Analysis and implementation of secure lightweight crypto algorithm

Abstract

Recent advancement in cryptographic technologies is being newlineextensively studied because of their focus on new techniques for design, newlineimplementation and attacks. One such advancement is Lightweight newlineCryptography (LWC) where the crypto algorithm is designed in such a newlinemanner that it can be implemented in any constrained environment. This newlineresearch work is an extensive study of an asymmetric LWC algorithm called newlineElliptic Curve Cryptography (ECC). This crypto algorithm operates over newlineelliptic curves and can be used in key exchange as well as a digital signature newlinefor authentication. In this work, the implementation, analysis, optimization newlineand security aspects of the crypto algorithm are presented. Since elliptic curve newlinealgorithms are lightweight, they can be used in the Internet of Things (IoT) newlinelike RFIDs, Vehicle On-Board Units (OBU) etc. newlineThe work starts with a basic introduction to cryptography and the newlineimportance of lightweight cryptography. The significance of elliptic curve newlinecryptography is given and the mathematical background behind the crypto newlinealgorithm is discussed. An extensive survey of the various literature works newlinethat focus on different aspects of ECC was done and the detailed study helps newlinein narrowing down the area of the research work. This is followed by the newlineimplementation of asymmetric crypto algorithms to study their performance newlineanalysis and how ECC outperforms the other crypto algorithms to fit newlinelightweight applications. The implementation is then analysed and several newlineoptimization techniques have been studied. Then the multiplier used in the newlineECC crypto algorithm is studied followed by selecting an efficient multiplier. newline
