AN ANALYSIS OF RFID AUTHENTICATION SCHEMES FOR INTERNET OF THINGS (IOT) IN HEALTHCARE ENVIRONMENT USING ELGAMAL ELLIPTIC CURVE CRYPTOSYSTEM
Publication Date : 29/03/2016
Internet of Things (IoT) has emerged as one of the most powerful communication paradigms of the 21st century. In the IoT environment, all objects in our daily life become part of the Internet because of their communication and computing capabilities (including microcontrollers, transceivers for digital communication, suitable protocol stacks) that allow them to communicate with other objects. In the healthcare area, IoT involves many kinds of cheap sensors (wearable, implanted, and environmental) that enable elderly people to enjoy medical healthcare anywhere, any time. Radio-frequency identification (RFID) is one of the most important technologies used in the IoT as it can store sensitive data, wireless communication with other objects, and identify/ track objects automatically. To satisfy the various security requirements of RFID technology in IoT, many RFID authentication schemes have been proposed in the past decade. Recently, ElGamal elliptic curve cryptography (EECC)-based RFID authentication schemes have attracted a lot of attention and have been used in the healthcare environment. In modified method, the number of doubling and adding operations in the encryption process has been reduced. The reduction of this number is a key point in the transformation of each character into an affine point on the EC.
