multiplication! In 2009 Gentry completed the picture with a partially homomorphic system, based on lattices, where you could do a number of additions and multiplications before losing "precision". How is this compatible with Barak result, you ask? The black box proof of  is in the multilinear model, which means it is under the assumption that the attacker can only do a limited set of (algebraic) operations. If two programs are semantically equivalent then traditional deobfuscation techniques like symbolic execution, constant propagation + folding, dead code removal, etc. should take you pretty far. I plan to read the other links provided when I have time, but feel free to help me out by explaining how wrong I am, if that the case.
The papers are over my head, but they both at least mention homomorphic encryption. We had RSA, which is multiplicatively homomorphic (this property is Air Max 90 Atmos Tiger Camo the reason behind the need for good padding!). We also had Paillier, which is additively homomorphic. We even had Boneh Goh Nissim, where you could do any number of additions plus one Nike Air Max 90 Top Quality

If you interested in crypto, you should probably set a bookmark on and read all his comments. Especially if you find me annoying, because I have a habit of setting him up for great comments by being wrong about things.

is very much not practical by any standard, and doesn look anything like the usual software obfuscation used today, even white box. This thing requires at the very least that multilinear maps and fully homomorphic encryption are anywhere near practical, which is not the case today (and may Nike Air Max 90 Running Shoes
