description A communication system according to an embodiment includes an edge device generating edge data and a service device making use of the edge data. The edge device generates a message authentication code by using a shared key shared with the service device. The edge device transmits first communication data representing communication data in which the message authentication code is assigned to the edge data. The service device verifies source of generation of the edge data included in the first communication data. The verification is performed in accordance with verification result of verifying the message authentication code included in the first communication data by using a shared key shared with the edge device.
