Abstract
As the latest generation of cellular mobile communication technology, the fifth-generation (5G) mobile communication technology is proposed to build a network-based society. As a result, industry and academia are placing great emphasis on security research for 5G technology. 5G technology has higher security requirements than previous systems and the secondary authentication is an important technology to ensure the security of 5G. In this paper, we propose to incorporate the SM9 encryption algorithm with 5G secondary authentication to provide higher security assurance. Due to the high computational overhead of the SM9 algorithm, we further propose an acceleration strategy for the SM9 algorithm based on the non-adjacent form (NAF) representation method to improve the performance of the entire system.
