Title: Candidate Indistinguishability Obfuscation for all circuits and
its Applications

Sanjam Garg. IBM.

Abstract: Indistinguishability obfuscation requires that given any two
equivalent circuits C_0 and C_1 of similar size, the obfuscations of C_0
and C_1 should be computationally indistinguishable. In this talk I will
give a construction for indistinguishability obfuscation that supports
all polynomial-size circuits and talk about its applications:

- I will describe a candidate construction for indistinguishability
obfuscation for NC1 circuits based on multilinear maps.

- I will show how to use indistinguishability obfuscation for NC1
together with Fully Homomorphic Encryption (with decryption in NC1) to
achieve indistinguishability obfuscation for all circuits.

- Finally, I will show how indistinguishability obfuscation for circuits
can be used to realize many applications such as functional encryption
and witness encryption.
