Therefore, proposing/implementation of other authentication methods, which are used together with password authentication, are urgent. Meanwhile, CHAP is used a lot of services over the Internet as de facto standard. Therefore, it is not easy to change a new authentication protocol into CHAP. I propose a new method which can send many types of authentication codes using intact CHAP with revising calculation on user terminal and servers. As a result, a multi-factor authentication over existing password-authenticaion protocol can be realized. In addition, I propose a revised method of my proposal using a proxy server because of continuity in services. Furthermore, I structure a test system using proposed method and evaluate performances of it. By using my proposal, other authentication method using password authentication together can be realized with a minimum cost burden.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"2640","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"2627","bibliographicIssueDates":{"bibliographicIssueDate":"2016-12-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"12","bibliographicVolumeNumber":"57"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-19T00:46:04.466957+00:00","id":176426,"links":{}}
