Network Security Test Bed - Overview

� Linux based emulator with many of the DVB-S and DVB-RCS satellite

network functions including security:

� The testbed can be used for non-satellite networks as well

� Interfaced to Ethernet network and dedicated server

� A complete multicast security system has been demonstrated over

this testbed including:

� Group Secure Association Key Management Protocol (GSAKMP)

� Logical key hierarchy (LKH) for efficient key distribution in very large groups

� Unidirectional Link Encapsulation (ULE) security has been realised as

define in the IETF RFC 5458.

Potential Uses

� Trust management between security entities such as senders, receivers,

middle-boxes and security managers.

� Internet and future Internet security protocols (including Delay Tolerant

Networks, DTN).

� User identity hiding and anonymity.

� Key management for unicast, multicast and broadcast using centralised

and distributed security systems.

� Interworking between security, QoS and mobility.
