通信网络安全分层及关键技术

Network Security and Key Technology

通信网络安全除意识形态安全外,主要涉及信息传递安全、网络服务安全及承载网和业务网安全等层次。通信网络安全的关键技术大致包括安全性分析评估、网络拓扑设计,以及网络故障检测、保护倒换与故障恢复,此外,信息传递方面还包括加密、信息鉴别和签名以及密钥管理等。但网络安全问题的核心和瓶颈不是在于技术而是在于管理和投入。目前解决网络安全问题的大部分技术是存在的,但是如何把这些技术综合起来,还存在很多问题,需要继续进行理论上的研究和在试验环境下进行实际测试来验证,才能在一定程度上解决网络的安全问题。

Network security covers information security,service security and transport network security. The key technology of network security includes security evaluation,network topology design,network failure inspect,protection switch,failure resume etc. Other technology such as encryption,information authentication,signature and key management guarantee security of information transmission. The core of network security is management and investment. There's still many problems how to integrate technology together,which will be proven through research and test before implemented in network.
