Lightweight block ciphers with applications in IoT

Abstract

This chapter aims to provide a comprehensive survey of lightweight block ciphers that have been designed for resource-constrained IoT platforms. The implementations of 10 lightweight block ciphers are compared on 8-bit, 16-bit, and 32-bit microcontrollers by using evaluation metrics such as power and energy consumption, latency, security level, throughput, and efficiency metrics. Furthermore, advantages and disadvantages of these ciphers are discussed. Finally, authentication problems and solutions for IoT devices are discussed in detail.
