Abstract: In view of the difficult situation in identity authentication of the current intelligent lottery betting terminal, this paper proposes an authentication system adopting CPU card. The interaction way of client and server is ased to implement authentication function. The main process are the client reads the CPU card’s authentication information and transmits it to the server, and then the server returns the results to the client after validation. At the same time, stipulating for CPU card’s file structure, and introducing each functional module of CPU card certification system. Finally, through testing, we get the conclusion that the system is of high practicability and reliability.
