# Cryptography and Information Security (CIS) Seminar

 Valerio Pastro: Essentially Optimal Robust Secret Sharing with Maximal CorruptionsFriday, April 29, 2016 - 10:30am to 12:00pmAbstract: Prabhanjan Ananth: Universal Obfuscation and Witness Encryption: Boosting Correctness and Combining SecurityFriday, April 22, 2016 - 10:30am to 12:00pmAbstract:  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 CryptographyFriday, April 8, 2016 - 10:30am to 12:00pm Abstract: Title: Annihilation Attacks for Multilinear Maps: Cryptanalysis of Indistinguishability Obfuscation over GGH13Friday, April 1, 2016 - 10:30am to 12:00pmAbstract: 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 TransferFriday, March 11, 2016 - 10:30am to 12:00pmAbstract: 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 FunctionsFriday, February 19, 2016 - 10:30am to 12:00pmAbstract: We prove that the for any constant $\epsilon>0$, GGM pseudo-random functionfamily is a $1/n^{2+\epsilon}$-weakly one-way family of fun Elette Boyle: New Developments in Function Secret SharingFriday, February 12, 2016 - 10:30am to 12:00pm Abstract: Daniel Genkin: Efficient Multi-Party Computation: from Passive to Active Security using Additive-Attack Resilient CircuitsFriday, February 5, 2016 - 10:30am to 12:00pmAbstract: Sanjam Garg: Avoiding Sub-Exponential Loss in ObfustopiaFriday, December 11, 2015 - 10:30am to 12:00pmAbstract: 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 PresidencyFriday, December 4, 2015 - 4:00pm to 5:30pmPOWER WARS: SURVEILLANCE, DRONES, AND OBAMA’S POST-9/11 PRESIDENCY Charlie Savage, Pulitzer Prize winning, New York Times journalist,
