  • storing, at a server system, registration data associated with the target mobile device, the registration data including the command encryption key for encrypting commands for the target mobile device;

    while the server system is authorized to generate security commands for the target mobile device through possession of the command encryption key;

    encrypting the security command using the command encryption key; and

    storing the encrypted security command at the server system; and

    after the server system is subsequently configured such that the server system is no longer authorized to generate security commands for the target mobile device, wherein configuring the server system to be no longer authorized to generate security commands for the target mobile device comprises deleting the command encryption key from the server system without deleting the stored encrypted security command;
