A trusted IoT architecture model

The internet of things (IoT) has been widely concerned and developed in the world,and its security has been paid more and more attention.However,due to the characteristics of the IoT itself,a lot of security measures in the internet field can’t be applied directly.The current security strategy mainly provide solutions according to the threat of the IoT one by one.In face of increasingly intelligent,systematic,integrated security threats,a trusted IoT architecture of two layers and tri-elements,which brought about a whole trusted security mechanism according to the function of IoT.Starting with the integrity and safety inspection of hardware and software of sensor devices,the trusted chain was transmitted until the application layer,and data was processed according to behavior trusted value in application layer.At the same time,the control function and the data function were separated,and the security strategies cooperated and verified with each other,therefore improving the ability of the IoT to deal with security threats effectively.
