Security Requirements for the Unidirectional Lightweight Encapsulation Protocol
RFC 5458, “Security Requirements for the Unidirectional Lightweight Encapsulation Protocol”, is an Informational document published in March 2009 by H. Cruickshank, P. Pillai, M. Noisternig, S. Iyengar. The canonical text is published by the RFC Editor.
Abstract
The MPEG-2 standard defined by ISO 13818-1 supports a range of transmission methods for a variety of services. This document provides a threat analysis and derives the security requirements when using the Transport Stream, TS, to support an Internet network-layer using Unidirectional Lightweight Encapsulation (ULE) defined in RFC 4326. The document also provides the motivation for link-layer security for a ULE Stream. A ULE Stream may be used to send IPv4 packets, IPv6 packets, and other Protocol Data Units (PDUs) to an arbitrarily large number of Receivers supporting unicast and/or multicast transmission.
The analysis also describes applicability to the Generic Stream Encapsulation (GSE) defined by the Digital Video Broadcasting (DVB) Project. This memo provides information for the Internet community.
