A new Request for Comments is now available in online RFC libraries. RFC 5458 Title: Security Requirements for the Unidirectional Lightweight Encapsulation (ULE) Protocol Author: H. Cruickshank, P. Pillai, M. Noisternig, S. Iyengar Status: Informational Date: March 2009 Mailbox: h.cruickshank@surrey.ac.uk, p.pillai@bradford.ac.uk, mnoist@cosy.sbg.ac.at, sunil.iyengar@logica.com Pages: 26 Characters: 58733 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-ipdvb-sec-req-09.txt URL: http://www.rfc-editor.org/rfc/rfc5458.txt 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.
