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.
