WebOct 28, 2015 · The ideal obfuscation scheme would take the source code for a program and rewrite it so that it still yields a working program, but it is impossible to determine what operations it was executing. Theorists quickly proved that ideal obfuscation would enable almost any cryptographic scheme that they could dream up. WebIn fact, almost any cryptographic primitive you can think of can be fairly directly derived from obfuscation, starting from basic primitives such as public key encryption and digital signatures to fancier notions such as multiparty secure computation, fully homomorphic encryption, zero knowledge proofs, and their many variants.
