Cross ecological interconnection and security

With the evolution of IoT technology, the problem of IoT fragmentation has gradually become prominent: diverse IoT connection protocols, numerous platforms, and strong hardware and chip heterogeneity. The high ecological barriers between devices and products from different manufacturers make it difficult to connect and exchange, which limits the further development of the Internet of Things. The decentralized nature of blockchain is a good means to reconcile the interests of different entities in the Internet of Things and achieve cross ecological interconnection of the Internet of Things. The Smart Home Cross Ecological Interconnection Protocol Matter is achieved through blockchain to enable trusted access to cross ecological devices. However, existing work still faces issues such as low interoperability performance, insufficient full lifecycle security protection, lack of reliable IoT data storage, and high risks of data privacy leakage from end devices. There is still a distance to achieve secure and efficient IoT cross ecological interconnection.

This project will study the cross ecological interconnection and security guarantee mechanism of the Internet of Things based on blockchain, including cross ecological data security sharing technology, trusted differential technology for IoT applications, and trusted digital identity construction technology based on new RF fingerprints.
