Description

This function verifies the device code provided by the Digipass device using the master activation application data. It also extracts in case of SUCCESS:

Digipass device ID
Digipass device type

It is only applicable to hardware or software Digipass authenticators compliant with the multi-device two-step activation (in the context of multi-device licensing). For more information, refer to the Authentication Suite Server SDK Product Guide.

If a challenge has been used to generate the Activation Message 1 (AALGenMessageActivation1) received by the Digipass device, the same challenge is necessary to validate the device code.

Score-based Digipass

For Digipass devices that integrate the score-based algorithm, Authentication Suite Server SDK performs a score-based authentication to validate the device code. This allows retrieving the Digipass scoring value. Once Authentication Suite Server SDK has successfully validated the device code, it returns either SUCCESS or SUCCESS with the relevant scoring warning code.. See the list of return codes in Table: Return codes (AAL2VerifyDeviceCodeICSF) for more details.

Parameters

Table: Parameters (AAL2VerifyDeviceCodeICSF)
Type	Name	Use	Description
TDigipassBlob	DPMAData	I/O	Digipass master activation application BLOB of the Digipass serial number license that will be used for the activation. Upon return from the function call, this BLOB must be rewritten to the application database to reflect changes.
TKernelParms *	CallParms	I	Structure of runtime parameters to use during this function call.
aat_ascii *	aStorageKeyNameIn	I	String of up to 64+1 characters, left-justified, null-terminated, or right-padded with spaces. This is the label of the ICSF storage key used to encrypt the sensitive Digipass application BLOB data.
aat_ascii *	aInitialVectorIn	I	String of 16 hexadecimal characters, left-justified, null-terminated, or right-padded with spaces. This is the initial vector used to encrypt the sensitive authenticator application BLOB data.
aat_ascii *	Challenge	I	Optional string of 16 numeric or hexadecimal characters, left-justified, null-terminated, or right-padded with spaces. This parameter must hold the challenge that was used initially to generate Activation Message 1. If no challenge was used to generate Activation Message 1, this parameter must be NULL.
aat_ascii *	DeviceCode	I	String of up to 26+1 characters, null-terminated. It contains the device code generated by the Digipass device.
aat_ascii *	DeviceID	O	Output string of 8+1 hexadecimal characters, null-terminated. If the device code has been successfully verified, this parameter contains the value of the Digipass device ID.
aat_int32 *	DeviceIDLength	I/O	In input, this parameter must indicate the size of the allocated buffer for the DeviceID parameter (recommended 9 bytes). In output, this parameter indicates the length of the DeviceID string (without the null-terminated character).
aat_int32 *	pDeviceType	O	In output, this parameter contains the Digipass device type if the device code has been successfully verified (from 0 to 31).
