Scalable, efficient, and secure RFID with elliptic curve cryptosystem for Internet of Things in healthcare environment

Abstract

The rapid development of IoT technology has led to the usage of various devices in our daily life. Along with the ever-increasing rise of the Internet of Things, the use of appropriate methods for establishing secure communications in health care systems is vital. The adoption of high-security optimal mechanisms for this purpose has been more effective regarding the efficiency of medical information systems; hence, many studies are being conducted in this field today. One of the most important components is the RFID cards that can be used for communication between entities in the environment. In healthcare systems, patient information is critical and nobody should have access to this information. Thus, providing security for these networks is essential. Recently, good researches have been done in the area of authentication for medical information systems, using RFID technology, which has a low computational cost. In this paper, we propose a novel method based on elliptic curve cryptography for vital and efficient and scalable authentication between RFID cards, card readers, and servers. This proposed method maintains security and has less computational cost and low elliptic curve point multiplication running time compared to similar recent methods.
