Abstract:
(EN) Provided is an authentication technology which is far safer than common technologies employing one-time passwords. A client and a server both have a functionality for generating the same solution under the same conditions. The client creates a first 20-character mixed alphanumeric solution (S1002), generates a partial solution in which part of the solution has been extracted in accordance with certain rules (S1003), and transmits the partial solution to the server together with identifying information, i.e. a user ID (S1004). The server receives said solution and information (S2001), generates a solution (S2002), and generates a partial solution (S2003). If the partial solution generated by the server matches the partial solution received from the client, the client is authenticated as being legitimate.
(FR) L'invention concerne une technologie d'authentification qui est beaucoup plus sûre que les technologies communes employant des mots de passe à usage unique. Aussi bien un client qu'un serveur possèdent une fonction visant à générer la même solution dans les mêmes conditions. Le client crée une première solution alphanumérique mélangée de 20 caractères (S1002), génère une solution partielle dans laquelle une partie de la solution a été extraite conformément à certaines règles (S1003), et transmet la solution partielle au serveur conjointement avec des informations d'identification, c'est-à-dire un identifiant d'utilisateur (S1004). Le serveur reçoit ladite solution et les informations (S2001), génère une solution (S2002) et génère une solution partielle (S2003). Si la solution partielle générée par le serveur correspond à la solution partielle reçue en provenance du client, le client est authentifié comme étant légitime.
(JA) 一般的なワンタイムパスワードを用いた技術よりも更に安全性の高い認証技術を提供する。 クライアントとサーバはともに、同じ条件下では同じ解を生成する機能を持つ。クライアントは、20桁の英数字混じりの一つ目の解を作り(S1002)、解の一部をある規則により抜き出した一部解を生成し(S1003)、一部解をユーザIDである識別情報とともにサーバに送る(S1004)。サーバはそれらを受信し(S2001)、解を生成し(S2002)、一部解を生成する(S2003)。サーバで生成した一部解がクライアントから送られてきた一部解と一致したら、そのクライアントが正当なものだと認証する。
