This figure illustrates a schematic diagram of the interaction between subsystems. There are four states : device register, integrity generation, attestation verification, and recovery DB store.
I want to point out the object recovery and saving verification results phases, which is recovery DB store state.
The RAS RA server subsystem compares the individual verification information received from the device with the individual verification information stored when the device is registered, checks whether the object is damaged, and requests recovery from the trusted device element (steps 17 and 18).
After performing full or individual recovery on the detected damaged object, remote verification information is created and delivered to the RAS RA server subsystem (steps 19, 20, 21, and 22).
