An Analysis of Lightweight Cryptographic Algorithms for IoT-Applications

With the arrival of advanced technologies, IoT has enabled the connection of many devices that can collect huge amounts of data. IoT security requirements are therefore supreme. Cryptography is used to secure the confidentiality, data integrity, authentication and control access to networks. To provide a complete overview of this field, we have compared some existing algorithms based on hardware and software performance and expectations of different attacks. We also discussed the requirement and direction of novel research in lightweight cryptography to improve security and performance. This paper presents the performance comparison of their memory, latency & throughput, Area (GE), Key & Block size and other parameters of hardware and software efficient LWC algorithm. Primarily for lightweight block ciphers and further shows new research directions for developing new algorithms with the performance, security, and cost characteristics.
