Bid-rigging is a dangerous attack in electronic auction. Abe and Suzuki firstly introduced the idea of receipt-free to prevent this attack. In this paper we point out that Abe and Suzuki’s scheme only provides receipt-freeness for losing bidders. We argue that it is more important to provide receipt-freeness for winners and propose a new receipt-free sealed bid auction scheme using the homomorphic encryption technique. In contrast to Abe and Suzuki’s scheme, our scheme satisfies privacy… CONTINUE READING
