Abstract : Whereas security is a key notion in the world of distributed applications, its numerous concepts are a difficult step to overcome when constructing such applications. Current middlewares provide all major security-related technologies. However developers still have to select the more accurate one and handle all its underlying processes which is particurally difficult with dynamic, grid-enabled applications. To facilitate the use of security concepts in such application, this thesis presents a decentralised security model which takes care of security requirements expressed by all actors (resource providers, administrators, users) involved in a computation. The model is implemented outside the application source code. Its configuration is read from external policy files allowing the adaptation of the application's security according to its deployment. It has been conceived to handle specific behaviors which could happen during a distributed application life-cycle (use of newly discovered resources, remote object creation). Moreover, the implentation within the ProActive library has valided the approach and had demonstrated its advantages. Indeed, thanks to its transparency, it has been seamlessly integrated with the other features of the library (migration, group communications, components, peer-topeer). Benchmarks have consolidated the validity of the approach.
