Abstract
In this paper we identify and address the challenges unique to providing a
secure ATM network. We analyse the network environment and consider the
correct placement of security mechanisms, with particular attention to
data transfer protection, in such an environment. We then introduce and
describe a key agile cryptographic device for ATM networks. We present
the techniques to provide data confidentiality, synchronisation, dynamic key
change, dynamic initialisation vector change, data integrity and replay '
protection on ATM data transfer. Finally, we discuss the corresponding
control functions for setting up such a secure channel. We examine the
impact of key exchange protocols on the design of ATM signalling
protocols. Our efforts in providing novel security services in ATM signalling
systems has also been presented.
