Cryptography and Information Security (CIS) Seminar

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.

Gregory Meyer: Classical Verification of Quantum Computational Advantage
Friday, October 8, 2021 - 1:00pm to 2:30pm


Ilan Komargodski: A Logarithmic Lower Bound for Oblivious RAM (for all parameters)
Friday, September 17, 2021 - 1:00pm to 2:30pm
Hemanta Maji: Computational Hardness of Optimal Fair Computation
Friday, September 10, 2021 - 1:00pm to 2:30pm
Abstract: Characterizing the limits of achievable security using the 
most conservative hardness of computation assumptions is one of the 
fundamental principles of cryptographic research. For instance, 
Geoffroy Couteau: Title: Correlated Pseudorandom Functions from Variable-Density LPN
Friday, May 28, 2021 - 3:30pm

Abstract: Correlated secret randomness is a useful resource for many cryptographic applications.

Henry Corrigan-Gibbs: Lightweight Techniques for Private Heavy Hitters
Friday, May 14, 2021 - 1:00pm to 2:30pm

ABSTRACT:  This talk will present a new protocol for solving the private heavy-hitters problem. In this problem, there are many clients and a small set of data-collection servers. Each client holds a private bitstring.
