METHOD AND SYSTEM FOR ACTIVATION

摘要

An activation method includes a security module card verifying an activation server using a shared secret key and a first challenge, mediating a verification of the activation server by a mobile device, and encrypting the second challenge using a generated key to obtain an encrypted second challenge. The security module card further transmits the encrypted second challenge and a third challenge to the mobile device. The method further includes receiving an encrypted third challenge from the mobile device, decrypting the encrypted third challenge to obtain a received third challenge, verifying the mobile device based on the received third challenge being equal to the third challenge sent to the mobile device, and sending a validation of mutual trust between the security module card and the mobile device to the activation server.
