摘要
针对云资源拍卖过程中隐私泄露和公平支付问题,提出一种公平高效的安全双边云资源拍卖方案。基于加法秘密分享设计安全大小比较和安全排序等三方安全计算协议,由1台拍卖商服务器和2台代理商服务器高效协作执行安全拍卖协议,整个过程不泄露除拍卖结果以外的任何隐私信息,并且通过智能合约保证公平的交易支付。实验性能评估表明该方案计算和通信开销均优于现有方案。
Aiming at the problem of bid privacy leakage and fair dealing of cloud auction,an efficient,fair and secure double cloud auction was proposed.Based on the additive secret sharing,a series of secure computing sub-protocols including secure comparison and secure sorting were designed.An auction server and two agent servers cooperate to perform secure auction protocol efficiently,in which no sensitive information beyond the auction results is leaked.In addition,a smart contract guaranteed a fair dealing for cloud auction.Performance evaluation experiment results show that the scheme is outstanding in the computational cost and communication overhead compared with the existing works.
