 note = {近年様々な端末を使って様々なサービスが受けられるようになってきた．たとえば，外出時には携帯電話端末で社内業務を行い，帰社後は，大きな画面の PC で引き続き業務を継続できると便利である．しかし，現状では帰社後に PC で再び認証を受ける必要があった．本論文では，社外から社内サーバを利用する業務形態において，外出時には携帯電話端末を利用し，帰社後には PC を利用する場合に，ユーザが端末を切り替える際の認証方式を提案する．具体的には，認証済みの情報としての Cookie 情報を引き継ぐことによって，旧端末から新端末に切り替えたときに，サーバ側の認証を簡略化する方法を提案し，提案に基づいたシステムを開発し性能を評価する．, Recently, a lot of users have come to use the cellular phone terminal. Moreover,a variety of electronic equipment have come to be connected continuously with a high-speedbroadband line. In such a situation, it is convenient that service is received with the cellularphone terminal when we go out, and service is received continuously by a PC of a large screenafter we come office. It is more convenient if the authentication of PC becomes unnecessary afterthe cellular phone is authenticated. In this paper, we propose the authentication method whenthe user switches the terminal in the environment that the user receives service with a terminalfrom server. Concretely, we develop and evaluate the system to simplify the authentication ofthe server side when switching from an old terminal to a new terminal by succeeding the cookieas authenticated information.},
