摘要
文章基于双线性对提出了一种新的无可信中心的门限签名体制。在多数环境中一个可信中心并不存在,所以没有可信中心的门限签名体制更受青睐,并且该协议几乎满足一个良好的门限签名体制的所有要求。该协议简单可行,在电子商务和电子投票中比其他协议更实用。
Based on bilinear paring, a new threshold signature scheme without a trusted party is proposed. Usually there is no such an authority which can be trusted by everyone, so the scheme is more attractive than the ones with a trusted dealer. Furthermore, the scheme satisfies almost all the requirements of a good threshold signature, and it is simple and efficient, thus is more applicable in electronic commerce and electronic voting than the previous ones
