CONFIG_ENTROPY_NRF5_BIAS_CORRECTION¶
Enable bias correction (uniform distribution)
Type: bool
Help¶
This option enables the RNG bias correction, which guarantees a uniform distribution of 0 and 1. When this option is enabled, the time to generate a byte cannot be guaranteed.
Direct dependencies¶
ENTROPY_NRF5_RNG && !ENTROPY_NRF_FORCE_ALT && ENTROPY_GENERATOR
(Includes any dependencies from if’s and menus.)
Defaults¶
No defaults. Implicitly defaults to n.
