### Paper: Zero-Knowledge twenty years after its invention

Authors: Oded Goldreich URL: http://eprint.iacr.org/2002/186 Search ePrint Search Google Zero-knowledge proofs are proofs that are both convincing and yet yield nothing beyond the validity of the assertion being proven. Since their introduction about twenty years ago, zero-knowledge proofs have attracted a lot of attention and have, in turn, contributed to the development of other areas of cryptography and complexity theory. We survey the main definitions and results regarding zero-knowledge proofs. Specifically, we present the basic definitional approach and its variants, results regarding the power of zero-knowledge proofs as well as recent results regarding questions such as the composeability of zero-knowledge proofs and the use of the adversary's program within the proof of security (i.e., non-black-box simulation).
