Cryptography and Information Security (CIS) Seminar

Valerio Pastro: Essentially Optimal Robust Secret Sharing with Maximal Corruptions
Friday, April 29, 2016 - 10:30am to 12:00pm


Prabhanjan Ananth: Universal Obfuscation and Witness Encryption: Boosting Correctness and Combining Security
Friday, April 22, 2016 - 10:30am to 12:00pm
Abstract:  Over the last few years a new breed of cryptographic primitives has arisen: on one hand they have previously unimagined utility and on the other hand they are not based on simple to state and tried out assumptions.
Prashant Vasudevan: Fine-Grained Cryptography
Friday, April 8, 2016 - 10:30am to 12:00pm
Title: Annihilation Attacks for Multilinear Maps: Cryptanalysis of Indistinguishability Obfuscation over GGH13
Friday, April 1, 2016 - 10:30am to 12:00pm
Abstract: In this work, we put forward a new class of polynomial-time attacks on the original multilinear maps of Garg, Gentry, and Halevi (2013).
Adam Sealfon: Network Oblivious Transfer
Friday, March 11, 2016 - 10:30am to 12:00pm
Abstract: Motivated by the goal of improving the concrete efficiency of secure multiparty computation (MPC), we study the possibility of implementing an infrastructure for MPC.
Aloni Cohen: GGM is a Weakly One-Way Family of Functions
Friday, February 19, 2016 - 10:30am to 12:00pm
Abstract: We prove that the for any constant $\epsilon>0$, GGM pseudo-random function
family is a $1/n^{2+\epsilon}$-weakly one-way family of fun
Elette Boyle: New Developments in Function Secret Sharing
Friday, February 12, 2016 - 10:30am to 12:00pm
Daniel Genkin: Efficient Multi-Party Computation: from Passive to Active Security using Additive-Attack Resilient Circuits
Friday, February 5, 2016 - 10:30am to 12:00pm
Sanjam Garg: Avoiding Sub-Exponential Loss in Obfustopia
Friday, December 11, 2015 - 10:30am to 12:00pm

Abstract: Various applications of indistinguishability obfuscation suffer from an exponential loss in the security reduction. In this talk, I will describe how this loss can be circumvented in various contexts.

Power Wars: Surveillance, Drones, and Obama's Post - 9/11 Presidency
Friday, December 4, 2015 - 4:00pm to 5:30pm
