Network Working Group M. Richardson Internet-Draft SSW Intended status: Informational December 18, 2013 Expires: June 21, 2014 security architecture for 6top: requirements and structure draft-richardson-6tisch-security-architecture-00 Abstract This document details minimal layer-2 requirements for 6top use in industrial settings, and a few options for accomplishing this. The layer-2 mechanism is then extended to provide for per-node authentication and authorization of the node/PCE communications. This internet-draft is intended for later inclusion into the 6tisch architecture document.
