An improved trust-based security framework for internet of things

The Internet plays a vital role in the massive growth of the emerging Internet of Things (IoT). IoT helps all electronic devices to communicate with other devices and with the human with the help of the Internet. IoT enables the devices to sense environmental changes or mission-critical data. These critical data that are sensed by the IoT devices are forwarded to the public cloud storage with the help of Gateway nodes. Later these sensed data are utilized for decision making. However, high-risk insecurity is a major concern in IoT sensed data. In this paper, a trust-based security method with Direct and Indirect trust evaluation technique has been implemented to provide highly secure data transmission in the network. The simulation result has proven that trust-based security can improve data confidentiality when compared with available protocols.
