Most electronic auction schemes need trusted channels. If the communication channel is Incredible, trading parties' privacy information would be easily intercepted by an attacker. Some schemes can protect bidders’ privacy under untrusted channels, but these schemes usually use complex encryption technology, have poor efficiency. Established along the blind signature and one-way function, an electronic auction scheme is offered. The scheme needs not complex encryption and credible channel, has less computation, and is easy to program. So it can be used in the Internet large rang anonymous bid. Anonymity and security of all bidders, including lose bidder, have the same and important position in the proposed scheme, and are satisfied well too. Moreover, the proposed scheme has additional characteristics such as unforgeability, strong verifiability, non-repudiation, time limitation, fairness and high effectiveness.
