Secret Sharing Scheme with Weighted Participants Based on Repeated Games
摘要
Abstract
In most secret sharing schemes with weighted participants, different amount of players' secret subshares can cause unfairness problem in the secret reconstruction phase. This paper proposes a rational secret sharing scheme based on repeated games. On the basis of original subshares, it constructs new subshares for each player, making sure that each two amount of subshares differ by a value at most 1. Through repeated games, every player can get all of other players' subshares and then reconstruct the secret. Analysis result shows that the scheme can make every rational player follow the secret reconstruction protocol all the time and be able to reconstruct the secret. And it has high security and expandability.关键词
