该文提出了一种高效的基于身份的代理签名方案。在计算效率方面,代理签名过程只需1次乘法运算和2次指数运算,验证阶段只需2次乘法运算,4次指数运算和1次双线性对运算。与现有的准模型下基于身份的代理签名方案相比,该方案的效率更高,提升近2/3。
An efficient ID-based proxy signature scheme(IBPS) is proposed.In computational cost,the proposed scheme only needs one scalar multiplication and two exponentiation in proxy signature phase and two scalar multiplication,four exponentiation and one pairing evaluations in verification phase.Compared with the other identity-based proxy signature scheme in the standard model,the scheme has the advantage of less operation.
