Zero-Knowledge twenty years after its invention
Authors: Oded GoldreichAbstract:
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
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).
