MUMBAI, India, June 22 -- Intellectual Property India has published a patent application (202641068283 A) filed by Cvr College Of Engineering on June 01, 2026, for A Cellular Automata Based Buffer-Free High-Entropy Physical Unclonable Function Authentication System.
Inventors include Esther Rani Thuraka; T Padmavathi; and L. Joy Suneel Raj.
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: The present invention relates to a memoryless Physical Unclonable Function (PUF) based authentication system using Cellular Automata (CA) structures to generate secure and unique signatures. The invention is based on replacing traditional XOR and arbiter-based PUFs with non-linear cellular automata networks comprising configurable Boolean functions, improving randomness and security against machine learning based modelling attacks. The system uses a memory-based entropy source for initial seeds, which are then evolved using cellular automata rules to generate multiple uncorrelated bits of the response without resetting or buffering the memory. It does not need to store keys permanently, requires less memory resources and offers better entropy, randomness and resilience. The design can be used to secure authentication in IoT, embedded and mobile systems.
