DIBPresent: A Dynamic Integer Based LightWeight Cryptography for Resource Constrained Devices

Abstract

 Lightweight cryptography (LWC) is a modern cryptography algorithm which is designed to suit for resource constrained devices and Internet of Things (IoT) environment. IoT is an emerging technology and also next generation network in which, each device or node like smart gadget has limited capabilities such as short memory, low processing speed, minimum transmission range, etc. These devices are able to establish the connection for sharing information among the devices. The whole IoT environments, from manufacturers to users, still have many security challenges including in secured transfer of data.  One of the main challenges for deploying security mechanisms over IoT is to minimize the conflict between resource consumption and the desired security.   Due to resource constrained devices, Light weight cryptographic algorithms are ideal for IoT scenario. In this paper we presents new lightweight block cipher algorithm. DIBPresent cipher and studied its performance with different scenario such as changing key size and data block size.
