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.
