Abstract
A PIN device utilizes a preferably removable IC card to store and process data to provide a tamper resistant PIN entry system. The IC card is a tamper resistant module that provides four functions for the PIN device. The IC card: stores secure data for the PIN device; provides authentication for verifying that the IC card can be trusted; provides a mechanism for the loading of secure data into the PIN device; and provides a mechanism to authenticate its identity to other parties. The subject PIN entry system allows for servicing of the PIN device in the field.
