Booting system, boot program, and method therefor

A booting system comprising a boot target device and a storage device storing a first object and a second object for booting the boot target device, the boot target device and the storage device being connectable by using at least one interface, the first object and the second object being transferred via boot object transfer paths using at least one of the at least one interface,

• wherein the boot target device comprises:
• a first object loading module for loading the first object transferred via a first boot object transfer path using a first interface from the storage device;
• an interface enabling module for booting the loaded first object to perform processing to make at least one interface functional;
• a transfer path switching module for switching the transfer path to enable at least one boot object transfer path using the interface that has been made functional;
• a second object loading module for loading the second object transferred from the storage device via a second boot object transfer path using any of the at least one functional interface;
• an object boot up module for booting the second object;
• and
• an encryption key exchanging module for causing the storage device and the boot target device to exchange a key used for encryption via the boot object transfer path having a degree of safety higher than a predetermined value when the degree of safety of the boot object transfer path is lower than the predetermined value.

A booting method for a booting system including a boot target device and a boot source device having a first object and a second object for booting the boot target device, the boot target device and the boot source device being connectable by using at least one interface, the first object and the second object being transferred via boot object transfer paths using at least one of the at least one interface,

• the booting method comprising:
• a first transfer step of transferring the first object from the boot source device to the boot target device via a first boot object transfer path using a first interface;
• an interface enabling step of causing the boot target device to boot the first object to make at least one interface functional;
• a transfer path switching step of switching the transfer path to enable at least one boot object transfer path using the interface that has been made functional;
• a second transfer step of transferring the second object from the boot source device to the boot target device via the at least one boot object transfer path;
• an object boot up step of causing the boot target device to boot the second object;
• and
• an encryption key exchanging step of causing the boot source device and the boot target device to exchange a key used for encryption via the boot object transfer path having a degree of safety higher than a predetermined value when the degree of safety of the boot object transfer path is lower than the predetermined value.
