Abstract: According to an embodiment, a communication control device includes a communication unit and a jamming control unit. The communication unit wirelessly communicates with a first device and uploads information acquired from the first device to a second device via a network. The jamming control unit allows jamming radio waves to be output to interfere with wireless communication between the first device and a device other than the communication control device, the device being to perform wireless communication in a communication band used by the first device.

Abstract: According to an embodiment, a communication control device includes a plurality of communication systems connected in parallel between a first device and a network communication network, and a distribution controller. The distribution controller is provided between the first device or the network communication network and the communication systems, and configured to execute communication processing in a distributed manner by communication systems of the number corresponding to a processing load on data from the first device or the network communication network. The communication systems each include a controller configured to execute communication processing using a common key determined by a mutual authentication process with the second communication.

Abstract: A wireless device has a first information acquisition part to acquire first information when a first gate is passed through, a second information generator to generate second information by using the first information, a third information acquisition part to acquire third information by a wireless communication using the second information and invalidate the third information after a predetermined time period is elapsed since the third information is acquired, and a service executing part to execute a service by using the third information. An area capable of acquiring the third information by the third information acquisition part is broader than an area capable of acquiring the first information by the first information acquisition part.
