HSM Firmware Update Signing and Encryption Method
Summary
USPTO published patent application US20260099319A1 for a method of securing hardware security module firmware updates using dual-signature authentication. The system signs firmware with a private key before and after symmetric encryption, providing layered protection for HSM devices. Inventors: Peter Chung and Bhargavi Nisarga.
What changed
USPTO published patent application US20260099319A1 for a method of securing hardware security module firmware updates through a dual-signature process. The system generates a first signature using a private key, augments the firmware image with this signature, then encrypts the augmented image with a symmetric key and applies a second signature to the encrypted result.\n\nThis publication represents a Notice of a patent application and does not grant enforceable rights. Technology companies developing HSM devices or firmware update mechanisms should monitor the prosecution of this application to assess potential future patent claims and competitive implications.
What to do next
- Monitor for patent grant status
- Review product development for potential infringement

HARDWARE SECURITY MODULE FIRMWARE UPDATE
Application US20260099319A1 Kind: A1 Apr 09, 2026
Inventors
PETER CHUNG, BHARGAVI NISARGA
Abstract
A non-transitory machine-readable medium having machine-readable instructions including a firmware generator, the machine-readable instructions for the firmware generator being executable by a processor core to perform operations including signing a firmware image for a hardware security module (HSM) with a private key of a public private key pair to provide a first signature and augmenting the firmware image with a header that includes the first signature to provide an augmented firmware image. The operations further include encrypting the augmented firmware image with a symmetric key to provide an encrypted augmented firmware image. Furthermore, the operations include signing the encrypted augmented firmware image with the private key to provide a second signature and augmenting the encrypted augmented firmware image with the second signature to provide a firmware package for the HSM.
