Definition ∞ Verifier Forgery describes the malicious act of creating a fraudulent verification that appears legitimate to a verifier within a cryptographic proof system, despite the underlying statement being false or unproven. This compromises the integrity and trustworthiness of the proof. It represents a critical security vulnerability.
Context ∞ Preventing verifier forgery is paramount in cryptographic systems, especially those employing zero-knowledge proofs, where the verifier must be certain of the proof’s validity without accessing the private data. Ongoing research focuses on designing robust proof systems that are computationally infeasible to forge. This ensures the enduring integrity of decentralized applications and secure computations.
