Detailed Description

This module includes the platform abstraction for random number generation.

Function Documentation

uint32_t otPlatRandomGet ( void )

Get a 32-bit random value.

This function may be implemented using a pseudo-random number generator.

otError otPlatRandomGetTrue	(	uint8_t *	aOutput,
		uint16_t	aOutputLength
	)

Get true random value sequence.

This function MUST be implemented using a true random number generator (TRNG).

Parameters

[out]	aOutput	A pointer to where the true random values are placed. Must not be NULL.
[in]	aOutputLength	Size of `aBuffer`.

Return values

OT_ERROR_NONE	Successfully filled `aBuffer` with true random values.
OT_ERROR_FAILED	Failed to fill `aBuffer` with true random values.
OT_ERROR_INVALID_ARGS	`aBuffer` was set to NULL.
