Abstract
Asynchonous Transfer Mode (ATM), which can provide integrated services of
various media types and bit rates, is rapidly becoming the dominant
technology for local and wide area information transport. In this paper
we present a network security architecture for secure data transfer in ATM
networks. The proposed architecture facilitaes seamless integration of
security services into the existing ATM architecture and confirms to the
ATM B-ISDN PRM: security related signaling functionality, such as mutual end
system authentication, establishment of security associations, and cryptographic
key distributions are carried out in the control plane, while protection of
traffic is achieved by defining a Data Protection Layer in the user plane.
