Integration of Peertrust in Peer-to-Peer networks

This workplan correspond to the Summer Semester Research program where students choose a topic and they should investigate on it. It is composed of 7 milestones where they have to learn about the state of the art in the topic selected achieving some goals and they have to present a final work at the end.

When a transaction between two entities needs to be done, both entities will need some information from the other party. While current approaches relies on the client/server approach where one of the two entities is registered on the other, Automated Trust Negotiation denotes the process where both parties ask and disclose information whenever it is needed according to their own policies.

The chosen topic consist on the integration of the Peertrust prototype into the Edutella Peer-to-Peer network. The current Peertrust framework behaves in a sense that each party involved in the negotiation might act as a client or as a server. This scenario already suggests a P2P architecture. The goal is to integrate Peertrust in Edutella (a schema-based Peer-2-Peer network developed in our laboratory). This integration will allow the distribution of a query into the network receiving an answer (if possible) from every peer.

The main goals of this work are:

• Introduction to Semantic Web & Security Technologies
• P2P networks
• Communication protocols
• Introduction to one of the most recent topics in security and access control: ATN
