授权子集的群签名方案

A much secrete authorized subset signature scheme

基于有限域上的方程根提出一个新的授权子集的签名方案,参与者的签名通过方程根的性质验证,而与现有方案比较,该方案具有秘密计算复杂度低,所需公共信息量小的优点。方案的安全性是基于双线性对的DH问题的困难性。分析表明文中的方案是一个安全、有效的方案。

This paper based on the equation root in a finite field, put forward a new license subsets of signature scheme, the signature of the participants through equation root of the nature of the verification, and compared with the existing scheme, the scheme has a secret low computational complexity, the advantages of low information public. The safety of the scheme is based on bilinear pairings of the difficulty of the DH problems. The analysis shows that the scheme is a safe, effective solution.
