ABSTRACT:
To provide protection for the use of chip cards, the microprocessor of such a card is made, during the use of the card, to compute a signature according to complex encrypting algorithm taking account, firstly, of a secret code proper to the card and, secondly, of the instructions proper to the program. The signature thus computed is compared with a signature that has been pre-recorded in the card under the same conditions at the time of its delivery by the card-issuing party. It is shown that several uses can be authorized without jeopardizing their security.
