A Peertrust - Prolog translator

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 generation of a parser between two different languages.The peertrust system uses a language based on prolog. Although languages based on logic are used all over the world in order to describe policies to protect resources, still many users are not familiarized to them. That is why an easier and more user-friendly language which users might use instead of was provided. The goal here is to provide a translation from and to its real representation in Prolog.

The main goals of this work are:

• Introduction to Semantic Web & Security Technologies
• Grammars and Language processing
• Parser generators
• Introduction to one of the most recent topics in security and access control: ATN
