Security Challenges in Computing System, Communication Technology and Protocols in IoT system

With the help of cyber-physical system, sensors, actuators, wireless sensor network, personal area network, wireless communication of near field communication, RFID and conventional internet, it is possible to impart intelligence to devices and make them smarter. IoT (Internet of Things) inter-connects numerous devices from anywhere at any time. All the industries are moving towards adopting IoT due to its ability to automate the operations that enable remote monitoring. The major challenges implementing IoT are interoperability, computation, standardization, privacy, and security. This paper analyses security challenges in the existing protocol, communication technology, and computation techniques.
