A survey and analysis of different lightweight block cipher techniques for resource-constrained devices

Many smart applications are equipped with resource constrained devices which are characterised by small computational power, limited battery power and memory. Lightweight ciphers have become a popular choice for providing security for these devices. This work aimed to evaluate the performance and security of three lightweight ciphers called Anu, LiCi and Present. The performance of the ciphers is reported in terms of throughput. Data compression techniques are applied to improve the speed and throughput of the encryption. The efficacy of the ciphers in defending statistical attacks and differential attacks are assessed with the help of statistical and sensitivity tests. Our results proved that LiCi outperforms Anu and Present in many aspects.
