Access control models for pervasive computing environments
With the growing advancement of pervasive computing technologies, we are moving towards an era where context information will be necessary for access control. Traditional access control models like Mandatory Access Control (MAC), Discretionary Access Control (DAC), and Role-Based Access Control (RBAC) do not work well in this scenario for several reasons. First, unlike traditional applications, pervasive computing applications usually do not have well-defined security perimeter-the entities an application will interact with or the resources that will be accessed may not be known in advance. ...
