A New Design for Cryptography’s Black Box
> https://www.quantamagazine.org/20150902-indistinguishability-obfuscation-cryptographys-black-box/

> A two-year-old cryptographic breakthrough has proven difficult to put
> into practice. But new advances show how near-perfect computer
> security might be surprisingly close at hand.


> Indistinguishability obfuscation begins by positing two programs that
> compute the exact same outputs by different methods — for example,
> the equivalent functions f(x) = x(a + b) and f(x) = ax + bx. For any
> set of three inputs — a, b and x — each program produces the same
> result as the other, but arrives at that result by a different path.
> IO says that given two equivalent programs, it should be possible to
> encrypt them so that users cannot tell which version they have, no
> matter how much they poke around.
