Abstract:

Industrial internet of things is widely used in manufacturing, logistics, petroleum, aviation and other fields, which brings revolutionary opportunities for the production and operation of modern industry. However, due to the openness of the communication channel of the industrial Internet of things and the limited resources of the terminal equipment, the security, real-time and high efficiency of data and control instruction transmission are particularly important. Therefore, a secure and efficient authentication scheme for industrial Internet of things is indispensable. In recent years, most of the authentication schemes are vulnerable to privileged user attacks and terminal equipment tracking attacks. This paper designs an authentication scheme based on SGX for industrial Internet of things. The scheme uses SGX to store the master key and realizes the confidential computing by the characteristics of SGX memory confidentiality, which can effectively resist the privileged user attacks and the terminal equipment tracking attacks. Finally, the AVISPA simulation tool and the formal security analysis prove that the proposed scheme has more comprehensive security. The performance comparison and NS3 simulation prove that the scheme has better practicability and advanced nature.

Key words: industrial internet of things security, authentication scheme, confidential computing, privileged user attacks
