Remarks

The provisioning service supports Device Identifier Composition Engine, or DICE, as the device attestation mechanism. To use X509, user must provide the certificate. This class provide the means to create a new attestation for a X509 certificate and return it as an abstract interface Attestation.

An X509 attestation can contains one of the 3 types of certificate:

• Client or Alias certificate: Called on this class as clientCertificates, this certificate can authenticate a single device.
• Signing or Root certificate: Called on this class as rootCertificates, this certificate can create multiple Client certificates to authenticate multiple devices.
• CA Reference: Called on this class as X509CAReferences, this is a CA reference for a rootCertificate that can creates multiple Client certificates to authenticate multiple devices.

The provisioning service allows user to create IndividualEnrollment and EnrollmentGroup. For all operations over IndividualEnrollment with X509, user must provide a clientCertificates, and for operations over EnrollmentGroup, user must provide a rootCertificates or a X509CAReferences.

For each of this types of certificates, user can provide 2 Certificates, a primary and a secondary. Only the primary is mandatory, the secondary is optional.

The provisioning service will process the provided certificates, but will never return it back. Instead of it, GetPrimaryX509CertificateInfo() and GetSecondaryX509CertificateInfo() will return the certificate information for the certificates.
