Trustworthy gateway system providing IoT trust domain of smart home

Present IoT trust method for smart home installs security technologies and security equipment directly into each thing. But this method is practically difficult to install security technologies and security equipment on the things with limited processing power. Thus, the trust method for IoT is necessary to support the trust domain for things that constitute the IoT rather than installing security technology and security equipment for each thing. Therefore, this paper proposes a trustworthy gateway system architecture that constructs an IoT trust domain which can protect the IoT safely from the malicious attack.
