Abstract:

In order to resist the internal malicious attackers, protect the security of control instructions and industrial data, achieve the authentication of users and facilities, this paper designs a secure identity authentication protocol for the industrial Internet of things. Based on the realization of legitimacy verification, this paper introduces the mechanism of separation of users’ privilege and online registration of participating entities to improve the security and availability of the protocol. Finally, the security of the protocol is verified by simulation tool AVISPA and non-formal security analysis. Performance analysis and comparative analysis show that the protocol can be applied to industrial Internet of things identity authentication.

Key words: IIoT, authentication protocol, malicious user attack, online registration, privilege separation
