Center member Tijay Chung is working to better understand and improve the current PKI ecosystem in the Internet
A public key infrastructure (PKI) helps provide secure communications over an untrusted network. Because of this, PKIs are central to security on the Internet, and there are a number of large-scale PKIs in use today such as DNSSEC, HTTPS, and RPKI. Taejoong (Tijay) Chung, an Assistant Professor of Computer Science, is measuring the PKI ecosystem and exploring ways to improve its security in practice. Tijay’s DNSSEC research was recognized with a Distinguished Paper Award at USENIX Security 2017 and the 2019 Applied Networking Research Prize by the Internet Research Task Force (IRTF) and the Internet Society. In addition, his recent RPKI research is funded by a new grant from the National Science Foundation.
