MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202641068282 A) filed by Vellore Institute Of Technology, Chennai on May 27, 2026, for System And Method For Quantum-Resilient Decentralized Identity And Authentication Using Post-Quantum Cryptography.
Inventors include G. Logeswari; K. Tamilarasi; Derrick Samuel R; and Tarun Srikumar.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: The present disclosure provides a system (102) and method (300) for quantum-resilient decentralized identity and authentication using post-quantum cryptography. The system (102) receives transaction data associated with a user. The system (102) encrypts the transaction data using one or more quantum-resistant cryptographic keys. The system (102) transmits the encrypted transaction data to a blockchain network (402) using a quantum-secure communication protocol. The system (102) verifies the one or more quantum- resistant cryptographic keys using a quantum-secure consensus mechanism for decrypting the encrypted transaction data. The system (102) detects, via a machine learning engine (214), one or more anomalies generated during the transmission of the encrypted transaction data. The system (102) utilizes one or more privacy preserving mechanisms to allow processing of the encrypted transaction data.
