| Abstract: | 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. |
