Abstract (en)

[origin: FR2810139A1] The invention relates to a secure method for the pre- initializing phase of smart card (CP) with mutual authentication of the card, recording of a symmetric secret key (Km) and an asymmetric public key (Kpq), and a security access module (3) storing the same secret key and the asymmetric public key (Kpq) corresponding to the public key. The card (CP) and security access module (SAM) (3) supply random numbers (Nac). The SAM authenticates itself by transmitting a cryptogram (SR) to the card derived from two random numbers, using an asymmetric algorithm. The card authenticates itself by calculating a secret session key derived from the random numbers using a symmetric algorithm and the secret key and in transmitting to the SAM a cryptogram (CC) derived from the second random number, using the symmetric algorithm and the session key. The dedicated key (KF) is transmitted to the card encrypted using the session key. An Independent claim is made for an integrated system for implementing the method.
