| 摘 要： | 最近人们给以基于博弈的密码算法越来越多的关注.本文的目标是基于博弈论分析密码共享的秘密重构协议.分析表明在秘密重构协议中,先提供子密钥的局中人就要"吃亏",无论是在传统意义上的秘密共享体制,还是理性秘密共享体制都存在该问题.我们从信息熵的角度分析和证明了该问题,同时讨论问题的解决方法.

| Abstract: | Cryptographic scheme in a game-theoretic sense has recently gained much attention. The goal of this paper is game-theoretic analysis for the reconstruction protocol in the secret sharing scheme in detail. Analysis shows that there exists a problem that the first person pools its shares may suffer losses.Analysis and proof of the problem are made with information entropy and resolving method is given. |
