| 内容記述 | Recently, a concept of bid-rigging is issued in an electronic auction. To prevent this attack, Abe-Suzuki proposed firstly a receipt-free scheme based on the bidding-booth. Chen-Lee- Kim pointed out that Abe-Suzuki ’s scheme only provides receipt-freeness for losing bidders. Also, they introduced a new receipt-free sealed bid auction scheme using the homomorphic encryption technique. The main participants of their scheme are Auctioneer, Auction Issuer, Bidder and Seller. We argue that it can be generated bid-rigging by a seller. Also, we propose a receipt-free sealed-bid auction which satisfies privacy, correctness, public verifiability, nonreputation and receipt-freeness. For privacy, correctness, public verifiability, non-reputation and receipt-freeness, we use Pseudo ID of a bidder and the universal re-encryption mix-net which is proposed by Golle et al. |
