Secure and Reliable Data Delivery in MPLS VPN Based Networks

As Multiprotocol Label Switching (MPLS) is becoming a more widespread and developing technology for providing Traffic Engineering and high speed networking. Most of the internet service provider are deploying MPLS VPN technology for Enterprise Network, to provide Security and Quality of Service (QoS) guarantees to costumer sites . MPLS architecture security have been a increasing concern to Service providers (SPs) and VPN customers. MPLS has a security problem an attacker can successfully get into the core router of MPLS Backbone . In this paper, we propose a approach to enhance the confidentiality service in MPLS network. The idea is to divide a secret message into multiple shares by secret sharing and deliver them via multiple independent paths to the destination. The combination of the secure sharing Scheme and the Multipath routing technique results in a novel approach for enhancing reliable delivery of data in MPLS VPN network.
