phhalHw_Sam_Cmd_SAM_ISOInternalAuthenticate()

phStatus_t phhalHw_Sam_Cmd_SAM_ISOInternalAuthenticate	(	phhalHw_Sam_DataParams_t *	pDataParams,
		uint8_t	bOption,
		uint8_t *	pOptsA,
		uint8_t	bOptsALen,
		uint8_t *	pRndA,
		uint8_t *	pRndALen,
		uint8_t **	ppResponse,
		uint16_t *	pRespLen
	)

Performs Originality Check of SAM .

The authentication is initiated by ISOInternalAuthenticate.

Returns

Status code

Return values

PH_ERR_SUCCESS	Operation successful.
PH_ERR_INVALID_DATA_PARAMS	pDataParams is NULL.
PH_ERR_INVALID_PARAMETER	pOptsA, pRndA, pRndALen and pRespLen are NULL.
Other	Depending on implementation and underlaying component.

Parameters

[in]	pDataParams	[In] Pointer to this layer's parameter structure.
[in]	bOption	[In] Challenge usage (RndA) Generate Challenge internally and exchange Exchange the Challenge provided by user
[in]	pOptsA	[In] PCD Option. Will be exchanged if bOptsALen has a value other than zero User should provide Value field only. Tag and Length will be included internally.
[in]	bOptsALen	[In] Length of bytes available in pOptsA buffer.
[in,out]	pRndA	[In, Out] Authentication Data Object: random challenge from PCD. Empty buffer if Generate Challenge internally is provided in bOption parameter. Will be updated with Random Challenge generated internally. The buffer size should be equal to the RndA size that is expected. Random Challenge if Challenge provided by user is provided in bOption parameter. User should provide Value field only. AuthDOHdr (Tag and Length) will be included internally.
[in,out]	pRndALen	[In, Out] Length of bytes available in pRndA buffer.
[out]	ppResponse	[Out] RndB and Signature returned by SAM.
[out]	pRespLen	[Out] Length pf bytes available in ppResponse parameter.
