Attribute-Based Access Control using Combined Authentication Technologies

As NETWORK attackers become more and more sophisticated and wireless communications make the potential risks in data protection more serious, we come to need much stronger authentication and access control systems. In this paper we propose a combined authentication method including biometric and access control system based on attribute-wise encryption in wireless environment for ubiquitous computing era. It can accomplish both of the authentication of a user oneself and data retrieval by using one time padding in one round. Our access control method is flexible to dynamic policy or role changes.
