    • An auction verification subsystem provides verification, without revealing actual bid values, that bid values remained sealed prior to a closing time for the auction and that an announced winning bidder for the auction provided a highest bid. The verification subsystem receives encrypted bids from bidders and generates commitment data based on the bids and provides the commitment data to each of the bidders. In response to receiving the commitment data, the bidders provide decryption keys for the encrypted bids. In turn, the bids are decrypted and an auction is performed using the decrypted bids. The results of the auction can be verified based on bid representations that do not reveal the actual values of bids, thereby maintaining the secrecy of bids. Providing access to an exchange between bidders and the verification subsystem facilitates verification that the auction is performed as a sealed bid auction.
    • 拍卖验证子系统在不透露实际出价值的情况下提供验证,即在拍卖的关闭时间之前投标值保持密封,并且所宣布的拍卖中标者提供最高出价。 验证子系统接收来自投标人的加密投标并基于投标产生投标数据,并向每个投标人提供投标数据。 响应于接收到承诺数据,投标人为加密出价提供解密密钥。 反过来,这些出价被解密并且使用解密的出价执行拍卖。 拍卖的结果可以基于没有揭示出价的实际价值的投标表示来验证,从而保持投标的保密性。 提供投标人与验证子系统之间的交换便利了验证拍卖是作为密封投标拍卖进行的。
