Role-based access control in telecommunication service management—dynamic role creation and management in TINA service environment

Abstract

Security issues in telecommunication service management in Telecommunication Information Network Architecture (TINA) service environment is studied by using billing and Video on Demand (VoD) service session examples. Role-based access control is extended to address the needs of telecommunication service management. Security space represents session particpant’s security interests, and is a useful concept to describe separation of security interests in service session. To address the security issues of service composition and federation, algebraic role specification, strongly-roled system, and role mapping are studied.
