| 摘 要： | 利用椭圆曲线上Weil配对的双线性性质和Euler准测，提出了一种基于双线性映射的签名加密方案．它不仅可以获得较快的加密解密速度，解决棘手的密钥管理问题，辨别消息的真伪，还能抵抗重发密文的攻击．该方案有效地降低了公钥证书的分发和管理成本，签名长度几乎是Guillou-Quisquater签名长度的1／4．

| Abstract: | A bilinear pairing signcryption scheme is proposed using the bilinear property of the Weil pairing defined on elliptic curves and Euler's criterion.The scheme not only can obtain the quicker velocity of encryption and decryption,solve the difficult problem of key management,distinguish the right message from the wrong message,but also can resist the attack which sends cryptograph continuously.The signature size is only about a quarter of the Guillou-Quisquater signature.The management and storage spending of the public key certificate could be efficiently cut down using this scheme. |
