Second, Levin will present \u0022Alibi Routing,\u0022 a peer-to-peer system that provides proof that a user\u0027s packets could not have gone through a region of the world the user forbids. Finally, he will describe some of his ongoing and future efforts, including securing the Web\u0027s public key infrastructure.\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EBio:\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EDave Levin is a research scientist and co-chair of the Computer Science Undergraduate Honors program at the University of Maryland. He previously worked in the Social Computing Group at Hewlett-Packard Labs after getting his Ph.D. from the University of Maryland in 2010. Dave has received a best paper award at NSDI, and a best reviewer award from ACM SIGCOMM. His work lies at the intersection of networking, security, and economics.\u0026nbsp;\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Visiting Lecture from Dave Levin, research scientist at the University of Maryland"}],"uid":"30267","created_gmt":"2016-03-14 17:09:16","changed_gmt":"2017-04-13 21:16:19","author":"Devin Young","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2016-04-07T12:00:00-04:00","event_time_end":"2016-04-07T13:30:00-04:00","event_time_end_last":"2016-04-07T13:30:00-04:00","gmt_time_start":"2016-04-07 16:00:00","gmt_time_end":"2016-04-07 17:30:00","gmt_time_end_last":"2016-04-07 17:30:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"hg_media":{"506261":{"id":"506261","type":"image","title":"Dave Levin","body":null,"created":"1456765200","gmt_created":"2016-02-29 17:00:00","changed":"1475895268","gmt_changed":"2016-10-08 02:54:28","alt":"Dave Levin","file":{"fid":"205924","name":"davelevin.png","image_path":"\/sites\/default\/files\/images\/davelevin_0.png","image_full_path":"http:\/\/www.tlwarc.hg.gatech.edu\/\/sites\/default\/files\/images\/davelevin_0.png","mime":"image\/png","size":263770,"path_740":"http:\/\/www.tlwarc.hg.gatech.edu\/sites\/default\/files\/styles\/740xx_scale\/public\/images\/davelevin_0.png?itok=Xd-IHM1C"}}},"media_ids":["506261"],"groups":[{"id":"47223","name":"College of Computing"},{"id":"50875","name":"School of Computer Science"}],"categories":[],"keywords":[{"id":"1051","name":"Computer Science"},{"id":"168467","name":"dave levin"},{"id":"2437","name":"lecture"},{"id":"166941","name":"School of Computer Science"},{"id":"166940","name":"SCS"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1795","name":"Seminar\/Lecture\/Colloquium"}],"invited_audience":[{"id":"78751","name":"Undergraduate students"},{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"id":"174045","name":"Graduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cp\u003E\u003Cstrong\u003EElizabeth Ndongi\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003E\u003Ca href=\u0022mailto:Ndongi@cc.gatech.edu\u0022\u003ENdongi@cc.gatech.edu\u003C\/a\u003E\u003C\/p\u003E","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
