Abstract: In order to ensure security even when packet communication is performed using a plurality of communication paths of a public network, the communication system (1) has a configuration wherein: the transmitter (2) includes a first storage unit (11) that stores a first communication pattern, first and second communication units (12, 13) that perform packet communication with a receiver (3), and a first processor (16) that controls communication units (12, 13); and the receiver (3) includes a second storage unit (21) that stores a second communication pattern, third and fourth communication units (22, 23) that perform the packet communication with the transmitter (2), and a second processor (26) that controls communication units (22, 23), whereby processor (16) transmits packets from communication units as selected in accordance with the first communication pattern and inserts dummy packets into at least one of the groups of packets to be transmitted, and the second processor (26) restores original data from valid packets, that is, the remaining packets after the dummy packets are removed from the received packets in accordance with the second communication pattern.
