CA 2335082

A data processing system implements a security protocol based on processing data in packets. The data processing system comprises packet processing means (301) for storing filter code (304) and processing data packets according to stored filter code, and policy managing means (305) for generating filter code and communicating generated filter code to the packet processing means (301). The packet processing means (301) is arranged to examine, whether the stored filter code is applicable for processing a certain packet. If the stored filter code is not applicable for the processing of a packet, the packet is communicated to the policy managing means (305), which generates filter code applicable for the processing of the packet and communicates the generated filter code to the packet processing means (301).

Selon cette invention, un système de traitement de données met en oeuvre un protocole de sécurité sur la base du traitement de données par paquets. Le système de traitement de données comprend un système de traitement de paquets (301) servant à stocker le code de filtrage (304) et à traiter les paquets de données conformément au code de filtrage stocké, ainsi qu'un système (305) de gestion de politiques qui génère le code de filtrage et communique le code de filtrage généré au système de traitement de paquets (301). Le système de traitement de paquets (301) est conçu pour examiner les cas où le code de filtrage stocké s'applique au traitement d'un paquet déterminé. Si le code de filtrage stocké ne s'applique pas au traitement du paquet, le paquet est communiqué au système (305) de gestion de la politique qui génère le code de filtrage applicable au traitement du paquet et communique le code de filtrage généré au système de traitement de paquets (301).
