摘要： A method and system for unlocking diagnostic functions in a hardware device for a user. The method obtains a signed permission object for the hardware device, and validates the signed permission object. A memory of the hardware device stores a device identifier and a last recorded sequence number. The signed permission object includes a sequence number and is associated with an expiration counter having an initial value that indicates a lifetime for the signed permission object. When the signed permission object is valid, the method updates the expiration counter to decrease the lifetime of the signed permission object, stores the sequence number associated with the signed permission object as the last recorded sequence number in the hardware device, and unlocks the diagnostic functions for the user based on the signed permission object.
