Security Analysis of Communication Data of Intelligent Integrated Cabinet System Based on SM9 Algorithm

With the rapid development of information technology, intelligent integrated cabinet systems are widely used in the industrial field, playing a key role in information transmission. However, these systems are facing increasingly severe network security threats, and effective security protection mechanisms are urgently needed. In this paper, the security of communication data of intelligent integrated cabinet system based on SM9 algorithm is analyzed in depth. This paper summarizes the working principle of intelligent integrated cabinet system and the security challenges it faces. Then, based on the SM9 algorithm, an identity-based secure communication scheme is proposed to protect the data transmission between devices within the system. The scheme effectively enhances the confidentiality, integrity and reliability of the communication data through the mechanisms of identity authentication, encryption and digital signature. It is found that compared with the traditional public key infrastructure (PKI) scheme, the identity encryption scheme based on the SM9 algorithm has obvious advantages in terms of computational overhead, key management, etc., and is more suitable for embedded devices with limited resources.
