Their paper, titled “Conifer: Centrally-managed PKI with blockchain-rooted trust,” describes a new blockchain-based public key infrastructure that allows users to communicate securely over intrinsically insecure networks such as the Internet. Their research was presented at Blockchain-2018, a conference held in Halifax, Nova Scotia from July 30 to August 3, 2018.

“Congratulations to Yuhao, Woojung and Raouf for receiving the prestigious best student paper award at Blockchain-2018,” said Dan Brown, Director of the David R. Cheriton School of Computer Science. 

“Their paper describes a novel public key infrastructure — which they call Conifer — that has both centralized control and blockchain-backed trust. Their experimental results show that Conifer performs significantly better than other blockchain-based systems, with faster lookup and dramatically reduced storage overhead. Scalability is so important for blockchain-based systems, and they show that relative to traditional centralized public key infrastructures, their new system scales easily with negligible performance penalty.”
