Abstract: A method is provided for transferring control of a security module from a first entity to a second entity. The security module has a first security domain controlled by the first entity by at least one first secret control key specific to the first entity, and a second security domain, the second domain containing a private key and a certificate of a public key of a controlling authority. The method includes: receiving a request to obtain the certificate; sending the certificate; receiving data encrypted by the public key of the certificate, the data including at least one second secret control key specific to the second entity; decrypting the data; verifying the data; and if the verification is positive, replacing the at least one first secret control key by the at least one second secret control key.

Abstract: The invention consists in a method of selecting an application from a plurality of applications installed in a security module, which method is adapted to dialogue with a communicating device and includes a preliminary configuration step (E0) including a step of determining at least one group of applications with which a group identifier is associated, a step of determining one application per group, and a step of storing configuration information representing the association of a particular application and the identifier of the corresponding group, step (E1) of receiving a selection instruction containing a group identifier sent by the communicating device, and a step (E2) of selecting the application associated with the received group identifier as a function of the stored configuration information. The invention also consists in a security module and a terminal.
