PROBLEM TO BE SOLVED: To provide a wireless communication system capable of accurately generating private keys by preventing mulfunction of wireless apparatuses. SOLUTION: The wireless communication system 100 is provided with wireless apparatuses 10, 30, an antenna 11, and an array antenna 20. The wireless apparatuses 10, 30 extract n-sets of radio wave strengths equal to or more than a threshold value whereby communication with the opposite party can be established and within the dynamic range of the wireless apparatuses 10, 30 from p-sets of radio wave strengths corresponding to p-sets of received radio waves by receiving p-sets of the radio waves from the opposite party while changing the beam pattern of the array antenna 20 into p sets of beam patterns after establishing communication with the opposite party. Then the wireless apparatuses 10, 30 apply multi-value processing to n-sets of the extracted radio wave strengths to generate the private keys Ks1, Ks2. COPYRIGHT: (C)2006,JPO&NCIPI
