In this paper, we address the problem of privacy and liability in VANETs. We propose a scheme that provides location privacy by utilizing a variant of ring signature. It allows a vehicle to form a ring arbitrarily with nearby vehicles and sign its messages anonymously, so that it can hide itself in the surrounding vehicles. When solving a dispute, the real signer will be responsible for what it has signed as the anonymity is revocable by the authority. <\/jats:p>","DOI":"10.1155\/2014\/473151","type":"journal-article","created":{"date-parts":[[2014,3,25]],"date-time":"2014-03-25T04:01:21Z","timestamp":1395720081000},"page":"473151","update-policy":"http:\/\/dx.doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["A Collaboratively Hidden Location Privacy Scheme for VANETs"],"prefix":"10.1177","volume":"10","author":[{"given":"Ying","family":"Mei","sequence":"first","affiliation":[{"name":"School of Computer Science and Technology, Huazhong University of Science and Technology, Wuhan 430074, China"},{"name":"College of Educational Information and Technology, Hubei Normal University, Huangshi 435002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guozhou","family":"Jiang","sequence":"additional","affiliation":[{"name":"College of Educational Information and Technology, Hubei Normal University, Huangshi 435002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Computer, Central China Normal University, Wuhan 430079, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yongquan","family":"Cui","sequence":"additional","affiliation":[{"name":"School of Computer Science and Technology, Huazhong University of Science and Technology, Wuhan 430074, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2014,3,24]]},"reference":[{"key":"B1-2014-473151","doi-asserted-by":"publisher","DOI":"10.3233\/JCS-2007-15103"},{"key":"B2-2014-473151","doi-asserted-by":"publisher","DOI":"10.1109\/LCN.2007.143"},{"key":"B3-2014-473151","doi-asserted-by":"publisher","DOI":"10.1109\/TVT.2007.906878"},{"key":"B4-2014-473151","volume-title":"WIT 2005","author":"Matthias G.","year":"2007"},{"key":"B5-2014-473151","doi-asserted-by":"publisher","DOI":"10.1145\/1287748.1287752"},{"key":"B6-2014-473151","doi-asserted-by":"publisher","DOI":"10.1109\/ITST.2007.4295890"},{"key":"B9-2014-473151","doi-asserted-by":"publisher","DOI":"10.1109\/WCNC.2005.1424677"},{"key":"B10-2014-473151","doi-asserted-by":"publisher","DOI":"10.1109\/VNC.2009.5416380"},{"key":"B11-2014-473151","volume-title":"Proceedings of the 1st International Workshop on Wireless Networking For Intelligent Transportation Systems (Win-ITS '07)","author":"Freudiger J."},{"key":"B12-2014-473151","doi-asserted-by":"publisher","DOI":"10.1109\/PCCC.2011.6108111"},{"key":"B7-2014-473151","doi-asserted-by":"publisher","DOI":"10.1016\/j.compeleceng.2011.11.009"},{"key":"B8-2014-473151","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-642-22619-9_8"},{"key":"B13-2014-473151","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-540-30576-7_18"},{"key":"B14-2014-473151","doi-asserted-by":"publisher","DOI":"10.1007\/3-540-45682-1_32"},{"key":"B15-2014-473151","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-540-71677-8_12"},{"key":"B16-2014-473151","doi-asserted-by":"publisher","DOI":"10.1007\/11761679_21"},{"key":"B17-2014-473151","doi-asserted-by":"publisher","DOI":"10.1109\/TVT.2011.2162864"},{"key":"B18-2014-473151","doi-asserted-by":"publisher","DOI":"10.1016\/j.jnca.2013.02.003"}],"container-title":["International Journal of Distributed Sensor Networks"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1155\/2014\/473151","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journals.sagepub.com\/doi\/full-xml\/10.1155\/2014\/473151","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/journals.sagepub.com\/doi\/pdf\/10.1155\/2014\/473151","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,5,16]],"date-time":"2021-05-16T16:26:14Z","timestamp":1621182374000},"score":1,"resource":{"primary":{"URL":"http:\/\/journals.sagepub.com\/doi\/10.1155\/2014\/473151"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,3,1]]},"references-count":18,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2014,3,1]]}},"alternative-id":["10.1155\/2014\/473151"],"URL":"https:\/\/doi.org\/10.1155\/2014\/473151","relation":{},"ISSN":["1550-1477","1550-1477"],"issn-type":[{"value":"1550-1477","type":"print"},{"value":"1550-1477","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014,3,1]]}}}
