Systematic Review of Lightweight Cryptographic Algorithms

The emergence of small computing devices and the integration of processing units into everyday objects has made lightweight cryptography an essential part of the security landscape. Conventional cryptographic algorithms such as AES, RSA, and DES are unsuitable for resource-constrained devices due to limited processing power, memory, and battery. This paper provides a systematic review of lightweight cryptographic algorithms and the appropriateness of different algorithms in different areas such as IoT, RFID, and wireless sensor networks. Using tabular analysis and graphical interpretation, we compare these algorithms in terms of performance, security, energy consumption, and implementation costs. An overview of the evolution of lightweight cryptography based on those design trade-offs is also provided.

A Comparative Analysis of Lightweight Hash Functions Using AVR ATXMega128 and ChipWhisperer

Lightweight hash functions have become important building blocks for security in embedded and IoT systems. A plethora of algorithms have been proposed and standardized, providing a wide range of performance trade-off options for developers to choose from. This paper presents a comparative analysis of 22 key software-based lightweight hash functions, including the finalist from the SHA-3 competition. We use a novel benchmark methodology that combines an AVR ATXMega128 microcontroller with the ChipWhisperer cryptanalysis platform and evaluate and compare the various hash functions along several dimensions, including execution speed, % measured in Cycles per Byte (CpB), memory footprint, and energy consumption. Using the composite E-RANK metric, we provide new insight into the various trade-offs each hash function offers to system developers.
