A Survey: Lightweight Cryptography Study for Healthcare Devices and Applications Within the Internet of Things

The Internet of things (IoT) is growing more prevalent and popular in recent years as a result of interconnected entities that allow millions of gadgets to talk with one another. We can call IoT an evolution of the Internet, and it has gotten. In recent years, there has been a lot of interest from researchers. The IoT is significant because it allows many low-resource and restricted devices to communicate, calculate, and process many operations and make decisions in the communication network. With each technological improvement, the creation of intelligent systems with high communication and data collection capabilities becomes achievable, opening up new opportunities for a wide range of IoT applications, notably healthcare systems. On the other hand, everything is useful and is not without problems and challenges. There are several difficulties to deploying IoT in the real world, ranging from tiny sensors to servers, such as interoperability, portability, accessibility, privacy, and information security. In this article, we present a complete survey of IoT technologies, processes, statistics, and success stories applied to healthcare, with an emphasis on the security threats and needs of IoT cryptography, technology, and IoT device trends.
