PROBLEM TO BE SOLVED: To prevent application operation's delay caused by execution of authenticity determination.SOLUTION: A communication system comprises a first communication apparatus and a second communication apparatus. The first communication apparatus 10 comprises an output control unit for performing control of outputting first information showing information to be made to be used by the second communication apparatus and second information to be used for authenticity determination of determining whether or not a transmission source of information is the first communication apparatus 10, so that a frequency for the first information differs from that for the second information and coverage of the second information is wider than that of the first information. The second communication apparatus comprises a first information reception unit, a second information reception unit, an authenticity determination unit, and a use control unit. The authenticity determination unit performs, on the basis of the second information received by the second information reception unit, authenticity determination of determining whether or not a transmission source of the second information is the first communication apparatus. The use control unit, when it is determined as a result of the authenticity determination that the transmission source of the second information is the first communication apparatus 10, performs control of using the first information received within the second information's coverage by the first information reception unit.SELECTED DRAWING: Figure 4 |
