Abstract
A device, such as a chip card, is connected to a host platform that is linked to a packet network such as the Internet. The device detects security policy designation parameters in packets leaving and entering the platform and processes the packets according to stored security policies designated by the designation parameters detected. The security information linked to a user can therefore be moved from one platform to another and it is not processed by the platform. Security policies are managed by a server with which the device can initiate a communication when no security policy corresponding to the policy designation parameters detected in a packet is recognized, so that the server can assist the device in negotiating a security policy.
