Henry Corrigan GibbsAssistant Professor

research
I build systems that use cryptography to empower and protect their users. The projects that excite me the most: (1) serve the interests of the end user, (2) provide strong and precise forms of security, often using new cryptographic ideas, and (3) have impact through real-world deployment.

My recent projects include:
Techniques for reducing the computational cost of private information retrieval in theory and in practice
SafetyPin and True2F, systems that provide strong hardware-backed security protections, while still protecting against a wide class of hardware faults and backdoors
Prio, a system for the privacy-preserving collection of aggregate statistics (adopted by Mozilla's Firefox browser, offered as a service by ISRG, the entity behind Let's Encrypt, and used in Android and iOS to measure the effectiveness of their Exposure Notification systems)
The study of preprocessing attacks on cryptographic primitives and the risks they pose to our standardized primitives, such as the AES block cipher and the NIST family of elliptic curves
