摘要
通过对(t,n)门限秘密共享体制的研究,以及对RSA公钥加密体制的安全性和原理的系统分析,在费等(费如纯,王丽娜.软件学报,2003,14(1):146～150.)提出的方案基础上给出了一个确实可行的既能防止内部欺诈,又能防止外部欺诈的基于RSA的防欺诈的秘密共享体制.该体制的安全性等价于RSA,对该体制的欺诈等价于攻破RSA体制,同时有很高的信息率.
Through researching the (t,n) threshold secret sharing scheme and fully analyzing the security and theory of the RSA scheme, a secure and efficient cheat-proof secret sharing scheme has been proposed by means of the scheme presented by (R. C. Fei, L. N. Wang. J Sofware,2003,14(1):146～150.), which can resist internal and external cheats. The cheating on this scheme is equal to attacking RSA scheme. This scheme has a high information rate.
