In this paper, we study the maintenance of role-based access control (RBAC) models in database environments using transitive closure relations. In particular, the algorithms that ...
The role-based access control (RBAC) has significantly simplified the management of users and permissions in computing systems. In dynamic environments, systems are usually unde...
Abstract-- Image computation is the core operation for optimization and formal verification of sequential systems like controllers or protocols. State exploration techniques based ...
This paper retrospectively analyzes the progress of event-based capability and their applicability in various domains. Although research on event-based approaches started in a hum...
Both the logic and the stochastic analysis of discrete-state systems are hindered by the combinatorial growth of the state space underlying a high-level model. In this work, we con...
