In this paper we have designed a fair e-cash system using Schnorr’s one-time signature and Okamoto-Schnoor blind signature. In addition, the proposed e-cash system is constructed using elliptic curve cryptosystems (ECC) under the limited-storage environment for mobile devices such as smart cards, PDA etc able to efficiently store the coin streams. Furthermore, this system prevents criminal’s activities by means of the two common cryptographic techniques double-spending detection and fair tracing.
