Abstract

<abstract abstract-type="main" id="spe2226-abs-0001"> <title>Summary</title> <p id="spe2226-para-0001">This paper describes <sc>TRUSTPACK</sc>, a decentralized trust management framework that provides trust management as a generic service. <sc>TRUSTPACK</sc> is unique in that it does not provide a central service. Instead, it is run by many autonomous services. This design enables <sc>TRUSTPACK</sc> to alleviate privacy concerns, as well as potentially provide better personalization and scalability when compared with current centralized solutions. A major component of <sc>TRUSTPACK</sc> is a generic decentralized graph query processing framework called <sc>GRAPHPACK</sc>, which was also developed as part of this work. <sc>GRAPHPACK</sc> consists of a decentralized graph processing language as well as an execution engine, as elaborated in this paper. The paper also presents several examples and a case study showing how <sc>TRUSTPACK</sc> can be used to handle various trust management scenarios, as well as its incorporation in an existing third party P2P file sharing application. Prototypes of <sc>TRUSTPACK</sc> and <sc>GRAPHPACK</sc> are available as open source projects at <ext-link ext-link-type="uri" xlink:href="http://code.google.com/p/trustpack/" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">http://code.google.com/p/trustpack/</ext-link> and <ext-link ext-link-type="uri" xlink:href="http://code.google.com/p/graphpack/" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">http://code.google.com/p/graphpack/</ext-link>, respectively.
