MUMBAI, India, Aug. 17 -- Intellectual Property India has published a patent application (202641096651 A) filed by Vellore Institute Of Technology on August 10, 2026, for A Cryptographic System And Method For Automatic Invalidation Of Misused Encrypted Messages.
Inventors include Ramya G; Siddharth Goutam Kumar; Yash Kumar Singh; and Raghav.
The application for the patent was published on August 14, 2026, under issue no. 33/2026.
Abstract: The present invention relates to a cryptographic communication system for automatic invalidation of encrypted messages. The system comprises an encryption module configured to generate a self-invalidating encrypted message (100) using entropy-dependent cryptographic parameters, a cryptographic workflow (102) configured to associate the encrypted message with contextual entropy verification conditions, and an entropy-bound encrypted message workflow (104) configured to evaluate entropy continuity during message reconstruction. A reconstruction engine conditionally permits decryption only when predefined entropy verification conditions are satisfied during authorized reconstruction. Entropy mismatch conditions generated dueto unauthorized messagereconstruction condition duplicated ciphertext injection, or abnormal reconstruction-state deviations cause automatic invalidation of decryption capability. The disclosed architecture enables entropy-dependent cryptographic reconstruction without requiring centralized deletion infrastructure, synchronized timing systems, or external expiration management mechanisms. The invention further provides misuse-sensitive reconstruction verification for encrypted message security.
