MUMBAI, India, July 30 -- Intellectual Property India has published a patent application (202641088533 A) filed by Venkatesan R; Yasmin A; and Gaverchand K on July 20, 2026, for State–stack Based Text Encryption Method Using A Self-Evolving Pushdown Automaton.
Inventors include Venkatesan R; Yasmin A; and Gaverchand K.
The application for the patent was published on July 24, 2026, under issue no. 30/2026.
Abstract: The present invention discloses a self-evolving pushdown automaton-based text encryption method for protecting textual information using a dynamically evolving cryptographic framework. The disclosed method integrates computational state transitions, adaptive stack evolution, and dynamic cryptographic parameter generation within a self-evolving pushdown automaton to produce continuously varying character transformations during the encryption process. The coordinated interaction between the computational states and stack memory enables deterministic encryption and corresponding plaintext recovery while introducing dynamic variability into successive encryption operations. The disclosed method provides an efficient cryptographic framework for protecting textual information against unauthorized access and is suitable for implementation in secure communication systems, electronic document protection, cloud computing platforms, Internet of Things (IoT) environments, digital identity management, financial information systems, healthcare information infrastructures, defence communication systems, industrial control networks, and other applications requiring secure processing, exchange, and storage of textual information.
