ABSTRACT:
A method of securely transferring data, such as program data, to a smart card (1) is disclosed. In order to be applicable in non-secure environments, the method of the invention involves a one-way authentication mechanism, comprising the use of a series of interrelated authentication values (R0, R1, R2, . . . ). Further security is achieved by using commands (INIT, TRAN) which are each provided with an authentication code (MAC0, MAC1, . . . ). In order to transfer data only to selected cards, the card may accept transfer commands only if a card profile (CP) matches a distribution profile (DP).
