Performance analysis of security algorithms for IoT devices

Abstract

Internet of things (IoT) has gained tremendous attention in today's world, IoT ecosystem is growing and showing us a glimpse of how the future will look in the coming days. However, the IoT sector is not impeccable, security is still a threat for the IoT devices as these devices are meant for low power usage for small scale setups. Security algorithms are not abrupt, but many of them don't fit the IoT systems as their compatibility can only rely on products with larger form factor (Which usually means better performance, storage etc.). In this paper, the main concern has been to investigate the performance of different security algorithms and compare them in terms of processing cycle and execution timein Raspberry Pi. The paper has worked with FLECC_IN_C and Crypto++®, two different cryptographic libraries and measured their performance in a constrained environment. It is the first of its kind, to this paper's knowledge, to use raspberry pi which is established as black box device and implemented security algorithms on it. The paper in the end shows a summarised view of several key algorithms and decides which is better in the terms of IoT constraints.
