Abstract

Methods and systems for enabling robust routing between protected enclaves over an unsecured network are provided herein. In one aspect, the present invention provides methods and systems for enabling routing among a plurality of protected enclaves, each supported by one or more secure gateways, over an unsecured network. Methods and systems according to the present invention achieve key routing requirements while presenting solutions that can be readily scaled to large network environments. In another aspect, the present invention provides methods and systems for implementing a Prefix Discovery Server (PDS) that enables the mapping of Plain Text (PT) networks to secure gateways, maintains current network routing information, and assists VPN gateways in determining routes to remote protected enclaves.
