MUMBAI, India, Jan. 2 -- Intellectual Property India has published a patent application (202541123287 A) filed by Sr University, Warangal, Telangana, on Dec. 6, 2025, for 'multi-layer sybil attack mitigation in vanets via collaborative physical-layer authentication and dynamic trust consensus.'
Inventor(s) include Mrs. K. Shireesha; and Dr. P. Pramod Kumar.
The application for the patent was published on Jan. 2, under issue no. 01/2026.
According to the abstract released by the Intellectual Property India: "[048] A multi-layer Sybil attack mitigation system for Vehicular Ad-Hoc Networks (VANETs) is disclosed, integrating collaborative physical-layer authentication with dynamic trust consensus mechanisms. Vehicles extract radio-frequency signal features to verify authenticity and exchange trust scores to evaluate the reliability of neighboring nodes. By combining instantaneous physical verification with cooperative trust assessment, the system provides real-time detection and mitigation of Sybil nodes, reduces false positives, and operates in a decentralized and scalable manner. The invention enhances the security, reliability, and integrity of VANET communications, supporting safe and trustworthy vehicular networking in dynamic and high-mobility environments."
