Indistinguishability obfuscator
Web16 dec. 2024 · Abstract. A program obfuscator takes a program and outputs a “scrambled” version of it, where the goal is that the obfuscated program will not reveal much about its structure beyond what is apparent from executing it. There are several ways of formalizing this goal. Specifically, in indistinguishability obfuscation, first defined by Barak et al. … Web28 okt. 2015 · Publication Date. “Indistinguishability obfuscation” is a powerful concept that would yield provably secure versions of every cryptographic system we’ve ever developed and all those we’ve been unable to develop. But nobody knows how to put it into practice. Last week, at the IEEE Symposium on Foundations of Computer Science, MIT ...
