Embodiment Construction

[0060] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0061] This embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. Those skilled in the art can make modifications to this embodiment without creative contribution as required after reading this specification, but as long as the claims of the present invention are protected by patent law.

[0062] Such as figure 1 As shown, the present invention provides a power block chain system based on trusted computing. The overall architecture includes three block chains: an authorization service chain, a log service chain, and a remote certification chain. Trusted chips are installed in the blockchain nodes of the authorization service chain, log service chain and remote certification chain, so that each node has strong identity authentication, and a trusted Internet of Things is jointly created through the det...

Abstract

The invention relates to the technical field of trusted authentication, and provides a trusted computing-based electric power block chain system, which comprises an authorization service chain, a logservice chain and a remote certification chain, trusted chips are arranged in blockchain nodes of the authorization service chain, the log service chain and the remote certification chain; the log service chain measures the reputation value of the collection layer terminal in real time through a malicious node detection mechanism based on an intelligent contract, discovers that the terminal can befound in time and removes the terminal out of the network, and prevents the malicious terminal from publishing malicious data. The log service chain and the remote verification chain perform remote integrity verification on the terminal requesting to access the system through the trusted chip; the authorization service chain carries out strategy verification on the terminal requesting to access the system. The system detects the access authority of a visitor through two aspects of integrity proof and access strategy verification, guarantees the credibility of an access terminal, comprehensively maintains the safe and credible operation of the power block chain system, and protects the private data in the power block chain.

Description

technical field [0001] The invention relates to the technical field of trusted authentication, in particular to a power block chain system based on trusted computing. Background technique [0002] The decentralized technology of the blockchain provides a reliable solution to the massive data and high concurrency problems in the power Internet of Things. However, since the blockchain mostly runs in an open and transparent environment, it is vulnerable to malicious attacks, resulting in sensitive data leakage. . [0003] The Chinese patent No. 2019108105818 discloses a ubiquitous power Internet of Things data transmission system, which provides a grid data transmission solution architecture that combines blockchain technology and edge computing technology, which can provide ubiquitous power IoT Networking provides data transmission security for local area networks, that is, through blockchain technology, it effectively avoids the hidden danger of data tampering during power g...
