node writes the service configuration information to be processed into the DNS block chain network.
It should be understood that there are super nodes in the blockchain network, and all the operations of registering, modifying, deleting, etc. of OIDs depend on the super nodes in the DNS blockchain network. And writing the service configuration information of the applied OID and the OID node tree into the block chain by the super node.

determining operation information according to the operation instruction, and determining an operation type according to the operation information; and when the operation type is modification operation, adjusting the service configuration information according to the operation information.
It should be understood that after the operation instruction is determined, the operation information may be determined according to the operation instruction, and then the operation type may be determined according to the operation information, where the operation type may include a registration operation, a modification operation, a deletion operation, and the like, and when the operation type is a modification operation, the service configuration information may be adjusted according to the operation information. When the operation type is a registration operation or a deletion operation, the operation information is directly sent to the super node without adjusting the service configuration information and is processed by the super node.
Further, since there are multiple super nodes in the blockchain, and some operations only have permission to the super node, the searching for the super node in the DNS blockchain network includes:
searching block chain network information corresponding to the DNS block chain network; and extracting super node information from the block chain network information, and determining the super node according to the super node information.
It should be understood that the blockchain network information corresponding to the DNS blockchain network may be searched, and the blockchain network information is various information corresponding to the DNS blockchain network, so as to extract the super node information from the blockchain network information, and thus the super node in the DNS blockchain network may be determined according to the super node information.
