Abstract
The invention that addresses the problem of authentication of the transport packet stream (which constitutes a flow within a session), which has been admitted into a managed packet network. Authentication and the subsequent policing of the flows supporting an identified client's authorized service prevent a large class of denial of service attacks described below. Specifically, the invention addresses two different matters: 1) key distribution and management 2) various forms of using a shared key for the authentication of transport packets on the user-to-network-interface (UNI).
