摘要： 密钥创建是以密码学为基数的数据保护的核心，同时也是Internet上对报文进行保护的关键。介绍了在Internet协议中两个通信实体利用Diffie-Hellman密钥交换技术协商创建密钥的几种方案，并就每种方案的特点进行了讨论。

Abstract: Key establishment is the heart of data protection that relies on cryptography, and it is an essential component of the packet protection mechanisms in many Internet security protocols. In this paper, we introduce some key negotiation schemes based on Diffie-Hellman key exchange technology. We also give some discussion on each of them.
