Abstract
According to one embodiment of the present disclosure, an approach is provided in which a diagnostic system retrieves encrypted utilization data from an electronic system that were generated from utilization data corresponding to the electronic system's usage. The diagnostic system decrypts the encrypted utilization data and determines whether the decrypted utilization data are valid. When the decrypted utilization data are valid, the diagnostic system displays the decrypted utilization data on a display. In another embodiment, the diagnostic system retrieves cryptographically-protected utilization data from the electronic system and determines the authenticity of the cryptographically-protected utilization data. Once the cryptographically-protected utilization data are authenticated, the diagnostic system displays the corresponding utilization data on a display.
