getAuthenticatedData
Returns a CBOR structure containing the retrieved data.
This structure - along with the session transcript - may be cryptographically authenticated to prove to the reader that the data is from a trusted credential and getMessageAuthenticationCode can be used to get a MAC.
The CBOR structure which is cryptographically authenticated is the DeviceAuthenticationBytes structure according to the following CDDL schema:
DeviceAuthentication = [
"DeviceAuthentication",
SessionTranscript,
DocType,
DeviceNameSpacesBytes
]
DocType = tstr
SessionTranscript = any
DeviceNameSpacesBytes = #6.24(bstr .cbor DeviceNameSpaces)
DeviceAuthenticationBytes = #6.24(bstr .cbor DeviceAuthentication)

where
DeviceNameSpaces = {
* NameSpace => DeviceSignedItems
}
DeviceSignedItems = {
+ DataItemName => DataItemValue
}
NameSpace = tstr
DataItemName = tstr
DataItemValue = any

The returned data is the binary encoding of the DeviceNameSpaces structure as defined above.
Return
The bytes of the DeviceNameSpaces CBOR structure.
