—With the advances of network technology, electronic
auctions have become increasingly popular in recent years. In
2012, Xiong et al. proposed a bidder-anonymous auction scheme
based on revocable ring signature to enhance the computation
efficiency and provide a dispute protocol. Nevertheless, we find
that it has design weaknesses and is vulnerable to denial-of-service
attacks. Furthermore, in an actual electronic auction system
such as Yahoo! and eBay, a user can play the role of not only a
bidder, but also an auctioneer. Considering the essentiality of the
discussion of the secure products on-shelf process for auctioneers,
we design a new electronic auction system with a secure on-shelf
mechanism in this paper. In our system, users can freely participate in or host an auction if and only if they have registered at
the agent center. Analyses demonstrate that our auction system
not only resolves the problems in Xiong et al.’s scheme, but also
provides more features with higher security.
