Security in Internet of Things (IoT): Challenges and Models
The Internet of Things (IoT) has grabbed the attention of the scientific community in recent years. IoT is a recently formed technology that will be the future of the web, allowing distinct everyday objects to communicate with each other without any human interaction. It is one of the most hotly debated fields in both academia and industry for current and future study areas. IoT security and privacy issues have proven to be critical objectives. This paper includes IoT models, schemes, and implementation issues related to different IoT technologies and devices. It focuses on security challenges of IoT communications such as privacy, authentication, integrity of data, and service availability, mostly in hardware aspects. Attacks and modern vulnerabilities, as well as countermeasures, are taken into account. Various IoT security models are described along with security challenges.
