Abstract: Method and apparatus for producing a key common to two devices, belonging to different sets, for implementing a common cryptographic procedure. According to the invention, each device is assigned a mother key (KC, KP), and at least one daughter key (KPck, PCpi) based on the mother key of the other device and on the identification data belonging to the device. During the procedure, both devices exchange their identification data (ck, pi) which, when processed with the assigned mother key, provide the daughter key (KCpi, KPck) of the other device. The pair of keys consisting of the assigned daughter key and the calculated daughter key forms the common key.

Abstract: Method and arrangement for providing selective access to a security system (6), in particular, a payment system involving a debit or credit card, or transfer of money values using an electronic card (1) such as a smart card. The system (6) comprises at least one first device (7) and at least one second device (8) which have to be matched to obtain access. Such access is obtained by verification that a cryptographic key (K2) contained in the second device (8) is recognized as being valid by the first device (7) after being compared with a key (K1) belonging to the latter.
