Abstract: A server receives a certificate signing request and onboarding information for an applicant device, and identifies a customer associated with the applicant device based on an applicant device identifier and a database identifiers associated with customers. The device determines a registered device associated with the customer is a trusted device, a location trust value for the applicant device based on a geolocation proximity between the applicant device and the trusted device, and an environment trust value for the applicant device based on a proximity in a network topology between the applicant device and the trusted device. The device further determines a trust score for the applicant device based on the location trust value and the environment trust value, and sends a signed certificate to the applicant device over the network when the trust score for the applicant device exceeds a threshold.
