MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641048275 A) filed by Nehru Memorial College, Tiruchirappalli, Tamil Nadu, on April 15, for 'quantum-resistant multi-layer authentication protocol for securing large-scale iot communication networks.'
Inventor(s) include Dr. V. Umadevi; Dr. D. Jayadurga; Dr. M. Dhivya; and Dr. S. Bhuvana.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a quantum-resistant multi-layer authentication protocol for securing large-scale Internet of Things (IoT) communication networks. The system provides a scalable and adaptive framework that integrates multiple layers of device verification, including identity authentication, session key management, behavioral monitoring, and anomaly detection, ensuring robust protection against both classical and quantum-enabled cyber threats. Lightweight, post-quantum cryptographic algorithms, such as lattice-based encryption, hash-based signatures, and multivariate polynomial schemes, are employed to maintain security while minimizing computational and energy overhead for resource-constrained devices. The protocol supports centralized and decentralized network architectures, dynamic device onboarding and decommissioning, secure session key rotation, and predictive risk assessment. Adaptive communication strategies optimize bandwidth usage and latency, while modular design enables integration with heterogeneous devices and future cryptographic advancements. The invention ensures secure end-to-end communication, continuous verification, and high reliability across large-scale IoT ecosystems, providing a resilient, energy-efficient, and future-proof security solution for critical applications including smart cities, industrial automation, healthcare, and autonomous systems."
