My hearty congratulations to MacArthur Fellowship for handing down the right decision and naming Craig Gentry its fellow, better known as a genius. What a truly deserving winner! As the readers of this blog know full well, Craig has done seminal work in cryptography – time and time again. In his prize-winning Ph.D. work in 2009 Craig achieved what many had considered to be impossible – fully-homomorphic encryption. In short three years he (with co-authors, Sanjam Garg and Shai Halevi) proposed another object – a cryptographic multilinear map whose existence I’d been willing to bet against. Last year Craig (with several more co-authors) constructed an obfuscation mechanism with two amazing properties: it looks impossibly difficult to achieve and useless for any cryptographic applications. Both statements – you see the pattern here – are wrong. Indistinguishability obfuscation, as it has become known, quite plausibly exists and we are still in the process of grasping its true potential.
