摘要
IPv6在安全性上比IPv4有了明显的提高,但不能很好地保证应用层和协议本身的安全性。IPSec是网络层的安全协议标准,它提供了IP层上多种安全服务,其隧道模式为VPN的实现提供了必要的安全保障,VPN也为网关之间的通信提供了安全隧道。通过介绍IPv6校园网研究现状,分析了IPv6带来的安全问题,描述了IPSec网络层安全协议标准以及VPN技术的基本原理,详细阐述了IPSec VPN的优越性以及如何在IPv6校园网中进行安全部署,并指出了可能存在的不足以及进一步改进的方向。
IPv6 is more safer than IPv4,but it could not assure the security of application layer and the protocol.IPSec is security protocol standard of network layer,it offers several security services on IP layer.Its tunnel mode provides essential safeguard for the implementation of VPN,and VPN also affords safe tunnel for communication between gateway.The research areas of IPv6 campus network is introduced,and the security problems of IPv6 are analyzed.The IPSec security protocol standard of network layer and basic theory of VPN technology are described,and the advantages of IPSec VPN and how to deploy safety based on IPv6 campus network are discussed.Based on the potential disadvantages,the development directions are expressed.
