This research proposes a Unified Quantum-Resilient Blockchain–Zero-Knowledge Proof Privacy Authentication Framework (QBC-ZKPAF) designed to strengthen security, privacy, and authentication in Internet of Things (IoT) environments. The proposed framework combines blockchain technology, Zero Trust Architecture (ZTA), post-quantum cryptography, and Zero-Knowledge Proofs (ZKPs) to provide secure communication, privacy-preserving authentication, and effective access control. A hybrid Reinforcement-Lattice Blockchain Key Generation mechanism is employed to generate quantum-resistant cryptographic keys, while a Deep Q-Network Multi-Factor Secure Key (DQN-MFSK) mechanism dynamically selects secure keys based on authentication requirements and network conditions. Zero-Knowledge Proof-based signatures further protect sensitive information by enabling authentication without revealing confidential data.
The immutable blockchain ledger records device interactions, access requests, and data transactions in a tamper-resistant manner, thereby improving transparency, traceability, auditability, and post-event forensic analysis. In the event of suspicious activity or security breaches, the framework supports accurate source identification through a tracing key maintained by the audit server within the Zero Trust Architecture. By decentralizing identity management and incorporating multi-factor authentication, QBC-ZKPAF provides enhanced protection against conventional cyber threats as well as emerging quantum-based attacks. Experimental evaluation demonstrates promising performance, achieving 98% privacy preservation, 700 transactions per second (TPS), a quantum resilience score of 0.98, and 96% access control effectiveness. These results indicate that the proposed framework is a reliable and efficient solution for securing modern IoT and blockchain-based applications.
