Zusammenfassung:PROBLEM TO BE SOLVED: To prevent mutual authentication from taking time in communicating with a plurality of nodes. SOLUTION: This transmitting side node 10 specifies the number of time slots in a node search command, and a plurality of receiving side nodes A and B respectively select an arbitrary time slot and return a search response. After that, when the respective receiving side nodes A and B receive a first mutual authentication command, the receiving side nodes A and B return an authentication 1 response in the time slots selected during the search response. The same processing is performed during receiving a second mutual authentication command. COPYRIGHT: (C)2010,JPO&INPIT
