AUTHENTIFIZIERUNGSVERFAHREN UND -SYSTEM EINES KUNDENENDGERÄTS DURCH EINEN ZIELSERVER MITHILFE EINER TRIANGULATION ÜBER EINEN AUTHENTIFIZIERUNGSSERVER
A method of authenticating a client terminal (C) is proposed by a target server (A), comprising the following steps: the client terminal (C) authenticates with an authentication server (B); the target server (A) authenticates with the authentication server (B); the authentication server (B) and the target server (A) share a password for the client terminal (C); the authentication server (B) transmits the password to the client terminal (C); the client terminal (C) transmits (11) the password to the target server (A); and the target server (A) determines whether or not there is a correspondence between the password shared with the authentication server (B) and the password transmitted by the client terminal (C), and if said correspondence between passwords exists, the client terminal (C) is authenticated by the target server (A).
