The research reveals that the path validation scheme with constant-size proof is not unforgeable, as adversaries can forge valid proofs with a significant probability.
We analyze a path validation scheme with constant-size proof (published in IEEE Transactions on Information Forensics and Security) and demonstrate that this scheme fails to achieve unforgeability. An adversary can forge a valid proof with a non-negligible probability.
