【摘要】 给出一个安全性基于LUC密码体制的广义秘密共享方案,其中,每个参与者的私钥即为其子秘密,在秘密分发者和参与者之间不需要维护一条安全信道,降低了系统的代价。秘密恢复过程中,每位参与者都能够验证其他参与者是否进行了欺骗,并且只需维护一个子秘密,就可以实现对多个秘密的共享。更多还原

【Abstract】 A general secret sharing scheme based on the LUC cryptosystem is proposed.In this scheme,each participant’s private key is used as his secret share,and the secret dealer needn’t distribute each participant’s secret share.In recovery phase,each participant is allowed to check whether another participant provides the true information or not.Each participant can share many secrets with other participants by holding only one shadow.更多还原
