Method for activating a third party application safely, a third party server, terminal and system

The invention relates to a method for safely activating the application of a third party, a third-party server, a terminal and a system. The method comprises the following steps: an initial security domain key applied by a third party is acquired by the terminal and the third-party server; a request for modifying the security domain key is triggered by the terminal, and a new security domain key is generated through negotiation with the same cryptographic algorithm with the third-party server, so as to update the initial security domain key; the related user information for activating the application of the third party is transmitted to the third-party server by the terminal; the application key of the terminal corresponding to the application of the third party is set by the third-party server according to the related user information; the updated security domain key is used for encrypting the application key of the third-party application by the third-party server and transmitting the application key to the terminal; the application key of the third-party application is acquired by the terminal through the decryption. The embodiments of the invention solve the problems that the current preset many-time writing card has lower efficiency and high cost, and the over-the-air downloading mode can not solve the problem of the privatization of the third-party security domain key.
