Securing virtual private LAN service by efficient key management
Madhusanka Liyanage, Andrei Gurtov · Security and Communication Networks · 2013
Virtual private local area network service VPLS is a layer 2 service provider-provisioned virtual private network service. Security is one of the key system requirements of a VPLS because it delivers the frames via an untrusted network. Several VPLS architectures are proposed during the recent years. However, many of them do not provide a sufficient level of security. On the other hand, the existing secure VPLS architectures are also suffering from the scalability issues, and they are infeasible to implement in large scale networks.
