Verifying user premises equipment identity with deployed firmware and expired authentication

A computing system, comprising:

• one or more processor devices configured to:
• receive an authentication request from a User Premises Equipment (UPE), wherein the authentication request is responsive to expiration of a prior authentication certificate provided to the UPE, and wherein the authentication request comprises a set of metadata information elements;
• select a subset of metadata information elements from the set of metadata information elements, wherein the subset of metadata information elements comprises:
• a static metadata information element descriptive of a UPE establishment event that occurred prior to provision of the prior authentication certificate to the UPE;
• and
• a plurality of environmental metadata information elements indicative of a physical environment of the UPE;
• access validation information descriptive of the UPE establishment event to validate the static metadata information element;
• generate a trust score for the UPE based on a comparison between the plurality of environmental metadata information elements and a UPE environmental profile descriptive of a known physical environment of a geographic area associated with the UPE;
• and
• provide an authentication certificate to the UPE based on the trust score being greater than a threshold trust score.

A non-transitory computer-readable storage medium that includes executable instructions configured to cause one or more processor devices to:

• receive an authentication request from a User Premises Equipment (UPE), wherein the authentication request is responsive to expiration of a prior authentication certificate provided to the UPE, and wherein the authentication request comprises a set of metadata information elements;
• select a subset of metadata information elements from the set of metadata information elements, wherein the subset of metadata information elements comprises:
• a static metadata information element descriptive of a UPE establishment event that occurred prior to provision of the prior authentication certificate to the UPE;
• and
• a plurality of environmental metadata information elements indicative of a physical environment of the UPE;
• access validation information descriptive of the UPE establishment event to validate the static metadata information element;
• generate a trust score for the UPE based on a comparison between the plurality of environmental metadata information elements and a UPE environmental profile descriptive of a known physical environment of the UPE;
• and
• provide an authentication certificate to the UPE based on the trust score being greater than a threshold trust score.
