    摘要: [Object] To provide a communication system that makes it possible to improve security.
    [Solution] Provided is a communication system including: a first device configured to transmit encrypted information that is encrypted by using a first encryption key; and a second device configured to execute a predetermined process based on the encrypted information obtained from the first device, and a second encryption key that is common to the first encryption key. The first device includes a first change section configured to change the first encryption key in the case where a first condition is satisfied. The second device includes a second change section configured to change the second encryption key in the case where a second condition is satisfied, the second condition being common to the first condition.

    摘要: To manage a series of processes performed by a plurality of devices more efficiently.
    There is provided a control device comprising: a control unit configured to transmit an execution instruction to execute a prescribed process which is a process prescribed in advance to at least one of processing devices and cause the plurality of processing devices including the processing device to execute the prescribed process, wherein, when the control unit detects that an error has occurred in execution of the prescribed process executed by one of the plurality of processing devices, the control unit executes control such that an interruption instruction to interrupt the execution of the prescribed process reaches at least one of the processing devices different from the processing device in which the error has occurred.
