.... provide parameterisation; early examples include [1, 9, 10, 12] This trend has been further reinforced by the 2 specific parameterised models present in the NIST RBAC standards [15] Equally, many researchers have examined how to include dynamic environmental interaction in their RBAC models [1, 5, 6, 11]. Note that some authors refer to the dynamic environment as context , using the word in a different sense from this paper. One common motivation for such environmental interaction support comes from a desire to enforce dynamic separation of duties (SoD) constraints within role hierarchies. For ....

....provides dynamic access control to users, applications, services,components and resources. The engine is composed of access control agents associated with various entities in the system. The underlying dynamic role based access control mechanism extends the RBAC (Role Based Access Control) model[4, 5, 6, 29] to make access control decision based on dynamic context information. The access control engine dynamically adjusts Role Assignments and Permission Assignments as illustrated in Figure 7. Figure 7: Dynamic Access Control Model The subject is the entity which requests service from another ....

We plan to have more details about the implementation and performance of our system in the camera ready version of this paper. 8. Related Work Covington et al. [14, 15] tackled the problem of securing a smart home environment. They refer to this environment as the Aware Home. In their work, Covington et al. extend the RBAC access control model to develop a non intrusive access control system that can make use of environmental and contextual information. The ....

....operation through a heartbeat mechanism. Cooperating components cyclically attempt message exchanges within bounded time periods, assuring these components the OASIS service network is operating reliably. Recent research into RBAC increasingly discusses the need of contextawareness for roles [4]. OASIS supports context aware behaviour in two main ways. Firstly OASIS roles may carry parameters. Secondly environmental predicates, which are also parameterised, may be included in OASIS rules. These predicates provide a mechanism through which OASIS rules may depend on local system factors ....

....which are aware of the context of an ongoing activity. Bertino et al. BBF00] describe how temporal constraints can be defined for roles, for example, when a role is activated for a shift, and then subsequently deactivated. In addition, an administrator can activate roles ad hoc. Covington et al. [CLSDAA01] have explored applications for the home and suggest how environmental roles could be useful. Access can be permitted based on environmental factors, such as location or time of day. Georgiadis et al. GMPT01] combine contextual information with team based access control. Team based roles ....

....rules can have a membership flag that specifies that the new role should be deactivated if the condition should become false. In particular, the role may be deactivated if the user is no longer active in a prerequisite role. Recent research into RBAC has recognized the need for context awareness [3, 9]. This has been supported since the first version of OASIS by means of role parameters and simple environmental constraints in role activation rules. Role parameters and variables in environmental constraints are strongly typed in OASIS. Role activation rules have the form: r 1 ; r 2 ; r nr ....
