Ensuring secure and authorized access to remote services and information resources in a dynamic collaborative environment is a challenging task. Two major issues that need to be addressed in this regard are: specification of access control requirements and trust management. Specification of access control requirements for dynamic collaboration is challenging mainly because of the limited or lack of knowledge about remote users' identities and affiliations. The access control policies and constraints defining users' authorization over remote resources and services need to be specified in terms of the attributes and properties of the users. Moreover, the criteria for validating the attributes of the users should also be specified as part of access control requirements. Trust management, in the context of dynamic collaboration, involves validation of user's attributes for secure interaction and prevention of unauthorized disclosure of policies and attributes. The paper discusses these issues in detail and presents a framework for access control and trust management in a distributed collaborative environment.
