Forward Secrecy and ZKP Hardening in Blockchain-Based IoT Identity: Vulnerability Analysis and Lightweight Redesign
Patidar et al.'s blockchain-based protocol with zero-knowledge proofs offers privacy but lacks thorough security analysis. We identify three vulnerabilities: replay-prone proof binding, trusted-setup compromise, and absent forward secrecy. Our hardened redesign incorporates ephemeral Diffie-Hellman, deterministic nonce binding, and transparent setup. Evaluation on 10–500 nodes shows the improved protocol mitigates vulnerabilities while maintaining lightweight efficiency.
