Trustworthy Negotiation

Project Summary

In typical ad-hoc networks, nodes range from laptops to small units such as sensors. The mobility and changing availability of nodes fundamentally alter the requirements for trust establishment in these environments. Automated trust negotiation (ATN) is a method that lets two strangers safely conduct interactions in order to create a level of mutual trust. In this method, credentials signed by certificate authorities are exchanged through an iterative disclosure process that allows each credential to have a disclosure policy. We achieved the goal we set out in our project plan of implementing our previously developed theoretical concepts in a prototype. The prototype, which is called OC (for “Open Collaboration”), is a Java program for peer-to-peer collaboration and resource sharing. OC is a generic tool for automated trust negotiation that can be used as a testbed for implementing our theoretical models, testing and comparing their performance, and supporting application development in order to later test real-world applications.
