Technical Summary

This document provides a threat analysis and derives the security
requirements when using the Transport Stream, TS, to support an Internet
network-layer using the Unidirectional Lightweight Encapsulation
(ULE) defined in RFC4326. 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.

Working Group Summary

This document builds on RFC 4326, and identifies a set of
security-related topics that impact IP operation over a range of
broadcast links supporting IP.

Document Quality

The IPDVB WG has reached consensus that this document is ready for
publication as an informational RFC. This document does not define a
protocol or new mechanism.
