ABSTRACT:
The presently used Asymmetric Digital Signature verification technologies, such as the system of RSA Data Security Corp., require complex mathematical operations for encryption and decryption. As a result, today's smart credit cards have built-in microprocessors, sophisticated arithmetic/logic units, and large amounts of RAM and ROM. For smart card applications, both the cost and the complexity of such systems is prohibitive. The present invention introduces a smart card technology that uses fairly simple logic circuitry, together with a novel handshaking technique, to achieve an outstanding level of security while maintaining simplicity and low cost.
