Rfid based security platform for internet of things in health care environment

Many Technology experts consider Internet of things as major step for the future endeavors that are going to happen in computer network field. According to CISCO, IoT can be considered as a situation or time where more things are connected to internet than human beings. Things represent the physical objects which are provided with unique identification numbers and their purpose is to collect and transmit the data which are relevant to the scenario in which things are placed. From building and home automation to wearable, the IoT touches every facet of our lives. Many corporates are making heavy investment in using IoT as a solution in Healthcare field. With help of intelligent systems one can obtain the life critical data from patients and by making appropriate use of these data improves the efficiency of health care industry. The data collected from patient is extremely sensitive so along with revolutionizing patient care proper security measures have to be taken to safeguard connected devices and networks in the Internet of things. The intelligent system includes different bio-medical sensors and the data collected using these sensors will be small in size and frequent in transmission, so the encryption technique to be followed should be of lightweight scheme. In modern world of cryptography the new protocols are moving away from RSA to Elliptic Curve. The wide acceptance of ECC is due to its light-weight computation nature. In order to implement the concept of IoT we can use many wireless technologies among them the core technology used in IoT deployments in the health care environment is Radio Frequency Identification. In RFID system, proper authentication has to be performed between RFID tags and RFID reader. In this paper describes a authentication scheme which performs authentication between RFID tag and RFID reader with help of a server which contains some pre shared information about tag and reader.
