Problems solved by technology

[0003] In the field of mobile communication, there are many methods of two-way authentication. For example, the Chinese patent application number 01109822 proposes a method for realizing two-way authentication in a cellular mobile communication network e-commerce micro-payment system, but the method simultaneously Also need to adopt bluetooth technology to realize, and can only realize short-distance two-way authentication, so this invention can not solve the function of realizing the two-way authentication of long-distance mobile station in any network coverage place in code division multiple access system

Abstract

The invention provides a code division multiple access system that realizes the two way authentication comprising a mobile station, a base station and a switchboard, characterized by that, the system also includes an authentication algorithm unit on the mobile station side, an authentication algorithm unit and transfer unit on the switchboard side, the authentication algorithm unit on the mobile station side exchanges the authentication information with the mobile station through the internal interface, the authentication algorithm unit on the switchboard side connects with the transfer unit through the internal interface, for interactively realizing the related information needed by the two-way authentication. The system and method by the invention can guarantee the dependability and real time property of the authentication information transfer.

Description

technical field [0001] The invention relates to the field of code division multiple access, in particular to a method for realizing two-way authentication in a code division multiple access mobile communication system. Background technique [0002] Most of the existing CDMA cellular systems only provide the function of one-way authentication. This function is mainly used for the base station to authenticate the mobile station and confirm the legitimacy of the mobile station. However, this one-way authentication function has certain limitations and cannot be applied to some special authentication requirements. In some special services, not only the base station needs to identify the legitimacy of the mobile station, but also the mobile station needs to confirm the legitimacy of the base station, thus creating a requirement for two-way authentication. [0003] In the field of mobile communication, there are many methods of two-way authentication. For example, the Chinese pate...
