Title:
Repeated Games for Generating Randomness in Encryption
Authors: Kenji Yasunaga, Kosuke Yuzawa
Abstract:In encryption schemes, the sender may not generate randomness properly if generating randomness is costly, and the sender is not concerned about the security of a message. The problem was studied by the first author (2016), and was formalized in a game-theoretic framework. In this work, we construct an encryption scheme with an optimal round complexity on the basis of the mechanism of repeated games.
