This article primarily focuses on improving an existing symmetric key lightweight cipher known as Shadow. The growing importance of internet of things (IoT) networks and the consequential need for lightweight cryptography is highlighted. Various ciphers from the current literature are reviewed, and the strengths and weaknesses of the most efficient ciphers and those of Shadow are analysed. Our findings are used to modify the subkey generation algorithm of Shadow and thus create Shakey. Experiments are conducted to determine the avalanche effect and throughput of Shakey. Cryptanalysis is also performed to gauge its security. Finally, the structural advantages of Shakey and its improvement in performance with respect to Shadow is discussed. The article concludes with an outline for the future scope of this work and our closing remarks |
