Types of Lightweight Cryptographies in Current Developments for Resource Constrained Machine Type Communication Devices: Challenges and Opportunities

Abstract

Machine-type communication devices have become a vital part of the autonomous industrial internet of things and industry 4.0. These autonomous resource-constrained devices share sensitive data, and are primarily acquired for automation and to operate consistently in remote environments under severe conditions. The requirements to secure the sensitive data shared between these devices consist of a resilient encryption technique with affordable operational costs. Consequently, devices, data, and networks are made secure by adopting a lightweight cryptosystem that should achieve robust security with sufficient computational and communication costs and counter modern security threats. This paper offers in-depth studies on different types and techniques of hardware and software-based lightweight cryptographies for machine-type communication devices in machine-to-machine communication networks.

AES Otimizado para Uso em Aplicações IoT

“…Há uma imensa demanda por algoritmos de criptografia leves que sejam confiáveis e que tenham um bom custo-benefício. É muito mais eficiente aprimorar a seguranc ¸a através de algoritmo criptográficos de baixo consumo do que substituir os dispositivos por algo com maior poder computacional [7]. Dos algoritmos criptográficos de chave simétrica, o AES é até hoje uma interessante soluc ¸ão de seguranc ¸a, já tendo sido amplamente testado por agências governamentais e pela comunidade acadêmica.…”
