Non-Interactive Zero Knowledge Proofs in the Random Oracle Model
FS transform NIZK random oracle model
font style='font-size:12px;'>
2019/8/22
The Fiat-Shamir (FS) transform is a well known and widely used technique to convert any constant-round public-coin honest-verifier zero-knowledge (HVZK) proof or argument system CIPC=(Prov,Ver)CIPC=(P...
