Inventors include Tuhina Singh; Ashutosh Thakur; and Aditya More.
The application for the patent was published on June 19, 2026, under issue no. 25/2026.
Abstract: A METHOD FOR DERIVING A TRANSIENT CRYPTOGRAPHIC KEY FOR SECURE COMMUNICATION The present disclosure relates to a computer- implemented method for deriving a transient cryptographic key for secure communication without storage or transmission thereof. The method comprises obtaining a microsecond-precision timestamp and geographic coordinates associated with a sender device, and computing astronomical positional parameters of celestial bodies using ephemeris calculations in a sidereal coordinate system. Deterministic angular and positional attributes are derived and selectively filtered using a predefined bitmask into numeric-type and text-type parameters. A temporal salt is generated from the timestamp and a dynamic message parameter. A cryptographic key and initialization vector (IV) are generated by hashing the respective parameter sets with the temporal salt. Encryption and decryption are performed using a symmetric algorithm, wherein the key and IV are discarded after use and independently reproducible at a recipient device.
