  • Integrity protected smart card transaction
    Patent number: 9305156
    Abstract: Systems, methods, and technologies for configuring a conventional smart card and client machine, and for performing a smart card authorization using the configured smart card and client. Further, the combination of methods provides for mutual authentication—authentication of the client to the user, and authentication of the user to the client. The authentication methods include presenting a specified token to the user sufficient to authenticate the client to the user and thus protect the user-provided PIN. Security is strengthened by using an integrity key based on approved client system configurations. Security is further strengthened by calculating a PIN? value based on a user-specified PIN and a modifier and using the PIN? value for unlocking the smart card.
