A method of effecting secure communication over a network begins by interfacing a hardware token with a computer host. The hardware token comprises security software and communication software stored thereon. The security software is stored in a memory of the hardware token. The computer host comprises a memory distinct from the hardware token memory. Tfte authenticity of the security software is determined on the hardware token. Upon successful validation of the authenticity of the security software on the hardware token, the authenticity of the communication software is determined by loading the security software from the hardware token memory into the computer host memory and executing the loaded security software from the computer host memory. After successful validation of the authenticity of the communication software, the computer host facilitates communication between the hardware token and a remote computer by executing the communication software from the computer host memory.

L'invention concerne un procédé pour effectuer une communication sécurisée sur un réseau qui commence par interfacer un jeton matériel à un ordinateur hôte. Le jeton matériel stocke un logiciel de sécurité et un logiciel de communication. Le logiciel de sécurité est stocké dans une mémoire du jeton matériel. L'ordinateur hôte comporte une mémoire distincte de la mémoire du jeton matériel. L'authenticité du logiciel de sécurité est déterminée sur le jeton matériel. A de la validation réussie de l'authenticité du logiciel de sécurité sur le jeton matériel, l'authenticité du logiciel de communication est déterminée par le chargement du logiciel de sécurité à partir de la mémoire du jeton matériel dans la mémoire de l'ordinateur hôte et par l'exécution du logiciel de sécurité chargé à partir de la mémoire de l'ordinateur hôte. Après la validation réussie de l'authenticité du logiciel de communication, l'ordinateur hôte facilite la communication entre le jeton matériel et un ordinateur distant en exécutant le logiciel de communication à partir de la mémoire de l'ordinateur hôte.
