Abstract: In some implementations, a device may transmit, to an authentication server, a certificate signing request (CSR) based on a private key stored on a data logger, wherein the data logger is integrated with a sensor within the device. The device may receive, via the data logger and from the authentication server, a signed device certificate based on the CSR. Additionally, the device may receive, via the data logger and from the authentication server, a signed owner certificate associated with a controller. The device may receive, via the data logger and from the controller, a command signed using the owner certificate. Accordingly, the device may store, in the data logger, measurements from the sensor based on the command. The device may generate a data structure including the stored measurements, wherein the data structure is signed using the signed device certificate. The device may transmit, to the authentication server, the data structure.

Abstract: A method, in a provisioning server, of provisioning a printer, includes: receiving a provisioning request from the printer, the provisioning request containing (i) a printer identifier, and (ii) an account identifier associated with the printer; obtaining, from a digital certificate issuer, a unique string; sending the unique string to the printer; receiving from the printer, in response to sending the unique string, a certificate signing request containing (i) the printer identifier, (ii) the account identifier, and (iii) an authentication token including the unique string signed with a private key of the printer; validating the certificate signing request; passing the validated certificate signing request to the digital certificate issuer; receiving, from the digital certificate issuer, a digital certificate encoding the printer identifier and the account identifier; and providing the digital certificate to the printer for storage.

Abstract: A disclosed example is a server residing on a first network. The server has an observer. The observer receives observational data from a media processing device residing on a second network via a first persistent connection between the media processing device and the server. The observer provides, via the first persistent connection, a configuration file to the media processing device that defines a type of the observational data to be collected by the media processing device. The observer is prevented from communicating an operational instruction to the media processing device. The operational instruction is to control media processing hardware of the media processing device.
