In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
Example one
Fig. 1 is a schematic flow chart of a real-time updating method of an internet of things online consensus node based on a block chain in the embodiment of the present invention. As shown in fig. 1, an embodiment of the present invention provides a real-time update method for an online consensus node of an internet of things based on a block chain, where the method includes:
step 110, obtaining M consensus nodes, wherein M is an integer greater than 0;
in particular, a blockchain is a distributed database, which is embodied in a distributed manner as distributed storage and distributed recording of data, i.e., the data is recorded, stored and maintained collectively by participants of a data system. The block chain can generate a set of database which records time sequence, cannot be tampered and can be trusted, the set of database is decentralized to store, and data security can be effectively guaranteed. The blockchain technology is a technology for maintaining a reliable database in a decentralization and distrust mode body. In order to prevent the waste of data management resources caused by the fact that too many invalid data are uploaded to a server due to the fact that the number of terminals in the Internet of things system is too large. We need to select and initially define a partial terminal as a consensus node in the blockchain, where M is the partial terminal and initially defines it as the number of consensus nodes in the blockchain.
Step 120, obtaining N real-time online consensus nodes from the M consensus nodes, wherein N is an integer greater than 0 and is less than or equal to M;
specifically, the M consensus nodes include all consensus nodes, and in an internet of things system with "low power consumption" as one of the main advantages, the terminal is in a dormant state most of the time, and the consensus nodes in the dormant state cannot provide effective data screening and auditing, so that some of the M consensus nodes are in an online state, some of the consensus nodes are in the dormant state, and N real-time online consensus nodes are assumed to be in the M consensus nodes, where a value of N changes in real time and N is less than or equal to M.
Step 130, an identity list of the consensus nodes is set in each consensus node, wherein the identity list comprises identity information, online quantity and online state information of each consensus node;
specifically, the steps described in this embodiment of the present application do not represent any sequence, and may be performed in multiple steps simultaneously or in sequence, where various sequences are within the protection scope of the embodiment of the present application, each consensus node has an identity list of the consensus node and a current online state list, and the identity list and the current online state list may be initialized when the consensus node leaves a factory or set when each node is powered on, and the list includes the number of current online consensus nodes, the identities of M consensus nodes, and online state information.
Further, after obtaining N real-time online consensus nodes from the M consensus nodes, the method includes: obtaining a predetermined audit threshold; acquiring real-time monitoring data of all terminals in the Internet of things system on the consensus node; auditing the real-time monitoring data to obtain the auditing passing rate of the consensus node; judging whether the auditing passing rate exceeds the preset auditing threshold value or not; if the audit passing rate exceeds the preset audit threshold value, determining that the real-time monitoring data are valid, and storing the real-time monitoring data into a chained database; and if the audit passing rate does not exceed the preset audit threshold value, determining that the real-time monitoring data is invalid, and discarding the real-time monitoring data.
Further, the auditing the real-time monitoring data to obtain the auditing passing rate of the consensus node includes: auditing the real-time monitoring data to obtain the number of approved audits of the consensus nodes; and obtaining the passing rate of the audit according to the number of the audit passes and the total number of the real-time online consensus nodes.
Specifically, real-time monitoring data of all terminals in the internet of things system need to be sent to each online consensus node in real time for screening and auditing. The preset auditing threshold value is preset according to actual conditions, specific numerical values are limited in the application, and if the auditing passing rate exceeds the threshold value p%, the data is considered to pass the auditing and needs to be stored in a chain database for processing analysis and storage maintenance. Here, the audit passing rate means that if N × p% of the N online common identification nodes audit and determine that the data is valid, the data is considered to be valid and the data passes the audit. And the audit passing rate is the ratio of the audit passing number of the consensus nodes to the number of all the online consensus nodes. And if the audit passing rate does not exceed the preset audit threshold value, determining that the real-time monitoring data is invalid, and discarding the real-time monitoring data. The application of the block chain provides great guarantee for the safety of system data, the screening and the auditing of the consensus nodes ensure the validity of the data stored in the database, and the utilization rate of storage, maintenance and management resources is improved; the structure of the chain database ensures that the data information stored in the database cannot be illegally modified and attacked, and prevents the data from being tampered or lost.
Step 140, obtaining a first online consensus node from the N real-time online consensus nodes;
specifically, the first online common node is a common node among the current N online common nodes.
Further, before determining whether the online status of the first online consensus node enters the dormant state, the method further includes: acquiring identity information of a first online consensus node; judging whether the identity information of the first online consensus node is the same as the identity information of the first online consensus node in the identity list or not; if the identity information of the first online consensus node is the same as the identity information of the first online consensus node in the identity list, judging whether the online state of the first online consensus node enters a dormant state or not; and if the identity information of the first online consensus node is different from the identity information of the first online consensus node in the identity list, stopping judging whether the online state of the first online consensus node enters a dormant state or not.
Specifically, in order to prevent a malicious node from being disguised as the first common node transmission information, the condition of the identity recognition step should be added before the online state of the first common node is judged. And receiving the identity information of the first online common identification node, comparing and verifying the identity information sent by the first common identification node with the identity information of the first common identification node stored in the identity list, and performing subsequent online state judgment only after verification is passed. Authentication methods herein include, but are not limited to, asymmetric encryption.
Step 150, judging whether the online state of the first online consensus node enters a dormant state;
specifically, each consensus node includes an identity list of M initial consensus nodes and a current online state list, and changes of list information are synchronized in each consensus node in real time, so that what state the first online consensus node is in can be known according to the changes of the list information, including a dormant state, a state of going online again after dormancy, and a state of keeping online unchanged. And judging which state of the three situations the first online common node is in.
And step 160, updating the number of the real-time online consensus nodes according to the online state of the first online consensus node.
Specifically, the number of the real-time online consensus nodes is updated according to the online status of the first online consensus node, and specifically, identity lists are synchronized among all real-time online consensus nodes. If the first consensus node is recovered to be online again from the dormant state, the online change conditions of other consensus nodes are not clear during the dormancy, and the stored identity list needs to be kept consistent with other nodes; in addition, other real-time online consensus nodes may cause inconsistency of the stored identity lists due to the network or due to self-judgment, and in order to eliminate such an error, the identity lists stored among all real-time online consensus nodes need to be updated synchronously. Therefore, real-time online consensus node information in the block chain can be obtained, the auditing passing rate can be reasonably calculated when the data reported by each terminal is screened and audited, and whether the reported data is effective or not and whether the reported data is uploaded to a correct conclusion of storage analysis of the server or not can be obtained.
The following specifically explains how to update the number of the real-time online consensus nodes for three different states of the first online consensus node.
Further, the updating the number of the real-time online consensus nodes according to the online status of the first online consensus node includes: if the online state of the first online consensus node is in a dormant state, sending first informing information to the rest M-1 consensus nodes, wherein the first informing information is used for informing the M-1 consensus nodes to update the online state of the first online consensus node to be in the dormant state; and updating the number of the online common identification nodes to be N-1 according to the first notification information.
Specifically, when a certain common node X of the current N online common nodes enters a sleep state, the node X sends active notification information, that is, the first notification information, to the remaining M-1 common nodes, where the first notification information includes the identity information of the first online node in addition to the online state update of the first common node to the sleep state. The identity information is used for the receiving node to authenticate the receiving node. Therefore, the state of X in the list is changed from an online state to a dormant state, the number of online consensus nodes is changed into N-1, whether the data uploaded by the terminal passes the audit or not is judged, the data can pass the audit only by judging that (N-1) × p% nodes are effective, and the change of the information is synchronized in each consensus node in real time.
