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.}, }
