Abstract

現在のIPプロトコルは、ネットワーク層で暗号化などの安全対策がなされていない。このため、インターネットを経由した遠隔ログインは、システムセキュリティ上の大きな問題となる。このため、S/KEYなどのような使い捨てパスワードを用いたユーザ認証システムが提案されている。本稿では、当研究室におけるOPTシステムの運用結果と、S/KEYによる認証のセッションを組み込んだ端末側ユーザインターフェースのプロトタイプについて報告する。The current IP protocol does not support the encription of the packets at the network layer. This causes some serious difficulties with respect to the system security when the remote logins are done over the Internet. For this purpose, the One-Time Password (OTP) systems, such as the S/KEY system, are proposed. This paper presents an experimental operation of the OTP system in our laboratry, and also discusses a prototype of the user interface of the Telnet client with a built-in OTP based user authentification session.
