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