          <datacite:description descriptionType="Other">インターネット接続のためのアクセスポイントにおける認証方式として IEEE802.1X 認証が利用されているが、現在の方式ではモバイルホストのプライバシー情報が通信事業者に漏洩する問題がある。我々はこの問題を解決するために、ぐるーぷ署名を用いた匿名認証方式を提案し、実装してきた。しかし、この匿名認証方式ではユーザ失効が考慮されていないという問題がある。そこで本稿では、ユーザ失効可能なグループ署名を利用することにより、ユーザ失効機能をもつ匿名 IEEE802.1X 認証の実装を行い、その評価を行う。</datacite:description>
          <datacite:description descriptionType="Other">The IEEE802.1X authentication is used well as an authentication protocol in the Access Point for the Internet connection. There is a problem that mobile host's privacy information is leaked to the Internet service provider in this protocol. To solve this problem, we have proposed and implemented an anonymous authentication using the group signature. However, there is a problem that the user revocation is not considered. In this paper, an anonymous IEEE802.1X authentication with a user revocation is implemented by using a group signature with a user revocation function, and the authentication time is evaluated.</datacite:description>
