1. at mobile communication equipment (115), above implement the system of security strategy for one kind, described mobile communication equipment (115) and subscriber identity module (120) in operation explicitly for mobile communications network (105), described system has client-server architecture, and comprises:

  • Server (140) by mobile communication network operator (110) operation;

    Reside in the client computer (135) on mobile communication equipment, wherein will on described mobile communication equipment, implement security strategy;

    Wherein said server is determined the security strategy of applying on described mobile communication equipment, and security strategy to be applied is sent to described mobile communication equipment, wherein said server comprises for authentication and will be sent to the server authentication functions (327) of the security strategy of described mobile communication equipment;

    And wherein said client computer receives security strategy to be applied from described server, and apply the security strategy of described reception, described client computer also resides in the client authentication function (435) in described subscriber identity module by use, the authenticity of the security strategy that evaluation receives from described serverIt is characterized in that,Described server authentication functions is used for;

    -calculate for allowing evaluation to be sent to the authentication information of authenticity of the security strategy of described mobile communication equipment, and described authentication information is added in described security strategy;

    And-by calculating be used for allowing evaluation by the transmission that is sent to described mobile communication equipment through the message authentication information of the authenticity of the message of the security strategy of authentication and add described message authentication information to sent message and carry out message described in authentication;

    AndDescribed client authentication function is used for;

    -by the message for receiving from described server, calculate message authentication information, evaluate the authenticity of the message receiving from server;

    -compare the message authentication information of calculating and be included in the message authentication information in received message;

    -for the security strategy compute authentication information receiving from described server;

    With-compare the authentication information calculating and be included in the authentication information in received security strategy.
