Cryptography and Information Security (CIS) Seminar

Rio LaVigne: Adversarially Robust Property-Preserving Hash Functions
Friday, February 22, 2019 - 10:30am to 12:00pm
Alex Lombardi: Non-Interactive Zero Knowledge and Correlation Intractability from Circular-Secure FHE
Friday, February 15, 2019 - 10:30am to 12:00pm
Abstract: We construct non-interactive zero-knowledge (NIZK) arguments for NP from any circular-secure fully homomorphic encryption (FHE) scheme. In particular, we obtain such NIZKs under a circular-secure variant of the learning with errors (LWE) problem.
Nadia Heninger: Lattice Attacks against Weak ECDSA Signatures in Cryptocurrencies
Friday, May 31, 2019 - 10:30am to 12:00pm

Abstract

Elette Boyle: Compression Vector OLE and More
Tuesday, January 15, 2019 - 10:30am to 12:00pm
Abstract:
We will speak about a CCS'18 result and the bigger picture of a new line of work in compressing different types of pseudorandom correlations.
 
Amit Sahai: Obfuscation without multilinear maps
Friday, November 30, 2018 - 10:30am to 12:00pm
Abstract:
 
Hoeteck Wee: Obfuscation from LWE: How Far Are We?
Friday, November 16, 2018 - 10:30am to 12:00pm

Abstract:
GGH15 provide a way to encode many pairs of matrices, such that we can
check whether any subset product is zero, while potentially hiding all
other information about the matrices. This immediately yields a

Oxana Poburinnaya: Fully bi-deniable 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 no-cloning states that it is physically impossible to clone a quantum state.  No-cloning is a central to the study of quantum cryptography, where it allows for objects such as physically unforgeable currency.
Yevgeniy Dodis: Small-Box Cryptography
Friday, October 19, 2018 - 10:30am to 12:00pm

Abstract: 

Willy Quach: Laconic Function Evaluation and Applications
Friday, October 5, 2018 - 10:30am to 12:00pm

Abstract:  We introduce a new cryptographic primitive called laconic function
