Cross-Domain Trust Remote Attestation Scheme in the Internet of Things

The Internet of Things realizes the interconnection of every thing. With the development of the Internet of Things, the scale of the Internet of Things is getting larger and larger, and there are often multiple Internet of Things node domains. They have different security policies and cooperate with each other to realize complex functions. Because of the indirectness and uncertainty of cross-domain interaction, multi-domain Internet of Things faces more security risks. Therefore, we propose a cross-domain trust remote attestation scheme in the Internet of Things. First, we evaluate the direct interactive trust of terminal nodes, then refer to the recommended trust of multiple domains. On this basis, a cross-domain trust relationship construction mechanism is established to realize remote attestation of node security. Simulation experiments verify the effectiveness of the scheme. And it can better identify cross-domain malicious interactions.
