Unified Link Layer Security Design for IP Encapsulation using Unidirectional Lightweight Encapsulation over Satellites

摘要

There is growing interest in providing multimedia and broadband access over satellites. However there are several technical challenges need to be addressed. One challenge is security in terms of understanding threats and providing an effective security system. Also this paper presents a ULE security solution using ULE mandatory extension headers. The design issues and choices are discussed. The detailed security header format is described together with processing sequence in both transmitter and receiver sides.
