Attribute Based Access Control and Security for Collaboration Environments

Abstract

Proliferation of collaboration environments brings new issues to the area of security. In this paper, we briefly describe the characteristics of security associated with collaboration environments. We also discuss and analyze several schemes in different areas of security, including access control, secure group communication, and security management. Another contribution of this paper is a proposed access control model with more flexibility and ability to address trust and privacy preserving issues based on attributes.
