Lightweight Security Algorithm For Wireless Node Connected with IoT

Objective: The enhancement of wireless technology and sensory device has brought to the introduction towards IoT (Internet of Things). Here security is taken as one of the major issues, as they operate in unlicensed bandwidth. Since most of the device is resource constrained the lightweight security is driven to these devices. Implementation of security is also tedious and selective as the conventional security algorithm degrades the network performance due to the high computational complexity and inherent delays that are incurred for execution of these algorithms. Method: In this work, a novel approach is made with new hybrid lightweight security algorithm named PRESENT-GRP which is derived in Intel Galileo Gen 2 board. This methodology helps to secure data during transmission and control process. Findings: This hybrid algorithm is an enhancement of the GRP permutation algorithm because it lags an S-box. This proposed algorithm is for low power devices which consumes relatively less memory. Thus, in Internet of Things (IoT) applications this algorithm may help to provide end to end privacy to share data securely. Improvement: In future works, this algorithm can be improved with still more security level by having a trade off between performance and memory usage. It can also be enhanced by implementing it in real time military related and health related applications for end to end security for smaller size datum.
