Reliable radio frequency identification devices and secure routing in wireless medical systems

Huzaifa Al Nahas, University of Nebraska - Lincoln


Achieving high assurance in medicine using computerized systems is attracting increasing interest in the medical and computing fields. The emerging RFID technology is promising to achieve a significant enhancement in the safety and quality of health care. The dissertation consists of two parts. In Part I, motivated by the sensitivity of RFID systems in hospitals and the continuous sharp decrease in RFID cost, we develop Reliable Secure Radio Frequency Identification Medical System, or Miss–R2F. We develop two architectures: conceptual architecture that tolerates one active fault in the patient identification components, and 3 × 3 architecture that tolerates one active fault in any of its components. The conceptual architecture has three identification subsystems that perform dual passive RFID identification and an active RFID identification. The majority vote of the three subsystems is used in order to match pills with patients correctly. The system has a support subsystem that is responsible for confirmation and security. The support subsystem is triplicated in the 3 × 3 architecture. The main contributions of Part I is the architectural design and reliability analysis of Miss–R2F. ^ Part II of the dissertation focuses on security. We design security mechanisms for preserving patient privacy and protecting Miss–R 2F from intruders. In addition, we develop Secure-Path Routing (SPR) in wireless sensor networks. We develop energy-efficient centralized and distributed algorithms that direct more traffic over nodes that are less likely to be compromised, and therefore mitigate the impact of wormholes and sinkholes on routing security. Then we use this approach for enhancing routing security in Miss–R2F. The main contribution of Part II is the development of proactive mitigation algorithms for secure routing in wireless sensor networks.^
