MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641051772 A) filed by MLR Institute Of Technology, Hyderabad, Telangana, on April 23, for 'system and method for quantum-secure email communication using hybrid qkd and post-quantum cryptography.'
Inventor(s) include Ms. Divya Priya Degala; Mr. Gaddam Sudheer Kumar; Mr. Pentala Kishore; and Ms. Hazra.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a system and method for quantum-secure email communication using a hybrid cryptographic architecture integrating Quantum Key Distribution (QKD) and advanced symmetric encryption. The system comprises a web-based frontend interface for composing and receiving emails, a backend application server for request handling and business logic execution, and a core services layer including a QKD module, an encryption engine, and a secure key store. Quantum-secure session keys are generated between communicating parties through a QKD mechanism and are subsequently utilized for encrypting email content using a strong symmetric encryption algorithm such as AES-256. The encrypted messages are transmitted and retrieved via standard SMTP and IMAP protocols through external mail servers, ensuring compatibility with existing email infrastructure. The system further includes secure key lifecycle management, authentication controls, and decryption processes performed within a protected server environment. By combining quantum-based key exchange with robust encryption and practical web integration, the invention provides a scalable and future-resistant solution for protecting email communications against both classical and quantum computing threats."
