| 摘 要： | 在密封电子拍卖中,为了保证密封投标竞争的公平,电子拍卖系统需要保护已经提交到系统中的密封标书在开标前的信息安全.文中综合应用非对称密钥RSA、数字摘要和时间锁定等信息安全技术设计了密封电子拍卖RHT加密协议.该协议可保证加密后的标书信息在限定时间内不能够被任何人非法地解密.该协议不但可以认证投标各方的身份,而且能够保证标书信息的机密性、完整性和不可否认性,从而有效地满足了密封电子拍卖系统的安全性要求.

| Abstract: | In sealed-bid E-auction,an E-auction system needs to provide adequately safe protections of the information in the submitted bids before they are opened so as to guarantee the competition fairness in the sealed biddings.So sealed-bid E-auction RHT encryption protocol was designed with information security techniques such as RSA,Hash and time-release cryptography.RHT is proposed to encrypt a bid message so that it can’t be decrypted by anyone until a predetermined amount of time has passed.RHT not only can authenticate each bidder,but also guarantees confidentiality,integrality and undeniableness of the information.Thus RHT encryption protocol meets the security requirements of a sealed E-auction system effectively. |
