椭圆曲线密码算法在VPN安全握手中的应用

Elliptic curve cryptographic algorithms in the application of VPN security handshake

深入分析了当前通用的基于RSA算法的安全套接层协议及其存在的缺点。基于椭圆曲线密码系统的优势,提出了加速点积运算椭圆曲线密码算法,使用ECC代替RSA改进SSL协议,缩短了密钥长度,使加解密耗时比RSA缩短了30%,从而达到了占用带宽小,连接速度快,同时又很安全的目的。

Further analysize the current general Secure Sockets Layer （SSL） protocol based on RSA algorithm, The disadvantages of the RSA ale pointed out. Based on the advantage of the elliptic curve cryptosystem, in this paper ,puts forward to accelerating the dot product operation of elliptic curve cryptographic algorithms, Through ECC instead of RSA in the SSL protocol, Shorten the length of the key and the time？by 30% in encryption and deception than RSA. So as to achieve small bandwidth, connection speed and security.
