Abstract:
Authentication and key exchange protocol is vital to the operation of a secure control plane. An inefficiency in the CCITT X.509 protocol is identified and an improvement is proposed so that the extra protocol run is eliminated. This dissertation proposes that the open control model of devolving control from the network equipment offers greatest flexibility for the implementation of secure control functions. An instance of a open signalling based control architecture was outlined and a solution to the secure bootstrap process in such a distributed processing environment is presented. With this flexible and open control model, multiple secure control architectures are possible. This dissertation presents two control architectures which offer secure multicast services and anonymous communication services. The proposed secure ATM multicast control architecture seamlessly integrates naming, dynamic membership, access control and routing architecture with security protection for multipoint-to-multipoint communications. A key element of the architecture is the trusted multicast authority framework which assists group creation control and network access control with the use of the Membership Card. The previously proposed user plane protection mechanisms is also extended to handle multicast channel confidentiality and integrity protection, group key management and dynamic group key change. Anonymous communication is a useful network service of great potential. This dissertation shows how anonymous ATM communication can be built on the infrastructure of the ATM Forum P-NNI framework.
