Infrastructure de gestion de la confiance sur internet

Abstract : Trust establishment is an important problem which often arises everyday. We need to assess the trust in someone or something before making decisions on their actions. It is also a very important problem for Internet applications where participants of a system are virtual entities. The trust establishment is a key factor for e-commerce applications and services which involve interactions with unknown users.The objective of this thesis is to build an infrastructure for trust management which allows each participant to express his own security policy. The security policy is a way for the participant to define his own access control to his own resources and services. The infrastructure provides a trust negotiation mechanism that allows two participants to establish a mutual trust between them for interactions.The important point of our proposal of an infrastructure for trust management is that we use all available information such as credentials (signed certificates), reputations, recommendations or risk information about the peer to make decisions on trust. All these factors are expressed in the security policy by using our proposed policy language.
