Over the recent years, several smart applications like RFID's, sensor networks, including industrial systems, critical infrastructures, private and public spaces as well as portable and wearable applications in which highly constrained devices are interconnected, typically communicating wirelessly with one another, working in concert to accomplish some task. Advanced safety and security mechanisms can be very important in all of these areas. Lightweight cryptography enables secure and efficient communication between networked smart objects. The CLEFIA algorithm is a suitable lightweight cryptographic algorithm used in medium security systems. In order to increase safety and security mechanisms, modify CLEFIA are proposed which uses the Linear Feedback Shift Register (LFSR) to overcome the security weakness of the CLEFIA algorithm against attacks. In this paper an implementation of modify CLEFIA algorithm using C++ programming language. We have also compared the results with the standard CLEFIA.
