Identity Authentication Protocol of Smart Home IoT based on Chebyshev Chaotic Mapping

Abstract

With the rapid development of the Internet of Things technology, the security of the Internet of Things is becoming increasingly important. Internet of Things (IoT) identity authentication is an important means to ensure network security. However, common identity authentication protocols have problems such as insufficient security factor and low efficiency. A smart home IoT identity authentication protocol based on Chebyshev chaotic map is proposed to improve the security of identity authentication. To solve the problem of low security of session key, the LAoCCM identity authentication protocol based on Chebyshev chaotic map is proposed to update session key. To solve the problem that the number of chaotic maps is too high, AEAD algorithm is introduced to reduce the number of chaotic maps. The results show that the average authentication error of LAoCCM authentication protocol is 0.00085, which is significantly smaller than that of EDHOC and ZKOP authentication protocols. Therefore, the proposed LAoCCM identity authentication protocol based on Chebyshev chaotic map has higher security performance and authentication efficiency, which can effectively meet people's needs for information security of smart furniture
