Talk Title: Secure-By-Design Federated Microchain Fabric for Internet-Of-Things (Iot) System
Talk Abstract: The fast integration of the fifth-generation (5G) communication, Artificial Intelligence (AI), and the Internet of Things (IoT) technologies is envisioned to enable Next Generation Networks (NGNs) that provide diverse intelligent services for Smart Cities. However, the ubiquitous proliferation of highly connected end devices and user-defined applications bring serious services provisioning, security, privacy, and management challenges on the centralized framework adopted by conventional networking systems. My research aims for a large-dimensional, autonomous and intelligent network infrastructure that integrates Machine Learning (ML), Blockchain, and Network Slicing (NS) atop sixth-generation (6G) communication networks to provide decentralized, secure, scalable, resilient, and efficient network services, and a dynamic resource management for complex and heterogeneous IoT ecosystems, such as Metaverse, smart transportation, and Unmanned Aerial Vehicle (UAV) systems, etc. Therefore, this presentation will introduce “a Secure-by-Design Federated Microchain Fabric for Internet-of-Things (IoT) System, which lays down a solid foundation for constructing the secure and decentralized networking infrastructure under multi-domain IoT scenarios. From the system architecture aspect, I will specially focus on microDFL, which is a novel hierarchical IoT network fabric for decentralized federated learning (DFL) atop the federation of lightweight Microchains. Under the framework of federated Microchain, I will explain two lightweight microchains for IoT systems, called Econledger and Fairledger, which adopt efficient consensus protocols to improve performance at the network of edge. Following that, a novel epoch randomness-enabled consensus committee configuration scheme called ECOM has been designed to enhance scalability and security of the small scale microchain, and a smart contract enabled inter-ledger protocol has been implemented to improve interoperation during cross-chain operations. After that, I will explain a novel concept of a dynamic edge resource federation framework by joint combination of a federated microchain fabric with network slicing technology, which sheds light on future opportunities that guarantee scalability, dynamicity, and security for multi-domain IoT ecosystems atop NGNs. Moreover, I will also talk on applying the key ideas of microchain into different IoT scenarios, such as IoT network security, data marketplaces, and urban air mobility systems. Finally, I will conclude my talk by presenting a vision towards NGNs that provide ubiquitous and pervasively network access for users.
