Proofs, Arguments, and Zero-Knowledge笔记
2024年5月6日星期一(Day 1,P1-P11):
- interactive proofs (IPs) and arguments之间区别是:arguments (but not IPs) permit the existence of “proofs” of incorrect statements, so long as those “proofs” require exorbitant computational power to find.
- zk-SNARK: Succinct Non-interactive Arguments of Knowledge。zk-SNARK的解释:“Succinct” means that the proofs are short. “Non-interactive” means that the proof is static, consisting of a single message from the prover. “Of Knowledge” roughly means that the protocol establishes not only that a statement is true, but also that the prover knows a “witness” to the veracity of the statement.
- Argument systems的发展包括两个阶段:(1)信息理论上的安全协议,例如:IP,multi-prover interactive proof (MIP), or probabilistically checkable proof (PCP),他们是包含了一个或多个证明者;(2)信息理论安全协议与密码学结合,只有一个
