ICC Cybersecurity Colloquium Is Sept. 18

Bo Chen, Computer Science

The Institute of Computing and Cybersystems’s (ICC) Center for Cybersecurity (CyberS) will present a Cybersecurity Colloquium on Monday, September 18, 2023, from 12-1 pm in EERC 226. Ronghua Xu, Applied Computing, will present his talk, “A Secure by Design Federated Microchain Fabric for Internet-of-Things (IoT) System.”

Organized by Associate Professor Bo Chen, Computer Science, with coordinators Xinyu Lei (Computer Science) and Kaichen Yang (Electrical and Computer Engineering), the Colloquium series of talks aims to provide a university-wide platform for cybersecurity faculty and students to communicate more robustly. 

The colloquiums will feature talks from faculty members, students, and invited speakers, encouraging discussions about cybersecurity among faculty and students. Food and beverages will be served. Come and enjoy the cybersecurity happy hour!

Details about the first Cybersecurity Colloquium are below.

  • Date: Monday, September 18
  • Time: 12-1 pm
  • Location: EERC 226
  • Presenter: Ronghua Xu, Applied Computing
  • Talk Title: A Secure by Design Federated Microchain Fabric for Internet-of-Things (IoT) System

Abstract: The fast integration of 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 to 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 the sixth-generation (6G) communication networks to provide decentralized, secure, scalable, resilient, and efficient network services and dynamic resource management for complex and heterogeneous IoT ecosystems, like 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 specificaly 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, 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 the light on future opportunities that guarantee scalability, dynamicity, and security for multi-domain IoT ecosystems atop NGNs. Moreover, I will talk on applying the key ideas of microchain into different IoT scenarios, like IoT network security, data marketplaces, and urban air mobility systems. Finally, I will conclude my talk by presenting A vision of NGNs that provide ubiquitous and pervasively network access for users.
