Study on Lightweight Cryptographic Algorithms for IoT

Abstract

With the arrival of Internet of things, most of the current world applications are adopting IoT
concepts as it makes them modular, efficient and fast. However, IoT devices are interconnected
and persist across wider geographical locations; hence it coexists and leads to a greater security
risk. As a result of this, it is at most important to analyse the existing cryptographic ciphers on
such devices and decide if they are feasible in terms of execution time, memory consumption and
efficiency. The crucial elements which need to be addressed in IoT are Security and Privacy. In
the layered architecture, the available solutions for security are still vulnerable to attacks.
Therefore, in order to strengthen the security, lightweight cryptographic algorithms are used. In
this paper a comparative analysis is provided on existing lightweight cryptographic algorithms
which are used for providing security in IoT
