Interleaving Cryptography and Mechanism Design: The Case of Online Auctions

Edith Elkind and Helger Lipmaa

Abstract: We propose a new cryptographically protected multi-round auction mechanism for online auctions. This auction mechanism is designed to provide (in this order) security, cognitive convenience, and round-effectiveness. One can vary internal parameters of the mechanism to trade off bid privacy and cognitive costs, or cognitive costs and the number of rounds. We are aware of no previous work that interleaves cryptography explicitly with the mechanism design.

Category / Keywords: auctions, cognitive costs, cryptography, mechanism design, privacy
