一种基于联络信号的物联网安全身份认证方法

A Kind of Secure Identity Authentication Method Based on Contact Signals for Internet of Things

节点身份认证是物联网安全首要环节,物联网环境常涉及多个节点之间的身份认证,一般物联网身份认证方法局限于两方身份认证。文章提出一种基于联络信号的物联网安全身份认证方法,该方法使用安全多方计算方法对联络信号信息匿名,完成联络信号协商,使用椭圆曲线加密算法对摘要信息签名及签名验证。文章还设计了安全多方身份认证机制,完成多个节点之间双向身份认证。相对于SMAOnEcc协议和NUASABEcc协议,该方法在通信量和计算花费方面更具优势。

The identity authentication of nodes is the primary link of the security of the internet of things. However, the environment of the interact 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.
