useful P2P environment, we propose an authentication method called AUBReX (Authentication method Using Buddy-buddy relationship Represented by Cross certificate), which supports both anonymity and malicious user identification, for P2P environment. In the AUBReX, a trusted relationship (fellowship, or buddy-buddy relationship) between two users is represented by issuing X.509 cross certificate each other. The cross certificate has a secure-hashed CommonName as an end entity, that can only be revealed between the users. By collecting such anonymous cross certificates via P2P connection and generating a certificate chain and verifying it, the AUBReX provides an authentication mechanism between users who don’t have direct trusted relationship. We have made a sample implementation of the AUBReX and tested basic authentication functionalities with the implementation. With results of the test, we conclude that the AUBReX can be an effective authentication method for our desired P2P environment.","subitem_description_type":"Other"}]},"item_3_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"159","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌コンピューティングシステム（ACS）"}],"bibliographicPageStart":"139","bibliographicIssueDates":{"bibliographicIssueDate":"2008-03-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"SIG2(ACS21)","bibliographicVolumeNumber":"49"}]},"relation_version_is_last":true,"weko_creator_id":"1"}}
