This Friday at 10:30 we have our own Yilei Chen talking about his 
Eurocrypt 2017 paper. Lunch to follow.

Hariri Institute for Computing Seminar room MCS 180, 111 Cummington Mall

Cryptanalyses of candidate branching program obfuscators


Cryptographic multilinear maps (graded encodings) and program 
obfuscation are fascinating tools. Their births opened a new way of 
thinking in cryptography. However, very little is known about the 
concrete security of these new candidate constructions. In this talk I 
will describe the candidate branching-program obfuscator proposed by 
Garg, Gentry, Halevi, Raykova, Sahai and Waters (GGHRSW, FOCS 2013), and 
show how we break it in certain settings.

Based on joint work with Craig Gentry and Shai Halevi.
