摘要
该文介绍了基于椭圆曲线密码体制的Diffie-Hellman密钥协商体制,以及存在的安全性问题,分析了主动攻击的方式,并提出了对这个密钥协商的一种改进体制.论述了改进后的密钥协商体制的安全性.
Elliptic Curve Cryptosystem is a hot spots in public key cryptography study. Based on Elliptic Curve Cryptosystem Diffie - Hellman key consultation system, we analyze the existence of the security issues. The results show that it is susceptible to active attacks, we analyze this active attacks, then make this key consultation system improved. At last we analyze the security of key improved consultation system.
