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.

互联网在新兴的物联网（IoT）的大规模增长中起着至关重要的作用。物联网通过互联网帮助所有电子设备与其他设备以及与人类进行通信。物联网使设备能够感知环境变化或关键任务数据。物联网设备感测到的这些关键数据将在网关节点的帮助下转发到公共云存储。之后，将这些感测到的数据用于决策。但是，高风险的不安全性是物联网感知数据中的主要问题。在本文中，已经实现了一种具有直接和间接信任评估技术的基于信任的安全方法，以在网络中提供高度安全的数据传输。仿真结果证明，与可用协议相比，基于信任的安全性可以提高数据机密性。
