Communication system, information processing device, information processing method, and computer program product

An information processing method implemented by a computer generating edge data, the information processing method comprising:

• generating a message authentication code by using a shared key shared with the service device;
• and
• transmitting first communication data representing communication data in which the message authentication code is assigned to the edge data.

A computer program product comprising a non-transitory computer-readable recording medium on which a computer program executable by a computer is recorded, the computer program instructing the computer to:

• generate a message authentication code by using a shared key shared with the service device;
• and
• transmit first communication data representing communication data in which the message authentication code is assigned to the edge data.

An information processing device connected to an edge device via a first network and connected to a service device via a second network, the edge device generating edge data, the service device making use of the edge data, the information processing device comprising:

• one or more hardware processors coupled to a memory, the one or more hardware processors being configured to transmit, to the service device, communication data received from the edge device, the communication data being data in which a message authentication code generated by using a shared key shared with the edge device has been assigned to the edge data.

An information processing device making use of edge data generated by an edge device, the information processing device comprising:

• one or more hardware processors coupled to a memory, the one or more hardware processors being configured to verify source of generation of the edge data included in communication data in which a message authentication code is assigned to the edge data, the verification being performed in accordance with verification result of verifying the message authentication code included in the communication data by using a shared key shared with the edge device.
