With the explosive growth of Internet of Things devices and massive data produced at the
edge of the network, the traditional centralized cloud computing model has come to a …

In this article we propose a standard for role-based access control (RBAC). Although RBAC
models have received broad support as a generalized approach to access control, and are …

Role-based access control (RBAC) models have generated a great interest in the security
community as a powerful and generalized approach to security management. In many …

We present a new approach to building secure systems. In our approach, which we call
Model Driven Security, designers specify system models along with their security …

Current day database applications, with large numbers of users, require fine-grained access
control mechanisms, at the level of individual tuples, not just entire relations/views, to control …

Delegation is the process whereby an active entity in a distributed environment authorizes
another entity to access resources. In today's distributed systems, a user often needs to act …

In this paper we present a context-aware RBAC (CARBAC) model for pervasive computing
applications. The design of this model has been guided by the context-based access control …

OASIS is a role-based access control architecture for achieving secure interoperation of
services in an open, distributed environment. The aim of OASIS is to allow autonomous …
