支持AAA的MPLS VPN安全解决方案

An AAA of Security Solution for MPLS VPN

针对互联网情况下数据包在MPLS网络中传送时存在的安全威胁问题,在MPLS标签中增加了一个新的扩展头标,即AAA认证头标,并且给出了支持AAA的MPLS VPN网络结构,提出了一个引入AAA的MPLS VPN安全解决方案,从而确保了通信数据在传输过程中的安全性,相应的安全性分析和性能分析明确表明新提出的安全解决方案比以前的方案更加强健。

In allusion to existing security threat as Data packet is transmitted in the MPLS network, by making use of the new addition to AAA extension header named AAA signature authentication header in MPLS label and the MPLS VPN architecture supporting for AAA, an AAA security solution is presented in order to ensure the safety of communication data in the process of transmission.The appropriate security analysis and performance analysis of the new solutions clearly demonstrate that this authentication schemes are more robust than previous schemes.
