Abstract
Authenticating a device is contemplated. The authenticating may include generating an authentication sufficient to represent trust in an identity of a device when being provisioned or re-provisioned for network access, reconciling inventory management and/or otherwise performing operations dependent on trust.
Claims20
A method for authenticating trust in an identity of a device, the method comprising:
- determining a non-readable attestation for the device from a non-readable element of the device;
- determining a readable attestation for the device from a readable element of the device;
- determining an authentication for the device based on a comparison of the non-readable attestation and the readable attestation, the authentication being sufficient to indicate trust in an identity of the device.
A non-transitory computer-readable medium having a plurality of instructions executable with a processor of a trusted authority for authenticating trust in an identity of a device, the plurality of instructions being sufficient for:
- generating an attestation for the device;
- communicating the attestation for use with a readable element and a non-readable element of the device;
- and
- subsequently generating an authentication for the device based on a comparison of the attestation following receipt from the device and another device in proximity thereto, the another device obtaining the attestation from the readable element, the authentication indicating trust in an identity of the device when the comparison indicates the attestations received from both the device and the another device matching and mistrust in the identity of the device when the comparison indicates the attestations received from both the device and the another device failing to match.
An authentication system comprising:
- a trusted authority for generating an attestation;
- an unidentified device having the attestation included with a readable element and a non-readable element;
- an identified device reading the attestation from the readable element;
- and
- wherein the trusted authority generates an authentication for use at the identified device in assessing trust in an identity of the unidentified device based on a comparison of the attestations included on the non-readable element to the attestation read with the identified device from the readable element.
