Identity authentication system for mobile terminal equipment based on SDN network

摘要

Aiming at the disadvantages of the existing mobile terminal equipment identity authentication system, such as poor anti-attack performance and slow speed, the mobile terminal equipment identity authentication system based on SDN network is designed. The architecture of mobile terminal device authentication system consists of sensor, data centre and management centre. This paper analyses the requirements and performance of mobile terminal device identity authentication system, processes the key information through the combination of hashing algorithm and public/key system, and determines whether the mobile terminal device is attacked, so as to realise the identity authentication of mobile terminal device. Experimental results show that when the number of network attacks is 30, the designed system can resist about 92% of the attacks, and the speed of identity authentication is always below 2.7 s, indicating that the system has good anti-attack performance and fast speed of identity authentication.
