A method of receiving, by a terminal (11, 150), a rights object, RO, from a rights issuing server (40, 400) on behalf of a memory card (15, 150), the method comprising: receiving, by the terminal and from the rights issuing server, a trigger message for acquiring the RO from the rights issuing server; determining, by the terminal, whether one or more pairs of a trust anchor and an identifier, ID, of a memory card being included in the trigger message matches with a pair of a trust anchor and an ID of a memory card within a context of the terminal within a Secure Authenticated Channel, SAC, context which was generated by a mutual procedure between the terminal and the memory card; if a pair of a trust anchor and an ID of a memory card included in the trigger message matches with the pair of the trust anchor and the ID of the memory card within the context of the terminal within the SAC context: - transmitting, by the terminal, a RO request message including the ID of the memory card instead of an ID of the terminal to the rights issuing server; and - receiving, by the terminal, a RO response message including a protected RO from the rights issuing server; if none of the pairs of a trust anchor and an ID of a memory card included in the trigger message matches with the pair of the trust anchor and ID of the memory card within the context of the terminal within the SAC context, determining, by the terminal, whether the one or more pair of a trust anchor and an ID of a memory card being included in the trigger message matches with one of the pairs of a trust anchor and an ID of a memory card, that were received through a secure removable memory, SRM, hello response message from the memory card and are stored in the terminal; if a pair of a trust anchor and an ID of a memory card included in the trigger message matches with one of the pairs of 4 trust anchor and an ID of the memory card stored in the terminal, performing (S110'), by the terminal, a mutual authentication procedure with the memory card, wherein the mutual authentication procedure comprises: - transmitting an authentication request message to the memory card, wherein the authentication request message includes the pair of a trust anchor and an ID of the memory card determined as being included in the trigger message and stored in the terminal, and - receiving, by the terminal, an authentication response message including a processing status of the authentication request message from the memory card. receiving, by the terminal and from the rights issuing server, a trigger message for acquiring the RO from the rights issuing server; determining, by the terminal, whether one or more pairs of a trust anchor and an identifier, ID, of a memory card being included in the trigger message matches with a pair of a trust anchor and an ID of a memory card within a context of the terminal within a Secure Authenticated Channel, SAC, context which was generated by a mutual procedure between the terminal and the memory card; if a pair of a trust anchor and an ID of a memory card included in the trigger message matches with the pair of the trust anchor and the ID of the memory card within the context of the terminal within the SAC context: - transmitting, by the terminal, a RO request message including the ID of the memory card instead of an ID of the terminal to the rights issuing server; and - receiving, by the terminal, a RO response message including a protected RO from the rights issuing server; - transmitting, by the terminal, a RO request message including the ID of the memory card instead of an ID of the terminal to the rights issuing server; and - receiving, by the terminal, a RO response message including a protected RO from the rights issuing server; if none of the pairs of a trust anchor and an ID of a memory card included in the trigger message matches with the pair of the trust anchor and ID of the memory card within the context of the terminal within the SAC context, determining, by the terminal, whether the one or more pair of a trust anchor and an ID of a memory card being included in the trigger message matches with one of the pairs of a trust anchor and an ID of a memory card, that were received through a secure removable memory, SRM, hello response message from the memory card and are stored in the terminal; if a pair of a trust anchor and an ID of a memory card included in the trigger message matches with one of the pairs of 4 trust anchor and an ID of the memory card stored in the terminal, performing (S110'), by the terminal, a mutual authentication procedure with the memory card, wherein the mutual authentication procedure comprises: - transmitting an authentication request message to the memory card, wherein the authentication request message includes the pair of a trust anchor and an ID of the memory card determined as being included in the trigger message and stored in the terminal, and - receiving, by the terminal, an authentication response message including a processing status of the authentication request message from the memory card. - transmitting an authentication request message to the memory card, wherein the authentication request message includes the pair of a trust anchor and an ID of the memory card determined as being included in the trigger message and stored in the terminal, and - receiving, by the terminal, an authentication response message including a processing status of the authentication request message from the memory card.
