Jiangshan Yu (于江山)

I'm Associate Director (Research) at Monash Blockchain Technology Centre, a member of the Monash Cybersecurity Lab, and a Lecturer (~US Assistant Professor) in the Faculty of Information Technology at Monash University. I received my PhD in Computer Science from the University of Birmingham (UK), supervised by Prof. Mark Ryan (HP Inc. Chair in Cybersecurity). I did my postdoc with Prof. Paulo Esteves-Verissimo (IEEE and ACM Fellow) at SnT, University of Luxembourg.

My research interests are in the area of cybersecurity. In particular, the focus of my research has been on (designing and attacking) blockchain systems, user privacy, cryptographic key management, and ledger-based applications.

IMPACT





Selected research projects:

Our research on blockchain consensus, called RepuCoin, provides the first blockchain system that is able to tolerate 51% attacks. This system may save potentially millions of US dollars every month from the attacks, and increase the confidence of enterprise in adapting blockchains. (For example, from April 2018 to Feb 2019, at least ten successful 51% attacks are identified, with a total loss of over 28 million US dollars.) This work has been reported by over 60 news media globally including Monash News, Finder, 今日头条(Toutiao), ZDNet, Sohu, BTC Wires, ScienceDaily, Ethereum World News, EurekAlert!, The US Breaking news, Homeland Security Today, etc.

Our work on the ledger-based end-to-end secure messaging system, called DECIM, provides the first end-to-end secure messaging system that is able to detect the compromise of secret keys. This system has been further developed by a University of Birmingham spin-off as open source software, and have attracted funding support from Innovate UK. The system has attracted news media's attention as a breakthrough in messaging privacy, and has been featured in more than 40 international and national news media including Science Daily, Phys.org, ACM TechNews, EurekAlert, Futurism, and Silicon Republic. The news has been released in more than 7 languages by media from more than 10 countries including UK, US, Germany, Ireland, Luxembourg, Turkey, Spain, and India. I have also been invited for an interview (to explain my innovation to general listeners) by Eldoradio --- a member of RTL group which is one of the world's leading producers of television content and the leading European entertainment network.

For blockchain system analysis, we identified vulnerabilities on the NEO blockchain ( FC'20') and CryptoNote-style blockchains (FC'20, CSF'19 , FC'19 , and AsiaCCS'19). For the NEO blockchain, we identified design flaws to break the consensus liveness and safety, which allows an attacker to spend the same coin multiple times. For CryptoNote-style blockchains, we traced 70%-91% transactions of supposed-to-be privacy-preserving cryptocurrencies, including Monero, ByteCoin, and DigitalNote. We also provided optimal solutions within our formal model. Here are some news articles (News 1, News 2) reporting our works.

In 2019, there are over 250 decentralised exchanges with a total trading volume of over AU$3 billion. Most of them are based on the atomic swap protocol on Ethereum to enable cross-ledger communications. Our work (AFT'19') has identified an overlooked design flaw of the protocol. The flaw allows a trader to cheat others to gain extra profit. Our proposed fixes are included in the Ethereum Improvement Proposals (EIP-2266). Here is a news article covering this work.

I've co-designed a secure booting solution for Huawei Ltd, the largest telecommunications equipment manufacturer in the world, to manage their next generation network devices securely.
