Christopher Patton

I'm a cryptography engineer at Cloudflare Research focused on the last mile of cryptography research. My work ranges from security analysis and protocol design to implementation and deployment. I've spent most of my time at the intersection of privacy and standardization: I'm leading a significant amount of work in the PPM working group at IETF, which aims to bring MPC and other tools to bear on user measurement; and I contributed to the design of the Encrypted Client Hello extension for TLS. I've also spent some time helping with Cloudflare's post-quantum transition.

I finished my PhD in 2020 under Tom Shrimpton at the University of Florida. My thesis focused on bridging the gap between the proven security of cryptographic protocols and their security in the real world. I began my crypto education with Phil Rogaway at the University of California, Davis, where I earned my master's and bachelor's. I interned on the Crypto team at Cloudflare (SF) during the summer of 2018. I've done two internships at Google, the first on the Cloud Security team (KIR, 2015) and the second on the Chrome Protector team (MON, 2016).
