摘要
大多数电子拍卖方案都需要第三方的仲裁机构协助实现拍卖,如果第三方与卖方或买方合谋,买方的投标价与卖方的一些商业秘密将会泄露。针对该问题,结合Bit承诺与盲签名技术,提出一种基于不可信第三方仲裁机构的密封式拍卖方案。该方案满足一个安全的电子拍卖方案的要求,可有效地避免上述合谋攻击。
Most electronic auction schemes need assistance of a third-party arbitration organization.If the third-party conspires with seller or buyer,buyer’s bid price and seller’s trade secret would be disclosed.Combining with the technology of Bit commitment and blind signature,this paper proposes an electronic auction scheme based on trustless third-party.It meets the demand of a secure electronic auction scheme,and it can withstand the above conspiracy attack.
