Shin Hyungsik, Ho Kyoung Lee, Ho‐Young Cha, Seo Weon Heo, Hyungtak Kim · 2019
Internet of things (IoT) has received much attention from many fields, and its applications are widespread in various domains. As many devices are connected to the Internet, the security issues arise and need to be addressed. In this paper, we review the challenges and the current status of IoT security technologies. Since most IoT devices operate on battery power or self-harvested energy sources, it is critical to reduce energy consumption for device operations. Therefore, we review some of light weight block cipher algorithms, which are one of the fundamental building blocks of countermeasures to cope with IoT security threats.
