1. An information processing device, comprising:
a communication unit configured to one of:
transmit transmitting data of a frame to an another information processing device; or
receive the transmitting data from the another information processing device based on communication with the another information processing device to perform high-speed data transmission of the transmitting data, wherein the transmitting data includes:
image data in a specific direction between the information processing device and the another information processing device,
an extended packet including an extended packet header and packet data, and
a unique message that notifies at least one of the information processing device or the another information processing device that the image data is in a state different from a normal time or a usual time; and
a protection unit configured to:
derive a session key; and
execute at least one of generation, verification, or decryption of protection data of the unique message, wherein
the image data is stored in the packet data, and
the image data and the unique message are transmitted at different timings through one of a part or whole of a communication path regarding the communication.
 
19. A mobile device, comprising:
an information processing device including:
a communication unit configured to one of:
transmit transmitting data of a frame to an another information processing device, or
receive the transmitting data from the another information processing device based on communication with the another information processing device to perform high-speed data transmission of the transmitting data, wherein the transmitting data includes:
image data in a specific direction between the information processing device and the another information processing device,
an extended packet including an extended packet header and packet data, and
a unique message that notifies at least one of the information processing device or the another information processing device that the image data is in a state different from a normal time or a usual time; and
a protection unit configured to:
derive a session key; and
execute at least one of generation, verification, or decryption of protection data of the unique message, wherein
the image data is stored in the packet data, and
the image data and the unique message are transmitted at different timings through one of a part or whole of a communication path regarding the communication.
 
20. A communication system, comprising:
an information processing device including:
a communication unit configured to one of:
transmit transmitting data of a frame to an another information processing device; or
receive the transmitting data from the another information processing device based on communication with the another information processing device to perform high-speed data transmission of the transmitting data, wherein the transmitting data includes:
image data in a specific direction between the information processing device and the another information processing device,
an extended packet including an extended packet header and packet data, and
a unique message that notifies at least one of the information processing device or the another information processing device that the image data is in a state different from a normal time or a usual time; and
a protection unit configured to:
derive a session key; and
execute at least one of generation, verification, or decryption of protection data of the unique message, wherein
the image data is stored in the packet data, and
the image data and the unique message are transmitted at different timings through one of a part or whole of a communication path regarding the communication.
