华为设备上的安全技术总结之ipsec

发布时间:2020-07-13 19:58:47 来源:网络 阅读:340 作者:落寞小小 栏目:安全技术

ipsec

I IPSec 是一系列网络安全协议的总称,它是由IETF(Internet 工程任务组)开发的,可为通讯双方提供访问控制、无连接的完整性、数据来源认证、反重放、加密以及对数据流分类加密等服务。它是网络层的安全机制,通过对网络层包信息的保护,上层应用程序即使没有实现安全性,也能够自动从网络层提供的安全性中获益。这打消了人们对×××安全性的顾虑,使得××× 得以广泛应用。IPSec的工作方式有两种;传输方式;隧道方式。而且ipsec的工作模式有两种 手动配置 和自动协商

【实验目的】

 运用ipsec 的一系列网络协议建立×××管道模式保证信息的安全
