Abstract

With the rapid updating of Internet technology, electronic auction network environment is more complex,
so the electronic auction security requirements are getting higher and higher. In addition, the
study of multi-attribute auction research on security is still very lacking. In this paper, a secure multiattribute
reverse auction scheme is proposed. It uses the paillier threshold homomorphic cryptosystem
and multiple servers to prevent conspiracy attack between buyer and auction servers. Moreover,
the techniques of oblivious transfer and anonymization are also used to achieve the bidder privacy
and anonymity. Finally, the scheme achieves the public verification of auction process and auction
results and the security analysis is given.
