CONFIG_HW_UNIQUE_KEY

Hardware Unique Keys (HUK)

Type: bool

Help

This option will load the Hardware Unique Key (HUK) in the KDR
registers of the CryptoCell peripheral and sets the LCS. It will also
lock its flash page so that it's not accesible by the CPU until the
next reboot.

Direct dependencies

(HAS_HW_NRF_CC310 || HAS_HW_NRF_CC312) && NRF_CC3XX_PLATFORM && NRF_SECURITY && !ARM_NONSECURE_FIRMWARE && MPU_ALLOW_FLASH_WRITE

(Includes any dependencies from ifs and menus.)

Defaults

No defaults. Implicitly defaults to n.

Symbols selected by this symbol
