Rio LaVigne: Adversarially Robust PropertyPreserving Hash Functions Friday, February 22, 2019  10:30am to 12:00pm 

Alex Lombardi: NonInteractive Zero Knowledge and Correlation Intractability from CircularSecure FHE Friday, February 15, 2019  10:30am to 12:00pm Abstract: We construct noninteractive zeroknowledge (NIZK) arguments for NP from any circularsecure fully homomorphic encryption (FHE) scheme. In particular, we obtain such NIZKs under a circularsecure variant of the learning with errors (LWE) problem.

Oxana Poburinnaya: Fully bideniable interactive encryption Friday, November 9, 2018  10:30am to 12:00pm Abstract: Deniable encryption guarantees an extremely strong level of privacy: It provides the parties with algorithmic ways to come up with fake keys and random inputs that 

Mark Zhandry: Quantum Lightning Never Strikes the Same State Twice Friday, November 2, 2018  10:30am to 12:00pm Abstract: Quantum nocloning states that it is physically impossible to clone a quantum state. Nocloning is a central to the study of quantum cryptography, where it allows for objects such as physically unforgeable currency.
