A Comparison of Lightweight Cryptographic Algorithms

Most IoT devices or WSN devices have limitations on memory, power, and energy consumption. Therefore, it is impossible to implement traditional cryptographic algorithms on these devices. This situation requires creating a “lightweight” type of cryptographic algorithm for these devices. This article analyzes existing lightweight cryptographic algorithms based on various factors: security, energy consumption, and hardware and software implementation. The analysis result showed the possibility of using current light cryptographic algorithms and the need to create new ones.
