Trust Evaluation Model in IoT Environment: A Comprehensive Survey

The Internet of Things (IoT) is a rapidly evolving field that provides seamless connections to physical object, making it part smart environment. To fully realize the potential power between these objects in IoT, trust them critical. Conventional security measures are not sufficient provide comprehensive for this world. Trust used reduce risk insecurity when nodes connected Internet. In an IoT environment, various models have been proposed Wireless Sensor Networks (WSNs) and Radio Frequency Identification (RFID). Nevertheless, adapted dynamic uncertain environment intelligent IoT. Therefore, article reviews characteristics recent works models. A study has conducted on classification set factors discussed, such as characteristics, architecture, distribution, aggregation technique, model type, attack type. addition, paper readers with understanding current existing directs future propose new satisfy all should be considered developing model. Finally, some research challenges directions identified.
