摘　　要：利用椭圆曲线GDH群上的双线性,构建了一种基于身份的三方弱型签密协议,提供密文鉴别、报文机密、签名非否认等安全特性,摆脱了PKI体系的约束,提高了计算效率,为在线交易和支付提供一种安全高效的一体化解决方案。Using the bilinear property of pairing on the elliptic GDH group,a 3- party weak signcryption scheme based on ID is propose＆ It getts ride of the restriction of PKI system and surpasses the traditional one to one identification model having the securities such as cyphertext identification, message confidentiality, signature nonrepudiation, with high efficiency of computation, thereby providing a kind of integration solution for the online transaction and payment.
