An Electronic Cash Scheme with Crime-Resistance

Abstract

One of the potential problems with electronic cash schemes is the perfect crimes. No one can trace back to a particular owner after the message-signature pair is published. Therefore, a malicious adversary may make use of this unconditional anonymity to blackmail or kidnap someone to get clean and untraceable money. In this paper, we propose an electronic cash scheme satisfying all the security requirements of electronic cash systems. Also, we believe that our e-cash scheme can resist the perfect crimes.
