Abstract :
We have developed an electronic auction system with a set of distributed servers that collaborate to resolve a winning bid without revealing the secrecy of bids. This paper describes the system architecture and shows the performance in terms of the round complexity and the bandwidth consumption for a message. Based on the actual measurements, the upper bound of number of bidding prices is identified. In addition, by adding some steps to the basic auction protocol in Kikuchi, Harkavy, and Tygar, 1998, we improve the security of protocol so that the second highest bid must not be known even by the winner
