Interactive Proof Systems

Interactive proof systems involve a back-and-forth exchange between a prover and a verifier to establish the truth of a claim. While less efficient than non-interactive proofs, they are foundational for understanding the theory of zero-knowledge protocols.

In certain high-stakes financial negotiation scenarios, this interaction can be used to ensure that both parties are engaged and providing fresh evidence for their claims. It allows for a dynamic verification process where the verifier can challenge the prover in real-time.

This model is essential for formalizing the security requirements of complex cryptographic interactions.
