Jiangshan Yu

I'm a lecturer (equivalent to U.S. assistant professor) at Monash University, Australia, and an honorary research fellow working with Prof. Mark Ryan (HP Chair in Cybersecurity ) in the School of Computer Science, University of Birmingham, UK, where I received my PhD in computer science. 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 and cryptography. In particular, the focus of my research has been on design and analysis of cryptographic protocols, cryptographic key management, blockchain consensus, and ledger-based applications.

Main research impact:

My research on blockchain consensus, called RepuCoin, provides the first blockchain system that is able to tolerate the 51% attack. 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.

I've also 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.
