Efficient Fine Grained Access Control for RFID Inter-Enterprise System

Access control management is a very challenging task in an inter-enterprise RFID system due to huge amounts of information about things or objects that can be collected and accessed to and from the system. Furthermore, the information stored in the inter-enterprise RFID system contains sensitive and confidential data related to the activities of the organization involved around the RFID system. Hence, the efficiency and high-granularity are critical in the design of access control for such system. This paper presents a novel access control model which is efficient and fine grained for such a system. A detail definition and mechanism of the access control model are described in the paper. A system implementation is developed for the evaluation purpose. An important performance measure in big data processing is delay in processing time, thus the evaluation aims at measuring the access control processing time. The evaluation results show that the model is consistent, and is able to achieve less delay than the inter-enterprise RFID system without access control at a certain point.
