A new RFID ultra-lightweight authentication protocol for medical privacy protection in smart living


The widespread application of Radio Frequency Identification (RFID) technology in smart living, especially in smart healthcare, has greatly facilitated patient management, reduced the labor cost of medical services, and provided patients with better medical services. However, improper use of RFID tags is highly likely to threaten the safety and privacy of hospitals and even patients, which may not only cause physical and mental harm to patients but also damage the reputation of hospitals. Medical monitoring system based on RFID technology plays a significant role in guaranteeing the security of medical records as well as the privacy of patients. Nevertheless, due to the resource constraint of RFID tags/readers, it is also challenging to design an efficient and effective authentication protocol for RFID medical monitoring system. Aiming to reduce the resource overhead and meet security requirements of the RFID system, in this paper, we propose an ultra-lightweight RFID security authentication protocol utilizing a cloud server named CRUSAP, which is based on Bit-Crossing XOR rearrangement operations that can effectively resist forgery attacks, replay attacks, desynchronization attacks, and denial of service attacks while certifying the cloud server. The formal logic of BAN proves the safety and feasibility of the protocol. Additionally, the security analysis and experimental results show that the proposed authentication protocol can realize higher security goals at a lower cost and is more suitable for scaling to large-scale authentication.
