| 摘 要： | 将离散对数、EIGamal体制应用到秘密共享体制,并与随机分配协议相结合,提出了一种可区分秘密分享者角色的秘密共享方案,此种方案有实际的应用背景.对秘密共享体制中的防欺诈措施进行了研究,对该方案的欺诈等价于攻击离散对数,而离散对数是单向函数,因而可以认为本方案是安全的.

| Abstract: | The discrete logarithmand the EIGamal scheme are applied to secret sharing scheme,which,together withthe randomdistribution protocol,lead to a secret-sharing scheme capable of differentiating the roles of the sharers.This scheme is quite practical.The cheating-proof method in the secret-sharing scheme is studied and it is deemedthat it is difficult to break the discrete logarithm,a one-way function,so the scheme proposed is secure. |
