Abstract
A system and methods for implementing a low cost and simple PIN encryption device is disclosed. The PIN encryption device may be incorporated into customer transaction terminals, ATMs and PIN pads for use with POS terminals or other transaction devices. The PIN encryption device securely stores PIN encryption keys and PIN encryption algorithms that are used to encrypt user entered PINs on a cryptographic smart card. The system disclosed is a physically secure device that protects the integrity of the encryption keys and algorithms. The system also protects the cryptographic smart card from tampering, and prevents the discovery of PIN data by tapping the external interfaces of the customer transaction terminal.
