CA 2254936

A secured system is provided for accessing application services running on a remote server (12) from a client station (15). The system includes at least one client station (15), each having low-level graphical interface and file logic stored therein and at least one controller, such as a digital signal processor. The controller controls the graphical interface and the file logic. The file logic includes a file system capable of storing data corresponding to the application programs. Further, the system includes at least one remote application server (12), each server having high-level application logic for running corresponding application programs stored locally or remotely. In addition, a low-level interface connects each client and server. In this system, the cost of manufacturing such clients (15) are far less expensive but far more robust than conventional general purpose computers. Further, the server application programs need not be written specific to or be dependent on any specific operating system platform.

Cette invention se rapporte à un système sûr d'accès à des services d'application s'exécutant sur un serveur éloigné (12), à partir d'une station client (15). Ledit système comporte au moins une station client (15), équipée d'une interface graphique de bas niveau et d'une logique de fichiers, et au moins un organe de commande, tel qu'une unité de traitement des signaux. Ledit organe de commande gère l'interface graphique et la logique de fichiers. Ladite logique de fichiers comprend un système de fichiers capable de stocker les données correspondant aux programmes d'application. En outre, ledit système inclut au moins un serveur (12) d'application éloigné, doté d'une logique d'application de haut niveau conçue pour exécuter les programmes d'application correspondants, stockés localement ou à distance. Une interface de bas niveau relie en outre chaque client au serveur. Dans ce système, le coût de fabrication de ces stations clients (15) est beaucoup moins important que celui de fabrication d'ordinateurs universels traditionnels, et les stations clients sont beaucoup plus robustes que lesdits ordinateurs universels. En outre, il n'est pas nécessaire que les programmes d'application du serveur soient écrits spécifiquement pour une plate-forme de système d'exploitation particulière ou soient dépendants d'une telle plate-forme.
