Abstract

We propose a new untraceable electronic money system based on the discrete logarithm problem. Our system improves the efficiency of Yacobi's E-money system by making the applied blind signature partial. We compare our system to the previous e-money systems which use the E1Gamal-type scheme in their tracing a double-spender. We also remark a double-registration problem on a digital cash system, recently presented in [Nguyen-Mu-Varadharajan, in Information Security Workshop'97], based on the blind Nyberg-Rueppel signature.
