Abstract
We propose a new auction protocol scheme that uses the publicly verifiable secret sharing (PVSS) scheme. Unlike the existing scheme where a verifiable encryption scheme is employed when there is a dispute between a bidder and the auctioneer, the proposed scheme essentially removes the potential of a dispute. In addition, it has a robust registration phase and any entities participating in or observing the auction can verify the correctness of the auction process. The manager does not directly chooses the private key for the bidders, but only verifies the correctness between the private key and the public key, thereby improving the security, such as a bid submission of a malicious manager using the private key of a bidder.
