Table 2 Comparative Analysis of IZKPs and NIZKPs
Feature/type | IZKPs | NIZKPs |
|---|---|---|
Interactivity | Involves back-and-forth communication between the prover and verifier | Relies on a single message from the prover to the verifier without further interactions |
Proof Generation | Proof generation hinges on an interactive exchange protocol | Allows for one-step proof generation by the prover |
Process | Characterized by a sequence of challenge-response interactions | Noted for offering computational advantages, minimizing interactive overhead |
Versatility | Widely foundational, forming the basis for many cryptographic protocols | Often evolve from IZKPs via specific transformations |
Security | Founded on diverse cryptographic assumptions and predicated on both parties adhering to the protocol during interaction | Built on certain assumptions, especially those pertaining to the non-interactive transformation. Some may also depend on trusted setups |
Efficiency | Can be less efficient due to potential multiple rounds of communication | Highly efficient in contexts where ongoing interaction is impractical or resource intensive |
