Functions
int	TOFSecurity_close (tofSecHandle_t *tofSecHandle)
	This function is used to close ToF Security and free buffers. More...
int	TOFSecurity_genSeed (tofSecHandle_t *tofSecHandle)
	use TRNG HW module to generate a true 128-bit random seed More...
int	TOFSecurity_genSyncWords (tofSecHandle_t *tofSecHandle, uint8_t bufferToFill)
