A Multiple LSPs Approach to Secure Data in MPLS Networks

Abstract

MPLS security is an evolving issue which has been raised by many researchers and service providers. The basic architecture of MPLS network does not provide security services such as encryption. Therefore, MPLS does not protect the confidentiality of data transmitted. This paper provides a mechanism to enhance the security in MPLS networks by proposing a modified (k, n) Threshold Secret Sharing scheme where the n shares obtained are send over multiple disjoint paths. We have implemented our approach to measure its time overhead on packet transmission.
