Leo de Castro: Functional Commitments for All Functions, under Transparent Setup and Standard Lattice Assumptions
Friday, February 17, 2023 - 10:30am to 12:00pm

Abstract: A functional commitment scheme enables a user to concisely commit to a function from a specified family, then later concisely and verifiab

Lakyah Tyner: Nearly Optimal Property Preserving Hashing
Friday, February 10, 2023 - 10:30am to 12:00pm

Abstract: Property-preserving hashing (PPH) consists of a family of compressing hash functions h such that, for any two inputs x, y, we can correctly identify whether some property P(x, y) holds given only the digests h(x), h(y).

Anne Broadbent: Bob's sidekick(or how limitations on tripartite quantum correlations are useful for cryptography)
Friday, March 4, 2022 - 10:30am to 12:00pm


Anne Broadbent: Bob’s sidekick (or how tripartite quantum correlations are weaker than you thought and how this is useful for cryptography)
Friday, December 10, 2021 - 1:00pm


Merav Parter: A Graph Theoretic Approach for Resilient Distributed Algorithms
Monday, December 6, 2021 - 4:00pm to 5:00pm
Lior Rotem: Tighter Security for Schnorr Identification and Signatures: A High-Moment Forking Lemma for Sigma- Protocols
Friday, November 5, 2021 - 1:00pm to 2:30pm


Qipeng Liu: Hidden Cosets and Applications to Unclonable Cryptography
Friday, October 29, 2021 - 1:00pm to 2:30pm
Katerina Sotiraki: Sumcheck Arguments and their Applications
Friday, October 22, 2021 - 1:00pm to 2:30pm

Abstract: In this talk, I will present sumcheck arguments; a new class
of interactive protocols which show that "split-and-fold protocols"
(such as Bulletproofs and many more) are consequences of the Lund et
al. sumcheck protocol from 1992.
