To date, such schemes have unfortunately been limited mainly to collision-resistant hash functions and public-key encryption.\u003C\/p\u003E\n\u003Cp class=\u0022style15 style14 style15 style14\u0022\u003EThis talk will describe how to securely exploit innate \u0022trapdoors\u0022 in lattices. The cryptographic applications include new kinds of trapdoor functions, simple \u0022hash-and-sign\u0022 digital signature schemes, and identity-based encryption -- all based on standard worst-case lattice assumptions. The talk will be self-contained, and no prior knowledge of lattices will be assumed.\u003C\/p\u003E\n\u003Cp class=\u0022style15 style14 style15 style14\u0022\u003EJoint work with Craig Gentry and Vinod Vaikuntanathan.\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":"","uid":"27154","created_gmt":"2010-02-11 15:57:53","changed_gmt":"2016-10-08 01:50:09","author":"Louise Russo","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2008-03-11T16:00:00-04:00","event_time_end":"2008-03-11T17:00:00-04:00","event_time_end_last":"2008-03-11T17:00:00-04:00","gmt_time_start":"2008-03-11 20:00:00","gmt_time_end":"2008-03-11 21:00:00","gmt_time_end_last":"2008-03-11 21:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"47223","name":"College of Computing"}],"categories":[],"keywords":[],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"allyana ziolko","format":"limited_html"}],"email":[],"slides":[],"orientation":[],"userdata":""}}}
