A New Approach to Enhance Security in MPLS Network

As MultiProtocol Label Switching (MPLS) is becoming a more widespread technology for providing Virtual Private Network (VPN) services, MPLS architecture security is of increasing concern to Service Providers (SPs) and VPN customers. MPLS suffers from a number of security issues as soon as an attacker successfully penetrates the core. This paper provides an approach to enhance security in MPLS network by integrating a new (k,n) Threshold Secret Sharing scheme with MPLS in which shares obtained are send over multiple disjoint paths. The authors' approach is implemented to measure time overhead on secrets packet transmission.
