Abstract

See full text

When a data processing device is disconnected from a computer system after mutual authentication has been completed between the computer system and the data processing device, the data processing device cancels an authenticated state, and is not able to transfer data to a device other than a specific computer system. Therefore, even when the data processing device is connected to a device other than the specific computer system after the connection of a cable supporting hot swapping has been changed, the data processing device maintains the confidentiality of data.
