Abstract

The temporal extensions of the Role-Based Access Control (RBAC) model imposes duration constraints on the availability of roles by allowing periodic enabling and disabling of roles. For deploying these models, a set of roles having associated time constraints are required. Such type of roles are termed as temporal roles and the process of creating them is referred to as Temporal Role Mining. In many real-life scenarios, simply imposing time constraints on role availability may not be sufficient. The system administrator may need to ensure different types of constraints reflecting specific organizational policies. In this paper, we propose a cardinality constraint which restricts the maximum number of temporal roles that a user can activate in a particular time interval. We name this constraint as Temporal Role Assignment Constraint (TRAC). We formally define the problem of mining a minimal set of temporal roles in presence of TRAC as the TRAC Temporal Role Mining Problem (TRAC-TRMP) and propose an algorithm for solving it. We also present the experimental results reflecting the performance of our proposed approach.
