Link layer security design for IPv6 over satellite DVB networks

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. This paper presents a security solution for the Unidirectional Lightweight Encapsulation (ULE). The security header extensions are presented together with detailed transmitter and receiver processing. Finally, the implementation of this solution is shown over the SATSIX project satellite emulator platform.
