MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641049562 A) filed by Dayananda Sagar Academy Of Technology & Management, Bengaluru, Karnataka, on April 18, for 'multi-source physical entropy apparatus with adaptive feedback for cryptographic random number generation.'
Inventor(s) include Dr. P. Mano Paul; M. Sahana Sharma; Priyanka R; Priyanka V Gudada; Manikanta S; Darshan K J; and Likhith Y.
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: "An adaptive multi-source physical entropy generation apparatus for cryptographic random number production comprises a sealed entropy chamber containing heterogeneous granular particles, silica grains, ferromagnetic beads subjected to simultaneous mechanical actuation, electromagnetic disturbance, gravitational particle flow, and optical illumination generating continuous chaotic multi-physics interaction. A multi-sensor array comprising a high-speed CMOS image sensor, magnetic field sensor, vibration sensor, and light intensity sensor captures real-time entropy signals from independent physical processes. An embedded processing unit performs frame-difference analysis, noise sampling, timestamp mixing, and multi-channel bit-level combination, followed by SHA-2 or SHA-3 cryptographic hashing to produce a statistically uniform true random bitstream. Closed-loop adaptive feedback controller continuously evaluates entropy quality through statistical randomness tests and autonomously adjusts mechanical vibration speed, electromagnetic field intensity, particle flow rate, and optical illumination to restore chaotic behavior without manual intervention, ensuring uninterrupted cryptographic-grade random number output suitable for hardware security modules, cryptographic key generation, and authentication systems."
