Trusted Attestation Protocol for Power Internet of Things

With the increasing level of automation in the power system, the scale and complexity of the power Internet of Things are also constantly increasing. However, with the increase in the scale of the power Internet of Things, the security risks it faces are also constantly increasing. The data and information involved in the power Internet of Things contain a large amount of sensitive information, such as user information, power equipment information, energy management information, and so on. Once this information is leaked or tampered with, it will cause great losses to the power system. Therefore, the security issue of the power Internet of Things has become an urgent problem to be solved. Therefore, this article proposes a trusted attestation protocol for the power Internet of Things, which comprehensively evaluates and authenticates the identity, security, and credibility of terminal devices, ensuring that terminals can access network communication while complying with security policies in the "cloud edge end" environment, ensuring the security of the communication network. This protocol can prevent malicious access from non trustworthy IoT terminals, improve the reliability and security of the entire power IoT system, and thus ensure the stable operation of the power system.
