摘要
在一种概率签名方案的基础上进行改进,构造了基于双线性对的门限代理签名方案.双线性对又称代数曲线W eil对和Tate对,是代数几何研究中一个很重要的工具.双线性对有很多优点,如签名较短等.并且对该方案进行了详细的性能分析,结论认为,该方案是一个高效的安全的门限代理签名方案.
Based on a probability signature scheme, a bilinear-pairing based threshold proxy signature scheme is proposed. Bilinear pairings, namely Weil pairings and Tate pairings, are rather important tools in algebra geometry. Bilinear pairings have lots of merits such as short signatures. And security of the scheme is analyzed. The scheme is secure and efficient.
