Abstract: This paper proposes an efficient receipt-free sealed-bid auction scheme. It enjoys the property of receipt-freeness, which means that there is no information known to the coercer/buyer that could be used for the bidder to prove his bidding price. Thus the scheme is free from the bid rigging by the coercer/buyer. Compared with the existing receipt-free sealed-bid auction scheme in the literature, the scheme is more efficient when the bidding price range is very large.
