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). |

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. |
