MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202621043796 A) filed by Sage University, Indore, Madhya Pradesh, on April 6, for 'apparatus and method for secure cryptographic key management.'
Inventor(s) include Ms. Sakshi Agrawal; Dr. Prashant Jain; Prof. Pooja Verma; Dr. Mukesh K Yadav; and Shreyansh Pandey.
The application for the patent was published on May 29, under issue no. 22/2026.
According to the abstract released by the Intellectual Property India: "An apparatus (100) for secure cryptographic key management includes a multi-zone tamper-responsive enclosure (102), a noise injection controller (104) and an internal voltage regulator (106) configured to superimpose pseudo-random current variations on the external power input, a zeroization controller (108) configured to discharge a secure volatile memory through a hardware erasure path. A processor (110) is operatively coupled to the multi-zone tamper-responsive enclosure (102), the noise injection controller (104), and the zeroization controller (108). The processor (110) increases a noise output level of the noise injection controller (104) upon receiving outer zone tamper signals, suspends cryptographic operations upon receiving mid zone tamper signals, activates the zeroization controller (108) upon receiving inner zone tamper signals, and authorizes a cryptographic key operation upon receiving a predetermined number of valid authentication responses within a preconfigured time period from a plurality of electrically isolated smart card reader interfaces (112)."
