摘要
安全性是电子商务的一个前提。从保护投标者的角度出发,基于Lagrange插值法提出了一个完全匿名的安全电子拍卖协议。协议不仅能对除中标者外的其他所有投标者的投标价进行保密,还能有效地保护中标者的安全。而且,匿名机制也保证在整个电子拍卖过程中,无人可以操纵其他人的投标。同时,整个协议运行的通信代价很小,效率较高。
Security is the foundation of electronic business. Based on the Lagrange interpolation, this paper proposes a secure electronic auction protocol with full anonymity in the case of protecting bidders In our protocol, all bidders' bidding values are kept secret except for the winner's. The winner can be protected using anonymity and nobody can manipulate the other bidders in the whole auction. Meanwhile ,with the low communication cost,the protocol's efficiency is relatively high.
