MUMBAI, India, June 30 -- Intellectual Property India has published a patent application (202641075841 A) filed by Vellore Institute Of Technology on June 19, 2026, for System And Method For Trusted Execution Environment (tee)-Anchored Zero Trust Per-Packet Authentication In Electric Vehicle Charging Infrastructure Networks.
Inventors include Ragavan K; and Kalyani Manoj.
The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: A Trusted Execution Environment (TEE)-anchored zero trust per-packet authentication system for securing Vehicle-to-Infrastructure (V2I) communications in electric vehicle charging corridors is disclosed. The system comprises an Electric Vehicle On-Board Unit (101) storing a hardware-bound Vehicle Root Key (VRK), a packet creation and signing module (102), a Vehicle-to-Infrastructure communication channel (103), and a Roadside Unit TEE vault (104) executing a Zero Trust Check module (105). Each communication packet is independently authenticated through registry verification, replay detection, timestamp freshness validation, VRK matching, and cryptographic signature verification. A decision module (106) generates an allow decision (107) or a block decision (108), and authentication outcomes are recorded in a tamper-resistant audit log maintained within the TEE vault. A next RSU handoff module (109) enables decentralized vehicle mobility authentication across charging corridors without central server dependency. The invention provides hardware-rooted trust, continuous packet verification, resistance to spoofing and replay attacks, and immutable forensic accountability.
