The secure element comprises a storage unit, in which a set of computer-readable instructions for mutual authentication of the secure element with an external entity, a static key pair, and a receipt are stored. The secure element comprises a control unit which is configured to execute the set of computer-readable instructions which configure the control unit to: initiate a secure channel; generate at least one shared secret by executing an elliptic curve key agreement based on the static key pair; generate at least one session key for secure messaging over the secure channel based on the at least one shared secret and shared information, wherein the shared information includes the receipt; determine a new receipt based on one of the at least one session key; and store the new receipt in the storage unit.
