Authentication method and system with a smartcard |
摘要 |
This invention relates to a novel smartcard-based authentication technique using a smartcard that encrypts the time displayed on the card with a secret, cryptographically strong key. The (public) work station receives as input certain values defining the user, the card and a particular value derived from the encrypted time and encrypts and/or transmits these values to the server. The server, in turn, computes from received values some potential values and compares these to other received values. If the server determines a match, an accept signal is transmitted to the work station.
