Controlling access to BitTorrent content from mobile devices

By Péter Ekler and Zsolt Pszota


Abstract. BitTorrent technology is one of the most popular peer-to-peer solution. The technology ensures fast download speed without large servers. The download procedure needs special torrent les, which contains information about the requested content and the tracker address. The main tasks of the trackers are to control the tra c and help the participant to nd each other. The main goal of the protocol is not to share illegal content, it is because how it works. In order to stop the illegal tra c, we have to stop only the tracker, which is responsible for the copyrighted les. The BitTorrent technology based on a standard, but it has several extensions. One important question about the protocol is the defense of the shared content. How can we share something through BitTorrent if we do not want to make it available for everybody, only for a set of people? This function would be very useful, if we want to share private content to our friends, or if a company wants to share large les between the employees. Peer-to-peer le sharing technology has a play to role in the mobile world too. We took part of developing the SymTorrent application, which is a complete BitTorrent solution for mobile devices. Defending the shared content is also very important on mobile devices. We worked on a solution, how we can ensure that the shared content can be downloaded only by those, who we want to share it. We introduce some ideas and solutions about the topic, and a concrete method, with which the download can begin only after an authentication. We focus on SymTorrent application and solution for mobile devices, but we use the existing experiences in the PC world
