Product Overview

Hardware Security Module (HSM) for secure programming of STM32 products and to avoid product counterfeiting at contract manufacturers' premises. The SFI feature allows secure loading of customer firmware to STM32 products embedding a secure bootloader. After defining the firmware encryption key and encrypting their firmware, the original equipment manufacturer (OEM) stores the encryption key to one or more STM32HSM-V1 HSMs and sets the number of authorized SFI operations (counter value) using the STM32CubeProgrammer and STM32 Trusted Package Creator software tools. Contract manufacturers must utilize the STM32HSM-V1 HSMs to load encrypted firmware to STM32 devices: each HSM only allows the OEM-defined number of programming operations before being irreversibly deactivated.
  • 300 maximum counter value
  • Genuine firmware identification (firmware identifier)
  • Identification of STM32 products with secure firmware install (SFI) functionality
  • Management of ST public keys associated with the supported STM32 products
  • License generation using a customer-defined firmware encryption key
  • Secure counter that generates a predefined number of licenses
  • Direct support for STM32CubeProgrammer software including STM32 trusted package creator tool
