Terminal Trusted Authentication Technology for 5G Intelligent Lamp Poles Based on an Improved AES Algorithm Combining Random Key Generation and Clock Synchronization

This paper presents research on trusted authentication methods for IoT terminals, specifically focusing on the design of a secure lightweight trusted authentication module that integrates information abstracts and advanced encryption standard (AES) symmetric encryption algorithms for 5G intelligent lamp poles. The trusted authentication algorithm is designed using a variable key combined with the AES symmetric encryption algorithm to create an encryption application programming interface (API). The algorithm is then integrated into the hardware module, and an experimental platform is developed to demonstrate the effectiveness of the proposed trusted verification mechanism in preventing common network attacks.
