Efficient Role Based Access Control Method in Wireless Environment

摘要

As resource sharing is common practice in distributed and wireless network, authentication and authorization become important issue in the security field. Many access control mechanisms including Role-Based Access Control (RBAC) are widely used for authorization. The common use of the wireless network imposes not only existing problems such as secure system management but also new problems such as limited storage and transaction size. In this paper, we propose an access control method that solves these problems for wireless environment. The proposed system uses bit pattern to represent access control information hence reduces transaction size and enhances security level. This system employs neural networks instead of access control tables, which reduces storages for role-permission tables and extra mutual exclusive data tables.
