摘要
基于Williams体制提出了一个具有完善保密性的秘密分享方案,该方案不需要安全传输信道,可在时效内防止密码分析员的攻击,且能防止来自各方的欺骗行为。秘密分享者能在多项式时间内恢复密钥,以便快捷地发出指令,有效解决了安全处理一些关键事务的紧急问题。
A secret sharing scheme based on Williams scheme is proposed which can transmute shares in an entrusted way. This scheme can prevent adversaries from getting the secret or shares and the participants cheating each other efficiently. By use of the scheme shares can get the secret in a polynomial time so that set orders quickly.and solve some critical questions safely and efficiently.
