WebDec 10, 2011 · Motivated by both theoretical and practical interests, we ask if the prover and verifier of a zero-knowledge proof of knowledge are obfuscatable. Our answer to this question is as follows. First we present two definitions of obfuscation for interactive probabilistic programs and then achieve the following results: WebA 3-round protocol Π =P,V) for a relation R is an interactive protocol played between a prover P and a veriﬁer V on common input x and private input w of P s.t. (x,w) ∈R. In a 3-round protocol the ﬁrst message a and the third message z are sent by P and the second messages c is played by V.Atthe palsinestresWeb2024. CRYPTO.

The technique is based on creating ambiguity in the original circuit by inserting “key” input bits into the circuit such that the circuit is unintelligible absent a …
