SYSTEM AND METHOD FOR PERFORMING MUTUAL AUTHENTICATION BETWEEN MOBILE TERMINAL AND SERVER

摘要

The present invention relates to system and method for performing mutual authentication between mobile terminal and server. Server and mobile terminal have particular information of the mobile terminal in common, and use predetermined authentication information generating algorithm which requests random number and particular information of the mobile terminal as input data. Each of server and mobile terminal challenges the other with random number, and determines authenticity of the other side by the response to the challenge. By the authentication process and using it mutually, the server and mobile terminal can be mutually authenticated and then data transmitted by the server or mobile terminal can be authenticated. Thereby, the transmission to unjust mobile terminal and the transmission from unjust server can be protected. And by including random number and authentication information within data transmission procedure, protection from unjust transmission can be achieved with minimum of information and a simple procedure.
