Secure first-price sealed-bid auction scheme
2017
EURASIP Journal on Information Security
Preserved Fulltext
In this paper, we proposed a secure auction system, in which the bids will not be revealed, and no one can fake the winning identity and the winner cannot change the winning bid. ...
The communication cost of our scheme is low; only two rounds communication are needed between the bidders and the auctioneer. And we show that our scheme achieves the desired security requirements. ...
How to design the fair auction scheme with privacy preserving is an important research in modern auction system. ...

Thus, it is critical to protect bids from the auctioneer in an auction. With this goal, we develop a Privacy-Preserving Economic-Robust spectrum auction scheme, namely PPER. ...
However, most of them assume the auctioneer is trustful and do not protect users' interests. An auctioneer can manipulate the winner's charging price if it knows users' bids. ...
Then, a privacy-preserving auction scheme is proposed to protect the STs' bid privacy. ...

The main reason for constructing secure auction protocols is that the losing bids can be used in the future auctions as well as negotiations if they are not kept private. ...
We initially propose two secure second-price auction protocols with different masking methods. ...
This problem can be resolved by constructing privacy-preserving auction protocols. ...
