结合椭圆曲线上的Tate配对和混合加密体制,提出了一种新的签名加密算法,它集密钥交换、数字签名和数据加、解密功能于一体;针对短信息系统自身的特点,基于该算法提出了一种适用于短信息系统的加密方案,能完全抵抗生日攻击.既安全又实用。
Combined Tate pairing defined on elliptic curves with hybrid cryptosystem,a new signcryption algorithm is introduced in this paper.The algorithm aggregates key exchanging,signature verifying and data encrypting.Based on the signcryption algorithm and the properties of SMS(short message system),the paper puts forward a novel scheme for SMS encryption.The scheme also can fully resist birthday attack.h is secure and practical.
