IPSec安全网卡上消息认证模块的FPGA实现

Implement Message Authentication Module on IPSec Security Net Card Using FPGA

首先对IPSec安全网卡的整体框架,以及其中的IPSec模块和消息认证模块的结构框图作简要介绍,然后详细阐述了常用消息认证算法HMAC-MD5和HMAC-SHA1的硬件实现,得到综合与仿真的结果。最后通过对两个算法实现的分析比较,总结出提高运行速度的方法。

In this article,firstly,several modules including IPSec security net card,IPSec chip and the message authentication algorithm are presented.And then the paper,demonstates how to research and implement the HMAC-MD5 and HMAC-SHA1 algorithm individually in hardware,and issues the results after synthesis and simulation.At the end,with analysis and comparison for these two algorithms,the ways to speed up are concluded.
