Abstract
A communication system includes a transmitting device group and a receiving device configured to receive data sets. The receiving device is configured to determine reliabilities of the received data sets and manage assignment rates of message authentication codes, which are set for respective types of data sets. The transmitting device group is configured to generate message authentication codes for data sets, and transmit data sets after assigning the generated message authentication codes to the data sets at assignment rates. The receiving device is configured to change, when it is determined that the reliability of a first data set has been reduced, the assignment rate for the first data set to a value greater than that before the change and change the assignment rate for a second data set, which is of a type different from the first data set, to a value less than that before the change.
