MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202611111775 A) filed by Graphic Era Hill University, Dehradun on September 17, 2026, for A System And Method For Out-Of-Band Cyber-Physical Verification Of Scada Networks Using Rf Channel State Information.
Inventors include Amrita Tiwari; Sachin Bhatt; Aadarsh Dimri; and Divyansh Bisht.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: The invention relates to industrial control system and SCADA security, and provides an out-of-band cyber-physical verification architecture in which a distributed physical sensing mesh of Wi-Fi-enabled microcontroller nodes based on ESP32 SoC architectures measures CSI telemetry from 802.11 OFDM propagation interacting with a target machine, while an edge AI aggregator separately receives mirrored SCADA traffic through a passive network intercept. The edge AI aggregator, using segregated NIC-A and NIC-B, decrypts AES-128 protected CSI telemetry, applies phase calibration to suppress Carrier Frequency Offset and Sampling Frequency Offset artifacts, Hampel filtering, Principal Component Analysis, and machine learning classification using a 1D Convolutional Neural Network or Support Vector Machine to derive State_phys, and performs deep packet inspection and semantic protocol parsing of Modbus TCP, DNP3, or IEC 104 traffic to derive State_dig. Asynchronous comparison identifies cyber-physical mismatch events for alerting or hardwired relay isolation, without insertion inline in the control loop.
