Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
Referring to fig. 1, fig. 1 is a schematic diagram of a wireless sensor network-based block chain system 100 according to an embodiment of the present disclosure.
In this embodiment, the wireless sensor network-based blockchain system 100 may include: a plurality of wireless sensor nodes 110 (which may be considered sensor layers), gateway nodes 120 (which may be considered gateway layers), and blockchain nodes 130 (which may be considered blockchain layers).
Each wireless sensor node 110 has a unique node identifier, and each wireless sensor node 110 may be configured to perform real-time monitoring to obtain monitoring data. Meanwhile, each wireless sensor node 110 may be configured to monitor (and record) transmission content of a relevant node when transmitting data, and record a node identifier and a content hash value of the relevant node. Here, the relevant nodes, i.e. other wireless sensor nodes in the vicinity of the wireless sensor node 110, can be heard by the wireless sensor node 110 when the other wireless sensor nodes in the vicinity transmit data. The wireless sensor node 110 may also be configured to report data of the wireless sensor node 110 to any gateway node 120 (the gateway node 120 that reports data is selected according to an actual situation, where any gateway node 120 is only used to indicate that the gateway node 120 is not specific when the wireless sensor node 110 reports data, and should not be considered as a limitation of the present application), and the reported data may include monitoring data and a corresponding node identifier monitored by the wireless sensor node 110, and a hash value and a corresponding node identifier of content of a monitored related node.
Each gateway node 120 may be configured to, after receiving data reported by any wireless sensor node 110, perform verification and forward the verification to the blockchain node 130.
Any one of the blockchain nodes 130 may be configured to perform consistency check on the monitoring data corresponding to the same node identifier and all content hash values (which are the content hash values corresponding to the same node identifier and are derived from different wireless sensor nodes monitoring the wireless sensor node 110 reporting the monitoring data) in each statistical period (e.g., 1 second, 3 seconds, etc.) to determine whether to record the monitoring data into the blockchain.
For example, the blockchain link point 130 may determine whether to record the monitoring data into the blockchain by:
if the monitoring data and all content hash values corresponding to the same node identifier have consistency (that is, the monitoring data reported by the wireless sensor node 110 is consistent with the content hash values recorded by other nodes based on monitoring the transmission content of the wireless sensor node 110, indicating that the monitoring data reported by the wireless sensor node 110 is the same as the transmission content monitored by other nodes), the block chain node 130 may record the monitoring data into the block chain.
If there is no consistency between the monitoring data and any content hash value corresponding to the same node identifier (if there is inconsistency between the content hash value corresponding to the node identifier and the monitoring data), the blockchain node 130 may determine whether to record the monitoring data into the blockchain based on the number of the content hash values corresponding to the monitoring data and the same node identifier, which have consistency.
Specifically, the blockchain node 130 may count a ratio of the number of consistent content hash values corresponding to the monitoring data and the same node identifier to a total amount, where the total amount includes the number of consistent content hash values corresponding to the monitoring data and the same node identifier and the number of content hash values not having the consistency. The blockchain node 130 may then determine whether the ratio reaches a set ratio (e.g., 1/3, where set ratio 1/3 is a ratio determined based on actual test radio channel attenuation and interference-induced reception errors). If the percentage reaches the set ratio, the blockchain node 130 may record the monitoring data into the blockchain; if the percentage does not reach the set percentage, the blockchain node 130 may discard the monitored data.
In order to prevent the behavior of the gateway node that maliciously tampers with the data, the gateway domain consensus may be formed in the following manner:
first, data reported by any wireless sensor node 110 may include a timestamp T, a data source node identifier Sid, a related node identifier Rid, a data source node content hash value Hi, and the like, and after receiving data reported by any wireless sensor node 110, the gateway node 120 may add a gateway identifier Gid to the reported data and forward the data to the block chain node 130, so that the data forwarded by the gateway node 120 is in the following form:
Specifically, the block link point may be the first candidate record:
Then, the block link points may be counted according to the first candidate record and the second candidate record, and a majority of the consistent results are the consensus result:
Since the wireless sensor node 110 reports data in a wireless broadcast manner, the data can be monitored by other wireless sensor nodes 110, and in addition, the data reported by the same wireless sensor node 110 can be monitored by different gateway nodes 120, and different gateway nodes 120 need to add their unique gateway identifiers when forwarding the data, so that the data from multiple channels (i.e., different wireless sensor nodes 110 and different gateway nodes 120) can be provided at the level of the block link point 130, thereby performing cross-validation of the data, preventing malicious tampering of the data, and avoiding the malicious behavior of the gateway.
