A system consistent with the present invention enables a program in a distributed system to determine whether downloaded code is trustworthy before using the downloaded code to communicate with other programs or services in the distributed system. A client that downloads proxy code from a service can verify that both the service and the downloaded code are trustworthy before using the code to communicate with the service. "Trustworthy" code is code the client knows will enforce the client's security constraints in communicating with the service, e.g., mutual authentication, confidentiality, and integrity.
L'invention concerne un procédé permettant à un programme, dans un système réparti, de déterminer si un code téléchargé est fiable avant utilisation de ce code téléchargé pour communiquer avec d'autres programmes ou services, dans le système réparti. Un client, qui télécharge un code mandataire à partir d'un service, peut vérifier si à la fois le service et le code téléchargé sont fiables avant d'utiliser le code pour communiquer avec le service. Le code <=fiable>= est celui connu par le client pour répondre aux exigences de sécurité du client dans la communication avec le service, par exemple, l'authentification mutuelle, la confidentialité et l'intégrité.
