Abstract
Some embodiments provide systems and methods for confidentially and securely provisioning data to an authenticated user device. A user device may register an authentication public key with an authentication server. The authentication public key may be signed by an attestation private key maintained by the user device. Once the user device is registered, a provisioning server may send an authentication request message including a challenge to the user device. The user device may sign the challenge using an authentication private key corresponding to the registered authentication public key, and may return the signed challenge to the provisioning server. In response, the provisioning server may provide provisioning data to the user device. The registration, authentication, and provisioning process may use public key cryptography while maintaining confidentiality of the user device, the provisioning server, and then authentication server.
