Abstract
A method and system to increase security in VPN services are provided. The method comprises receiving, at a VPN terminator, a message sent by a first computer device at a first site intended for a second computer device at a second site; encrypting the received message, at the VPN terminator, using a first shared session key, the first shared session key being updated using a first renegotiated session key; and routing, by the VPN terminator, the encrypted message to the second computer device. The method further comprises periodically combining the first renegotiated session key with a first LLB shared secret to generate a first hash function, which is used to create the first shared session key. The first LLB shared secret is computed by hashing a value of at least one selected random seed with another LLB shared secret.
