Recently, there have been many formal security analyses for the most important low-latency protocols: the just-released TLS 1.3 and a relatively recent secure transport protocol QUIC from Google that is available in the Chrome browser. But their security, when layered with their underlying transport protocols, cannot be easily compared. The first work I will present in the proposal tries to solve this problem.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EAfter establishing a secure channel, a user often logs in to a server by typing in a password. But if the user\u0026rsquo;s terminal has been fully compromised, the password will be leaked and his future communications cannot be protected. This problem is addressed by the second work I will present, which constructs the first user authentication and key exchange protocols that can tolerate strong corruptions on the client-side.\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003EThe above protocol handled strong corruptions but still requires the user to type in some one-time password on the terminal, which is not very efficient. Recently, the Fast Identity Online (FIDO) Alliance has been working on a password-free user authentication standard called FIDO2. I will finally present our ongoing work on FIDO2 security analysis.\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":"Towards Secure Communication and Authentication: Provable Security Analysis and New Constructions "}],"uid":"27707","created_gmt":"2019-04-19 13:22:12","changed_gmt":"2019-04-19 13:22:12","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2019-04-24T14:30:00-04:00","event_time_end":"2019-04-24T16:30:00-04:00","event_time_end_last":"2019-04-24T16:30:00-04:00","gmt_time_start":"2019-04-24 18:30:00","gmt_time_end":"2019-04-24 20:30:00","gmt_time_end_last":"2019-04-24 20:30:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"102851","name":"Phd proposal"}],"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":"174045","name":"Graduate students"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
