A Multi-level Trusted Clustering Mechanism for IOT

To solve the problem of data transmission security in the perception layer network, we propose a multi-level trusted clustering mechanism. This mechanism combines multi-level clustering, identity authentication and trusted computing, we also propose a two-way transmission authentication method based on symmetric cryptography. Finally, platform integrity is authenticated. The authentication scheme improves the security of intra-cluster communication and enables the network to form a secured and trusted cluster structure.
