In addition to the traditional credentials, CLAS profiles RTL values of clients and uses them to defend against password compromise. The key challenges are (i) to prevent RTL manipulation, (ii) to alleviate network instabilities, and (iii) to address mobile clients. CLAS addresses the first challenge by introducing a novel network architecture, which makes it extremely difficult for attackers to simulate legitimate RTL values. The second challenge is addressed by outlier removal and multiple temporal profiling, while the last challenge is addressed by augmenting CLAS with out-of-band-channels or other authentication schemes. CLAS restricts login to profiled locations while demanding additional information for nonprofiled ones, which highly reduces the attack surface even when the legitimate credentials are compromised. Additionally, unlike many state-of-the-art authentication mechanisms, CLAS is resilient to phishing, pharming, man-in-the-middle, and social engineering attacks. Furthermore, CLAS is transparent to users and incurs negligible overhead. The experimental results show that CLAS can achieve very low false positive and false negative rates.<\/jats:p>","DOI":"10.1155\/2017\/4286903","type":"journal-article","created":{"date-parts":[[2017,6,12]],"date-time":"2017-06-12T21:03:00Z","timestamp":1497301380000},"page":"1-20","source":"Crossref","is-referenced-by-count":3,"title":["CLAS: A Novel Communications Latency Based Authentication Scheme"],"prefix":"10.1155","volume":"2017","author":[{"ORCID":"http:\/\/orcid.org\/0000-0002-3880-5125","authenticated-orcid":true,"given":"Zuochao","family":"Dou","sequence":"first","affiliation":[{"name":"Department of Electrical and Computer Engineering, New Jersey Institute of Technology, Newark, NJ, USA"}]},{"ORCID":"http:\/\/orcid.org\/0000-0002-7660-9512","authenticated-orcid":true,"given":"Issa","family":"Khalil","sequence":"additional","affiliation":[{"name":"Qatar Computing Research Institute, Hamad Bin Khalifa University, Doha, Qatar"}]},{"given":"Abdallah","family":"Khreishah","sequence":"additional","affiliation":[{"name":"Department of Electrical and Computer Engineering, New Jersey Institute of Technology, Newark, NJ, USA"}]}],"member":"98","reference":[{"key":"40","doi-asserted-by":"publisher","DOI":"10.1109\/MSP.2011.1"},{"key":"43","doi-asserted-by":"publisher","DOI":"10.1109\/TIFS.2011.2169958"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-39884-1_27"},{"key":"26","doi-asserted-by":"publisher","DOI":"10.1016\/j.cose.2010.12.001"},{"key":"25","year":"1999","journal-title":"In Workshop on IDNM"},{"key":"17","year":"2014","journal-title":"Communications Surveys and Tutorials"},{"key":"27","doi-asserted-by":"publisher","DOI":"10.1109\/TSC.2014.2300499"},{"key":"32","doi-asserted-by":"publisher","DOI":"10.1109\/TDSC.2010.74"},{"key":"39","doi-asserted-by":"publisher","DOI":"10.1016\/j.adhoc.2007.11.015"},{"key":"24","year":"2015"},{"key":"29","doi-asserted-by":"publisher","DOI":"10.1007\/springerreference"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1016\/j.cose.2014.03.005"},{"key":"34","doi-asserted-by":"publisher","DOI":"10.1109\/90.731185"},{"key":"22","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-14527-8_1"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1109\/JSYST.2017.2669908"},{"key":"31","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-23829-6_8"},{"key":"37","doi-asserted-by":"publisher","DOI":"10.1016\/S0167-739X(99)00059-X"},{"key":"36","doi-asserted-by":"publisher","DOI":"10.1016\/j.jesp.2013.03.013"}],"container-title":["Security and Communication Networks"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/scn\/2017\/4286903.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/scn\/2017\/4286903.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/scn\/2017\/4286903.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,12]],"date-time":"2017-06-12T21:03:00Z","timestamp":1497301380000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/scn\/2017\/4286903\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017]]},"references-count":18,"alternative-id":["4286903","4286903"],"URL":"https:\/\/doi.org\/10.1155\/2017\/4286903","relation":{},"ISSN":["1939-0114","1939-0122"],"issn-type":[{"value":"1939-0114","type":"print"},{"value":"1939-0122","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017]]}}}
