摘要
提出了一个新的(t,n)门限代理签名方案,安全性是基于离散对数和安全单向函数的.该方案结合了门限和代理签名的特性,对代理签名者实行了身份隐藏,并保证了匿名身份的可追查性;能够抵抗合谋攻击,保证了代理签名的不可否认性和不可冒充性,并实现了原始签名人安全地把委托信息传递给密钥管理中心.
Based on the security of the discrete logarithmic problem and the safe one-way function. This paper proposes a new （t, n） threshold proxy signature scheme which combines the characteristic of threshold and proxy signature. In this scheme, the proxy signers＇ identity is hidden, and traceable of anonymity is assure. Also, this scheme can resist the joint cheating, and insure the irreversibility and non-imitation.
