The first embodiment is as follows:
referring to fig. 1, an information interaction method of a monitoring terminal according to an embodiment of the present application is described below, where the information interaction method of the monitoring terminal according to the embodiment of the present application includes:
s101, acquiring first data, and performing hash calculation on the first data to obtain a first hash value;
the network topology structure of the internet of things of the traditional monitoring equipment is a centralized network topology structure, information interaction cannot be directly carried out among all the monitoring equipment, the monitoring equipment must transfer information through an upper network center, information delay and packet loss easily occur, access between the monitoring terminals is difficult abnormally, interconnection and intercommunication information sharing among the monitoring terminals is hindered, the resource utilization rate is reduced, and because the information needs to penetrate through a multilayer network in the transfer process, data cannot be guaranteed not to be maliciously tampered, and once the upper network center breaks down, all the monitoring equipment become independent information islands, and information interaction cannot be carried out with other monitoring equipment completely.
Therefore, in the information interaction method for the monitoring terminal in this embodiment, each monitoring device establishes a decentralized blockchain network, and performs information interaction through the blockchain network, and a node in the blockchain may be a monitoring terminal or an upper network device (such as a backend or a cloud server, a database), that is, the monitoring terminal may register on other monitoring terminals or an upper network center, and each node has an equal status, and each node may directly send data to the blockchain network to perform data interaction with other nodes, so that occurrence of information delay and packet loss is reduced, and even if part of the nodes are broken down, other nodes may also perform information interaction normally.
In addition, the blockchain is a chain data structure formed by combining data blocks in a sequential connection mode according to a time sequence, and is a distributed account book which is guaranteed to be not falsifiable and counterfeitable in a cryptographic mode, so that once the data is linked up, the data recorded by the blockchain can be guaranteed to be not falsified.
In a block chain network, the validity and authenticity of first data need to be verified through public and private keys of data publishing nodes and hash values, so that when a monitoring terminal needs to publish the data, hash calculation needs to be performed on the first data to be published first to obtain the first hash value.
The hash calculation can compress a message with any length into a hash value (message digest) with a certain fixed length, when the compressed message slightly changes, the hash value greatly changes, and the hash value cannot be reversely deduced and restored into the compressed message, so that the first hash value can be used for verifying the authenticity of the first data.
Step S102, integrating the first data and the first hash value into a first data packet, encrypting the first data packet by using a first private key, and broadcasting the encrypted first data packet to a block chain.
In addition, besides verifying the authenticity of the first data and avoiding the first data from being tampered, the identity of the first data issuer needs to be verified, so as to determine the validity of the first data, therefore, the monitoring terminal can integrate the first data and the first hash value into a first data packet, the first data packet is encrypted by using a first private key, the encryption process is the signature process of the monitoring terminal, and if other nodes can decrypt by using the public key of the monitoring terminal and successfully verify the signature, the authenticity of the identity of the data issuer can be verified, so as to determine the validity of the first data.
The first data packet can be broadcasted to the blockchain after being encrypted, other nodes can directly acquire the encrypted first data packet from the blockchain network without being transferred through centralization, and even if part of the nodes are broken down, other nodes can normally perform information interaction, so that the stability and reliability of the network topology structure are enhanced.
Further, the method further comprises:
a1, receiving an encrypted second data packet broadcasted into the block chain, and decrypting the encrypted second data packet by using a second public key to obtain a decrypted second data packet;
when the monitoring terminal receives the encrypted second data packet broadcast to the block chain by other nodes, the encrypted second data packet can be decrypted by using a second public key to obtain a decrypted second data packet, wherein the second public key is the public key of the node issuing the encrypted second data packet.
A2, performing hash calculation on the second data in the decrypted second data packet to obtain a verification hash value, and judging whether the verification hash value is consistent with the second hash value in the decrypted second data packet;
and performing hash calculation on the decrypted second data in the second data packet to obtain a verification hash value, verifying the authenticity of the second data in the second data packet according to the verification hash value, and judging whether the verification hash value is consistent with the second hash value.
A3, when the verification hash value is consistent with the second hash value, the encrypted second data packet is verified.
When the verification hash value is consistent with the second hash value, the encrypted second data packet passes verification, and the second data can be recorded in a local block chain, wherein the second data is real and reliable.
When the verification hash value is inconsistent with the second hash value, the second data in the encrypted second data packet is changed, and at the moment, the encrypted second data packet fails to be verified and is not recorded or stored.
Meanwhile, each node stores a complete blockchain, so that even if part of nodes fail or cannot receive data offline, when the node breaks down or goes online again, corresponding blockchain data can be synchronized from other nodes.
In the information interaction method for the monitoring terminal provided in this embodiment, the monitoring terminal performs networking and data interaction in the form of a blockchain, the blockchain is a decentralized data interaction and storage mode, any node can directly perform data interaction without transferring through a multi-layer upper network center, difficulty in sharing interconnection and intercommunication resources between different monitoring terminals is reduced, occurrence of information delay packet loss is reduced, and when the blockchain is used for performing data interaction and recording, the blockchain can ensure that data is not tampered and not forged in a cryptographic manner, and the problems that when the existing monitoring terminal performs information interaction, information delay packet loss is easy to occur, and malicious tampering of information in a transmission process cannot be ensured are solved.
When the monitoring terminal receives the second data packet issued by other nodes, the validity and the authenticity of the second data can be verified according to the second public key and the verification hash value corresponding to the data issuing node, so that the data recorded in the block chain are ensured to be real and reliable data.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
