Abstract
It is envisioned that asynchronous transfer mode (ATM) will provide
scalable and high-performance application-independent security services.
The ATM Forum Security Working Group is currently developing its phase one
security specification, which defines a number of security services for the
ATM user plane and control plane. In addition, mechanisms for carrying
security-related messages and required security infrastructure are being
defined. These mechanisms will allow an organization to build an ATM
network which not only meets its performance objectives, but also its
information protection requirements as specified in its site security policy.
This article provides an overview of ATM security as specified by the
ATM Forum Security Working Group. First, the ATM user and control planes'
security services and mechanisms are described. Then the security
messaging mechanisms at connectionn establishment and during connection
lifetime phases are discussed.
