Industrial Internet data security monitoring method and system based on block chain

Abstract

The embodiment of the invention provides an industrial Internet data security monitoring method based on a block chain. The method comprises the following steps that the block chain acquires a homomorphic tag corresponding to monitoring data through an intelligent contract; the block chain opens the access permission of the intelligent contract to an authorization verifier, so that the verifier can obtain the homomorphic tag and send challenge information generated according to the homomorphic tag to the cloud; the block chain opens the access permission of the intelligent contract to the cloud, the cloud can acquire the homomorphic tag and send the certificate generated according to the homomorphic tag and the challenge information to the verifier, so that the verifier can perform comparative analysis according to the certificate to judge whether the integrity of the monitoring data is damaged or not, and a reliable data basis is provided for industrial Internet data security monitoring. The embodiment of the invention further provides an industrial Internet data security monitoring system based on the block chain. According to the invention, reliable protection can be provided for data security of the industrial Internet.

Description

technical field [0001] The invention relates to the technical field of industrial Internet data security, in particular to a block chain-based industrial Internet data security monitoring method and system. Background technique [0002] The data security protection of the Industrial Internet includes the security protection of the data collection side of the physical equipment, the security protection of the data communication network, and the security protection of data storage and sharing. Strong identity authentication of industrial Internet equipment, and then protect the authenticity and credibility of equipment identity from the chip level. However, the labeling, certificate issuance, and identity authentication of physical devices are confirmed and issued by a centralized organization. Therefore, there are risks of human tampering and failure of the central organization after being invaded. [0003] At the same time, the process of data storage and sharing may also b...

AI Technical Summary

Problems solved by technology

However, the labeling, certificate issuance, and identity authentication of physical devices are confirmed and issued by a centralized organization. Therefore, there are risks of human tampering and failure of the central organization after being invaded.

[0003] At the same time, the process of data storage and sharing may also be tampered with and leaked, requiring irregular data inspections

However, most of the data integrity verification mechanism and security sharing mechanism in the existing technology are based on key exchange technology and third-party verification. During the verification process, a large amount of auxiliary information needs to be stored, and there are problems such as falsification of verification results and key leakage.

[0004] In addition, the log information obtained after each system monitoring and verification is stored on a centralized server, which is also vulnerable to external malicious intrusion and tampering, resulting in no accountability for industrial Internet data security incidents
