Analysis and Research of Proxy Signature Protocols

摘要 在一个(t,n)门限代理签名体制中,原始签名者可以将他的签名权利以门限的方式委托给n个代理签名者,使得至少t个代理签名者合作可以代表他对消息签名,而至多t-1个代理签名人不能产生有效的代理签名。文中借助于RSA秘密共享的思想,构造了一个安全、有效的RSA门限代理签名方案。 In a (t , n ) threshold proxy signature scheme, the original signer delegates the power of signing messages to a designated proxy group of an members. Any t or more proxy signers of the group can cooperatively issue a proxy signature on behalf of the original signer, but t-1or less of them cannot do the same thing. Using the Threshold-RSA method, the authors construct a secure RSA-based threshold proxy signature scheme.
