Abstract: Digital certificates include pointers to remote certificate information stores that maintain usage information associated with digital certificates. The pointers provide a mechanism for enabling the remote certificate information stores to be queried for usage information associated with a particular digital certificate. The usage information can be used to determine a validity of the digital certificate.

Abstract: A device, having executed a single sign-on operation, may maintain a private device key in volatile memory. A client application may request an authentication artifact as part of obtaining authentication credentials for the device. Responsive to the request, an artifact may be signed with the private device key to generate the requested authentication artifact. The single sign-on operation may be authenticated using an authentication device and a wrap key generated and applied by a secure cryptographic processor using an identifier based on an attestation certificate obtained from the authentication device after successful authentication. The wrap key may be used to decrypt the private device key stored on a persistent device storage.
