Title:
Yao’s millionaires’ problem and public-key encryption without computational assumptions

Authors: Dima Grigoriev, Laszlo B. Kish, Vladimir Shpilrain

Abstract:

We offer efficient and practical solutions of Yao’s millionaires’ problem without using any one-way functions. Some of the solutions involve physical principles, while others are purely mathematical. One of our solutions (based on physical principles) yields a public-key encryption protocol secure against (passive) computationally unbounded adversary. In that protocol, the legitimate parties are not assumed to be computationally unbounded.
