A plurality of clients including a platform () and at least one client () communicate with each other in accordance with a publish-subscribe model. A topic common key manager () of the platform () provides, to the client (), a topic common key associated with a topic and being for encryption and decryption of a message directed to the topic. A message manager () transmits the message encrypted with the topic common key associated with the topic, and decrypts a received message with the topic common key associated with the topic. A topic common key storage () of the client () stores the topic common key provided from the platform () in association with identification information of the topic. A message manager () transmits the message encrypted with the topic common key, and decrypts a received message with the topic common key.

Data distribution system, data processing device, and program

A data processing apparatus () includes multiple data processors () that each perform a set subprocess of multiple sequential subprocesses included in a process sequence and a data distributor () that mediates data exchange between the multiple data processors () in accordance with a publish-subscribe model. An ID checker () determines, based on identification information assigned to received data received from the data distributor (), whether received data is to be processed in the subprocess set to be performed by the data processor (). A data processing executor () performs the set subprocess when the ID checker () determines that the received data is to be processed in the set subprocess. A data converter () assigns new identification information to data resulting from the set subprocess performed by the data processing executor () and transmits the data assigned with the new identification information to the data distributor ().

Data processing system, data processing apparatus, and recording medium

A data processing apparatus executes a process on each piece of data repetitively transmitted from a device and transmits processing information on the process to a receiving apparatus, and includes an outputter and a GW communicator. The outputter acquires conditional information, indicating whether a transmission condition required for transmission of generation data generated in execution of the process to the receiving apparatus is satisfied, after every generation of generation data. When the conditional information indicates satisfaction of the transmission condition for the piece of generation data, the outputter outputs additional information on satisfaction or dissatisfaction of the transmission condition for at least one of another piece of generation data generated immediately before or after the piece of generation data. The GW communicator transmits the processing information including the generation data for which the condition is satisfied and the additional information to the receiving apparatus.
