Improve Healthcare Safety Using Hash-Based Authentication Protocol for RFID Systems

Medication errors are now rapidly increasing that result in a serious impact on patients Safety. A lot of automated techniques have come up using the Radio-Frequency Identification (RFID) Technology that has now been successfully implemented in hospitals and healthcare institutions. The data that is being transmitted is highly sensitive and has to be authenticated between the server and the tag. Such a mutual authentication is highly necessary to enhance the safety protocols. An RFID authentication protocol using Elliptical Curve Cryptography could overcome security weaknesses and eventually lead to better performance. In order to achieve better security and quicker runtime, ECC must have smaller keys compared to non-ECC. In this paper, elliptic curves over a finite field are being structured that belongs to the category of publickey cryptography. This proposed protocol system not only increases the security to a greater extent but also enhances the performance by enabling large-scale implementations. As security is an instrumental aspect of cryptography, such a proposed system is effectual.
