Abstract
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.
