Blockchain Technologies

Blockchain technology has attracted increasing attention from both academia and industry. Its popular applications include cryptocurrency, smart contracts, non-fungible tokens (NFT), Web3 and many others. It is an interdisciplinary field encompassing distributed systems, security, privacy, cryptography, database and compiler. We conduct fundamental and applied research in blockchain consensus and decentralized applications. Our projects are funded by federal agencies, such as FHWA and the results of our research are published in top venues, such as IEEE Transactions on Parallel and Distributed Systems and IEEE ICDCS.

Decentralized Vehicle Credential Management System Based on Consortium Blockchain

To realize the full potential of connected and automated vehicles to transform the US transportation system, it is important to ensure the vehicle communication is secure and privacy-preserving. In this situation, a digital certificate is critical to provide communication integrity, authenticity and privacy. Existing solutions based on centralized security credential management systems are inherently vulnerable to emerging cyber-security risk and singlepoint failure. To address the weakness of centralized systems being adopted, this project seeks to utilize the recent breakthrough of blockchain technology, in particular the consortium blockchain, to design and implement an innovative decentralized vehicle credential management system. The proposed decentralized credential management system based on consortium blockchain can not only greatly improve the robustness and security of the credential management system for vehicles and thus realizes high-security assurance for authentic V2V and V2I communication, but also incorporate state-of-theart achievements in cryptography to ensure strong anonymity to prevent hackers from tracing the locations of vehicles and ensuring vehicle privacy.

A Blockchain-Based Decentralized IIoT Management System

Blockchain has been increasingly used to secure data collection, storage and transfer in various Industrial Internet of Things (IIoT) environments. We design a blockchain-based decentralized IIoT management system for censorship resistance, which employs a diffusion mechanism to deliver messages from sensors to full nodes, an augmented consensus protocol to check data losses and facilitate opportunistic outcome delivery and a public key-based aggregation method to reduce communication complexity and signature verification.