The specific manner in which the consensus result is determined in relation to the formation of the consensus mechanism may also be determined according to different situations, for example:
if the same copies (with consistent content hash values) obtained by two different channels (determined to be from different gateway nodes 120) are received and the other copies are inconsistent, the content corresponding to the two same copies can be approved, and then the blockchain node 130 may record the monitoring data corresponding to the two same copies into the blockchain; if there are more than one set of identical copies, then the majority copy set (taking the most significant set of copies corresponding to the monitored data records into the block chain) is approved, and is not limited herein.
In this embodiment, the plurality of gateway nodes 120 (or the blockchain node 130) may be integrated or independent, and are not limited herein.
Here, for example, the operation of the wireless sensor network-based block chain system 100 will be briefly described:
firstly, the system can be initialized, the authentication center (which authenticates the gateway and the sensor, i.e. it is guaranteed that hardware entering the system is both in accordance with the standard and is an admission approval) issues the device list to the block link node 130 and forwards the gateway node 120, so as to ensure that the identities of the gateway node 120 and the wireless sensor node 110 which can enter the network can be verified and have unique identifiers (i.e. corresponding node identifiers), and the creation block of the block link node 130 can record basic information such as the digital certificate and the network identifier of the gateway node 120.
Then, the wireless sensor node 110 is powered on and initialized, and starts to monitor, so as to record the monitored transmission content (report data) of the relevant node, record a node identifier (a node identifier corresponding to the wireless sensor node 110 that reports data) and a content hash value (a content hash value corresponding to the transmission content), and attach the received record node identifier and the content hash value (which can be recorded and reported in a form of a list) when the node reports data.
After receiving the data reported by the wireless sensor node 110, the gateway node 120 may forward the data to the blockchain node 130 after verification.
As for the blockchain node 130, it may check, in each statistical period, that the hash value of the content of the node reported by each wireless sensor is identical to the hash value of the content of the node reported by other nodes, and if the hash values are identical, may record the data to the blockchain; if the inconsistency exists, the hash values of the contents of the nodes reported by other nodes can be counted, and 1/3 consistency, namely passing, is adopted to determine whether to count the data into the block chain or discard the data.
In order to facilitate understanding of the present embodiment, the following describes the verification and recording manner of the data in terms of the view of the block link point 130.

The blockchain node 130 may receive data forwarded by any gateway node 120, where the data includes monitoring data monitored by a wireless sensor node 110 and a corresponding node identifier, and a content hash value of a monitored related node and a corresponding node identifier. After receiving the data, the blockchain node 130 may obtain the monitoring data monitored by the wireless sensor node 110 and the corresponding target node identifier, and then generate a verification instruction and transmit the verification instruction to other blockchain nodes 130, where the verification instruction includes the monitoring data monitored by the wireless sensor node 110 and the corresponding target node identifier. And performing consistency check on the content hash value corresponding to the target node identifier in the statistical period and the monitoring data through other block link points to obtain corresponding check results, feeding back the corresponding check results to the block link point 130, and enabling the block link point 130 to obtain the check results fed back by each other block link point and determining whether to record the monitoring data into the block chain based on all the check results.
In order to further reveal the process of performing consistency check on the content hash value corresponding to the target node identifier and the monitoring data after the block chain node 130 receives the check instruction, a second data recording method is provided here.
Referring to fig. 3, fig. 3 is a flowchart of a second data recording method applied to the blockchain node 130. In the present embodiment, the second data recording method may include step S21, step S22, and step S23.
Step S21: and receiving a verification instruction transmitted by other block link nodes, wherein the verification instruction comprises a target node identifier and corresponding monitoring data, and the verification instruction is generated after the monitoring data monitored by the wireless sensor node and the corresponding target node identifier are acquired from data forwarded by any gateway node by other block link nodes.
Step S22: and determining whether a content hash value corresponding to the target node identifier exists or not in the statistical period based on the target node identifier in the verification instruction.

The blockchain node 130 may receive the verification command (including the target node identifier and the corresponding monitoring data) transmitted by the other blockchain nodes, and the verification command is generated for the other blockchain nodes. Then, the blockchain node 130 may determine whether a content hash value corresponding to the target node identifier exists in the statistical period based on the target node identifier in the verification instruction. And if the content hash value corresponding to the target node identification exists, performing consistency check on the content hash value and the monitoring data in the check instruction to determine a check result, and feeding back the check result to the block chain node for transmitting the check instruction so as to determine whether the monitoring data is recorded into the block chain or not by the block chain link point for transmitting the check instruction based on all the check results. The manner of determining whether to record the monitored data into the blockchain is described in detail above, and will not be described herein again.
