This dissertation develops techniques and systems that empower\u003C\/p\u003E\r\n\r\n\u003Cp\u003Eusers to evade such intentions of adversaries. Our work builds from\u003C\/p\u003E\r\n\r\n\u003Cp\u003Ethe observation to leverage randomness in physical nature of the world\u003C\/p\u003E\r\n\r\n\u003Cp\u003Eeverywhere, specifically using technologies such as wireless and\u003C\/p\u003E\r\n\r\n\u003Cp\u003Epower-lines networks in urban settings. This thesis is divided into\u003C\/p\u003E\r\n\r\n\u003Cp\u003Etwo parts. First part, we develop Denali, which allows deniable\u003C\/p\u003E\r\n\r\n\u003Cp\u003Ecommunication in wireless 802.11 networks. Denali achieves this by\u003C\/p\u003E\r\n\r\n\u003Cp\u003Eleveraging the weakness of wireless networks which has packet\u003C\/p\u003E\r\n\r\n\u003Cp\u003Ecorruption due to its ubiquitous nature of being broadcast\u003C\/p\u003E\r\n\r\n\u003Cp\u003Emedium. This is the first such system which uses off-the-shelf\u003C\/p\u003E\r\n\r\n\u003Cp\u003Ecommodity hardware to users.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EIn the second part, we explore a different network primarily used for\u003C\/p\u003E\r\n\r\n\u003Cp\u003Epowering devices in building infrastructure -- power-line network. We\u003C\/p\u003E\r\n\r\n\u003Cp\u003Ebuild Power-line Whisperer, a physical layer covert communication\u003C\/p\u003E\r\n\r\n\u003Cp\u003Echannel. Power-line Whisperer is the first of its kind of system to\u003C\/p\u003E\r\n\r\n\u003Cp\u003Emake it easier for people to to do deniable communication on power-line\u003C\/p\u003E\r\n\r\n\u003Cp\u003Enetworks. Both these systems allow the users to do point-to-point\u003C\/p\u003E\r\n\r\n\u003Cp\u003Ecommunication and defend against powerful adversaries who might be\u003C\/p\u003E\r\n\r\n\u003Cp\u003Einterested in snooping on the message exchange for malicious reasons.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Near-Field Deniable Communication"}],"uid":"27707","created_gmt":"2017-05-15 13:21:14","changed_gmt":"2017-05-19 14:52:32","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2017-05-24T12:00:00-04:00","event_time_end":"2017-05-24T14:00:00-04:00","event_time_end_last":"2017-05-24T14:00:00-04:00","gmt_time_start":"2017-05-24 16:00:00","gmt_time_end":"2017-05-24 18:00:00","gmt_time_end_last":"2017-05-24 18:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
