摘要 |
A method and a system for use for safe data transfer between a terminal which is controlled by an IC card (1), and a central unit (3), such as a central computer in a bank. The IC card (1) comprises card-specific program information which is used to control the interaction of the card with the terminal (2) in connection with adopting a safe system mode, and card-specific secret information which is used to cryptographically protect data transfers between the terminal (2) and the central unit (3) in a safe system mode. The card specific secret information is stored in such a manner that no read-out of it can be made from the card. The card-specific program information is transferred from the card to the terminal for the purpose of said control. |
