Intellectual Property India Publishes Patent Application for 'Novel Approach To Protect Hardware Managed Integrated Cryptographic Engine Keys Efficiently While Preventing Data At Rest Attacks' Filed by Qualcomm Incorporated

MUMBAI, India, Sept. 26 -- Intellectual Property India has published a patent application (202547083312 A) filed by Qualcomm Incorporated, San Diego, on Sept. 2, for 'novel approach to protect hardware managed integrated cryptographic engine keys efficiently while preventing data at rest attacks.'

Inventor(s) include Anumala, Sridhar; Bhuvanagiri, Bharani; Kumar, Nishanth; Athiyappan, Dhananjayan; and Boenapalli, Madhu Yashwanth.

The application for the patent was published on Sept. 26, under issue no. 39/2025.

According to the abstract released by the Intellectual Property India: "Various embodiments include methods implemented in a processor for management of cryptographic keys of an integrated cryptographic engine. Embodiments may include detecting a cryptographic key access control event, determining whether the cryptographic key access control event is for disabling cryptographic key access at a cryptographic key memory of the integrated cryptographic engine, disabling cryptographic key access at the cryptographic key memory in response to determining that the cryptographic key access control event is for disabling cryptographic key access at the cryptographic key memory, and maintaining one or more cryptographic keys at the cryptographic key memory for which cryptographic key access is disabled. Embodiments may further include enabling cryptographic key access at the cryptographic key memory in response to determining that the cryptographic key access control event is not for disabling cryptographic key access at the cryptographic key memory."

The patent application was internationally filed on Mar. 05, 2024, under International application No.PCT/US2024/018505.
