Abstract: 
Charanjit Jutla: Upending Stock Market Structure Using Secure Computation
Friday, November 20, 2015 - 10:30am to 12:00pm

Abstract:

The stock markets have two primary functions, that of providing liquidity and price discovery. While the market micro-structure

Fabrice Ben Hamouda: New Techniques for SPHFs and Efficient One-Round PAKE Protocols
Friday, November 13, 2015 - 10:30am to 12:00pm

Abstract:  Password-authenticated key exchange (PAKE) protocols allow two players to agree on a shared high entropy secret key, that depends on their own passwords only.

Jean-Jacques Quisquater: Is the Group Theory Fully Used for Cryptography
Friday, March 18, 2016 - 10:30am to 12:00pm

Abstract:  In "Rubik's for Cryptographers" Christophe Petit and Jean-Jacques Quisquater
(Notices of AMS, June/July  2013, Volume 60, Issue 06, pp. 733-739) gave 3 examples
of parallel research about cryptographic Cayley hash functions and Babai's conjecture on the

Anne Broadbent: Quantam Homomorphic Encryption for Circuits of Low T-Gate Complexity
Friday, October 30, 2015 - 10:30am to 12:00pm

Abstract:  Fully homomorphic encryption is an encryption method with the property that any computation on the plaintext can be performed by a party having access to the ciphertext only.

Sidharth Telang: Output-Compressing Randomized Encodings and Applications
Friday, October 9, 2015 - 10:30am to 12:00pm
Abstract: We consider randomized encodings (RE) that enable encoding a Turing machine P and input x into its “randomized encoding” \hat{P(x)} in sublinear, or even polylogarithmic, time in the running-time of P(x), independent of its output length.
Noah Stephens-Davidowitz: Solving SVP (and CVP) in 2^n Time via Discrete Gaussian Sampling
Friday, September 25, 2015 - 10:30am to 12:00pm
Abstract: We show a $2^{n+o(n)}$-time algorithm for the Shortest Vector Problem on n-dimensional lattices (improving on the previous best-known a
Silas Richelson: On the Hardness of Learning with Rounding with Small Modulus
Friday, September 18, 2015 - 10:30am to 12:00pm

Abstract: We show the following reductions from the learning with errors problem (LWE) to the learning with rounding problem (LWR): (1) Learning the se

Ranjit Kumaresan: Secure Computation with Minimal Interaction, Revisited
Friday, September 11, 2015 - 10:30am to 12:00pm

Abstract: Motivated by the goal of improving the concrete efficiency of secure multiparty computation (MPC), we revisit the question of MPC with only two rounds of interaction.
