Abstract
The Unidirectional Lightweight Encapsulation (ULE) protocol has been defined for efficient transport of IPv4/6 and other protocols over the MPEG-2 Transport Stream (TS). The proliferation of this technology on the mass market may benefit from a security solution protecting against potential threats such as eavesdropping, as well as masquerading, modification of messages, and replay attacks, similar to 802.11 security. A unified ULE security extension header format has been proposed previously by the authors. This paper discusses in detail the processing required for transmitters and receivers supporting this security extension for ULE.
