Abstract

A method processes a session having a first session packet received by a current node in an IP network having a plurality of nodes. The plurality of nodes includes a next node, and the current node that communicates with the next node using a Layer 3 protocol. The method receives the first session packet, which has a digital signature, payload data, and meta-data, at the current node. The method uses the payload data and meta-data to produce validation information, and uses the digital signature to produce a comparator digital signature. Next, the method compares the validation information with the comparator digital signature. If the validation information does not match the comparator digital signature, then the method discards the first session packet. If there is a match, then the method digitally signs the first session packet, and routes the first session packet to the next node via the IP network.
