摘要： A communication device according to one embodiment includes one or more hardware processors. The processors serve to acquire, from at least one electronic device, output data output from the electronic device. The processors serve to communicate with a server device by a communication technique in which numbers indicating communication timings are synchronized. The processors also serve to transmit, to the server device as a destination, the output data in association with a first number out of the numbers. The first number indicates a timing at which the output data is acquired.

摘要： A wireless communication device according to an embodiment includes one or more hardware processors. The one or more hardware processors: collect forwarding load information about wireless communications in a wireless multi-hop network; determine, based on the forwarding load information, a degree of forwarding priority for a packet corresponding to a forwarding determination target; perform a forwarding control such that the packet corresponding to the forwarding determination target is forwarded earlier as the degree of forwarding priority is higher; and, when the packet corresponding to the forwarding determination target is forwarded, transmit the packet corresponding to the forwarding determination target by multi-cast communications or broadcast communications.

摘要： According to an embodiment, a communication system includes a key management server device including a first processor and a router including a second processor. The first processor is configured to: share a bit string by quantum key distribution; receive a control signal including key identification information and a key length; generate a decryption key corresponding to the encryption key from the bit string based on the key identification information and key length upon receiving the control signal without waiting for a request to generate the decryption key from the router; and supply the decryption key to the router. The second processor is configured to: receive a packet encrypted with the encryption key; and decrypt the packet by using the decryption key supplied from the key management server device without requesting the key management server device to generate the decryption key.

摘要： According to an embodiment, a communication device includes one or more processors. The processors share encryption keys with a plurality of external communication devices. The processors, based on residual quantities of the encryption keys, decide on a route for sending transmission data. The processors encrypt, for each external communication device of one or more external communication devices included in the route, a header in which the external communication device is set as a destination, using an encryption key shared with the external communication device. The processors generate a packet that includes the transmission data and encrypted headers for the one or more external communication devices. The processors send the generated packet along the route.
