An effective anonymous authentication and key negotiation protocol for legal system network
Zhiyu Zhang, Nan Xiao · Alexandria Engineering Journal · 2024
In recent years, legal system is gradually moving towards digitalization and networking, which has brought unprecedented improvement to the convenience and efficiency of legal services. The construction and implementation of legal system network has established a unified legal management information platform, standardized business processing procedures and improved work efficiency. However, cybersecurity issues are becoming increasingly prominent and are one of the key factors constraining the digitalization process of the legal system. Especially how to ensure the authenticity of user identity and the security of communication has become an important challenge faced by legal system network. Therefore, we propose an efficient anonymous authentication and key negotiation protocol for legal system network. This protocol generates entity authentication key through chebyshev chaotic mapping and uses a three-factor authentication mechanism to enhance security. Finally, the model and scyther tool prove that the protocol is secure and informal analysis verifies its effectiveness in security features. The experimental findings demonstrate superior computational efficiency and enhanced security.
