1. a storage card that is installed in this terminal by terminal representative receives permission object (RO) and the RO that receives is installed in method the described storage card from authority distributor (RI), comprising:

  • By the RO response message that comprise device id, shielded RO and signature of described terminal reception from described RI;

    Determine whether the described device id in the described RO response message is matched with the ID of described storage card;

    If the described device id in the described RO response message and the ID of described storage card coupling is then extracted the cryptographic cipher key material of packing and information producing authority information by described terminal, and is produced the identifier that identifies described authority information from described shielded RO;

    To comprise the cryptographic cipher key material of described packing, described identifier and request message will be set and be sent to described storage card from described terminal about providing of the information of the size of described authority information;

    Receive to provide from described storage card by described terminal response message is set, the described authentication secret that the state that response message is set comprises that indication is handled provides the result that request message is set is provided, from the cryptographic cipher key material of described packing, obtains by described storage card;

    Use described authentication secret to verify described RO;

    Provide request message to be sent to described storage card so that described authority information is installed in the described storage card from described terminal authority, described authority provides request message to comprise described identifier and described authority information;

    AndComprise that from described storage card reception the authority of authority information installment state provides response message by described terminal.
