摘要
椭圆曲线密码体制已经成为密码学的研究热点之一。相对于其它公钥密码体制,椭圆曲线密码体制有短密钥和计算效率高等优点。本文介绍椭圆曲线密码体制及其在加密和数字签名等方面的应用,并讨论了椭圆曲线密码体制的安全性。
Elliptic curve cryptosystem has become one of the hot spots of study. Compared with some other Public-key cryptosystems, Elliptic curve cryptosystem has many merits that can use smaller keys and computationally more efficient algorithms than traditional cryptographic algorithms. This paper introduces the Elliptic Curve Cryptosystem and its application in encryption and digital signatures, also discuss the Elliptic Curve Cryptosystem security.
