In order to ensure the security of the Internet of Things, it is necessary to authenticate the nodes in the architecture of the Internet of Things to prevent illegal node intrusion, illegal node data eavesdropping and other network attacks. In order to overcome this security threat and reduce the computing cost and other resource consumption of identity authentication in the Internet of Things, this paper designs a secure identity authentication method in the Internet of Things based on contact signals, which includes two parts: secure two-party identity authentication strategy and secure multi-party identity authentication strategy. The multi-party contact signal negotiation is completed by using the secure multi-party calculation method. In the process of secure multi-party identity authentication, an illegal node filtering mechanism is designed to improve the computing performance of secure multi-party identity authentication under the condition of illegal node attack.
