S-Box Implementation for Security Algorithms in IOT

Abstract

Internet of Things (IoT) is dominant technology for real time applications because it is integrated with various sensors, software and hardware. Security is the primary concern for IoT because of many ways of threats from different components. Typical encryption algorithms have less complexity and easy to decrypt thereby requiring high
complexity security algorithm. The improved security algorithm must be less in size and power hence compatible to IoT based applications. This paper is used an Elliptic Curve Cryptography (ECC) to generate Substitution box (S-box) hence proposing 128-bit block cipher based on feistel network.
