Abstract
An information processing apparatus includes: a disk to store data; a transmitting and receiving unit to exchange information with a recovery apparatus over a network; an authentication processor to, when receiving a first authentication key from the recovery apparatus, perform an authentication process based on the first authentication key and a second authentication key; and a writing controller to write an image file to the disk upon the authentication performed by the authentication processor and issue a completion message to the recovery apparatus on completion of the writing.
Claims13
An information processing apparatus comprising:
- a disk to store data;
- a transmitting and receiving unit to exchange information with a recovery apparatus over a network;
- an authentication processor to, when receiving a first authentication key from the recovery apparatus, perform an authentication process based on the first authentication key and a second authentication key;
- and
- a writing controller to write an image file to the disk upon the authentication performed by the authentication processor and issue a completion message to the recovery apparatus on completion of the writing.
A recovery apparatus for remotely recovering a disk of an information processing apparatus, the recovery apparatus comprising:
- a transmitting and receiving unit to exchange information between the information processing apparatus and a key supply apparatus;
- an authentication key acquiring unit to acquire a first authentication key from the key supply apparatus;
- and
- an authentication processor to make a request for authentication to the information processing apparatus based on the first authentication key, receive a notification relating to the authentication from the information processing apparatus, and delete the first authentication key upon a completion message indicating completion of writing an image file to the disk of the information processing apparatus.
A disk recovery method of recovering a disk of an information processing apparatus using a recovery apparatus, the disk recovery method comprising:
- performing an authentication process based on the first authentication key and a second authentication key by the information processing apparatus when receiving a request for authentication based on the first authentication key from the recovery apparatus over a network;
- writing an image file to the disk by the information processing apparatus upon the authentication;
- and
- providing a completion message to the recovery apparatus by the information processing apparatus upon a normal completion of the writing.
