摘要：
A wireless ad-hoc communication system in which an attribute certificate can be independently and dispersedly issued is provided. A terminal (B200) transmits a beacon (2011) for participating in a network in the wireless ad-hoc communication system. The beacon (2011) indicates whether or not the terminal (B200) has an attribute certificate. Upon receiving the beacon (2011), a terminal (A100) checks the beacon. If it is determined that the terminal (B200) does not have an attribute certificate, the terminal (A100) transmits an attribute-certificate issuance suggestion message (1032) for suggesting an attribute-certificate issuing request to the terminal (B200). When the terminal (B200) transmits an attribute-certificate issuance request message (2041) in response to this message, the terminal (A100) transmits an attribute-certificate issuance message (1052) to the terminal (B200).
