Design of Data Communication Scheme for Privacy Protection in Smart IoT Environment

The Internet of Things is a wide-ranging concept that applies not only to objects but also in our everyday life. Home networks utilizing smart devices, automobile technology, and treatment at medical institutions are typical examples of implementations of the Internet of Things in everyday life. However, there are issues about fragile security that stand in stark contrast to the rapid popularization of the Internet of Things. There was a case of a hacked chip in a user device that spread malignant code and spam mail followed by a data leak. Besides, Internet of Things devices like the ones used as domestic smart home devices are found to be more prone to be the target of distributed denial of service attacks. Therefore, in this paper, we present a plan for the registration of a device, the formation of a session key, and user authentication to ensure secure communication. Additionally, we present a plan for a message communication protocol. The communication scheme proposed here is also analyzed for data stability and encryption efficiency.
