About the Event

Cryptography is a key component of the security of the Internet. Unfortunately, the process of using cryptography to secure the Internet is fraught with failure. Cryptography is often fragile, and a single mistake can have devastating consequences on security. This fragility is further complicated by the distributed and diverse nature of the Internet, where rapid and wholesale changes are impossible to deploy. As a result, the cryptography used to secure the Internet is a vast array of algorithms, protocols, implementations and parameters that reflects the diverse nature of the Internet.

This dissertation shows how to use empirical methods from large-scale network measurement to study how cryptography is deployed on the Internet, and shows this methodology can gain insights into fragile cryptographic ecosystems that are not possible without an empirical approach.
