Patent

CA 2578608

A system and method for securing a central processing unit and/or encrypting pin pad (EPP) for an automated teller machine from tampering is disclosed. A user input is provided that has a plurality of input keys for allowing associated users to enter information by depressing the input keys. The input keys include key contacts and conductive traces that lead to a processing unit and other security features. In general operation, the key contacts and traces are measured and/or read for capacitance and resistance and are compared against prior readings to establish base for next sequences. If base readings are significantly out of tolerance or if other security features generate a fault condition, a tamper response is triggered, which causes erasing (e.g., zeroing) of cryptographic information contained in the security processor and renders unit inoperable.
