        abstract = {Internet of Things (IoT) networks fuse software, sensors, and other devices to automate data collection and processing. Smart devices and industrial automation tools are examples of IoT systems that are rapidly changing business and everyday life. Healthcare, transportation, smart cities, and other systems also employ IoT networks. Because these networks facilitate mass data collection and processing, they raise concerns around invasion of privacy and the security of data transmitted. They also raise concerns about the integrity of that data and user authentication. IoT devices like RFID and other embedded systems are limited in resources and power, and they do not support cryptography. In these instances, a number of attacks on the network are possible, such as replay attacks, tracking, system denials, and various other attacks. In this paper, IoT systems and networks of various attacks are reviewed. Also, privacy concerns of IoT networks and system protection measures that support current security technology are examined. Lightweight, authentication methods that rely on the less resource demanding hash functions and XOR computations are discussed and suggested for security in IoT systems. Security concerns for RFID technology and other IoT networks are reviewed, and privacy-preserving, security protection frameworks that are scalable and consume little energy are proposed.},
