Abstract:

The identity authentication of nodes is the primary link of the security of the internet of things. However, the environment of the internet of things often involves identity authentication between multiple nodes, and the general internet of things identity authentication method is limited to two party identity authentication. A secure identity authentication method for internet of things based on contact signals is proposed in this paper. This method uses a secure multiparty calculation method for anonymity information anonymity and secret signal negotiation. It uses elliptic curve encryption algorithm to sign the information of the summary information and verify the signature for two-way identity authentication between multiple nodes and secure multi-party identity authentication. The results show that its cost of communication and computing is superior to the SMAOnEcc protocol and the NUASABEcc protocol.

Key words: internet of things security, identify authentication, secure multi-party computation, contact signals
