Abstract
Today advancements in information technology have led to multi-user information systems of high complexity, where users can group, collaborate and share resources. The variety of such systems include a wide range of applications such as collaborative document sharing and editing, social networks, work flow management systems, mobile location based applications etc. As those systems continue to evolve, additional requirements arise which need to be met, such as context inclusion in access control decision making and security policies that support grouping, collaboration and sharing. To address this need, we are working on expanding C-TMAC, a security model that intrinsically supports grouping, collaboration and context awareness. In this perspective, we utilize the mathematical modeling language of Colored Petri Nets, along with the CPNtools, in order to represent and analyze the basic components of C-TMAC model.
