It is thus essential to ensure security and preserve privacy. In this paper, we propose mix-context-based pseudonym changing privacy-preserving authentication (MPCPA). MPCPA introduces privacy protection through a mutual authentication mechanism to prevent attack-vehicles from sneaking into a VANET system. Moreover, it preserves the integrity of transmitted messages with an anonymous authentication mechanism. In addition, MPCPA adopts a mix-context-based pseudonym changing strategy to prevent vehicle tracking. A performance analysis demonstrates that MPCPA incurs low computational costs and offers a privacy-preserving scheme that is more secure than existing authentication schemes.<\/jats:p>","DOI":"10.1155\/2019\/3109238","type":"journal-article","created":{"date-parts":[[2019,6,2]],"date-time":"2019-06-02T19:33:10Z","timestamp":1559503990000},"page":"1-9","source":"Crossref","is-referenced-by-count":9,"title":["Mix-Context-Based Pseudonym Changing Privacy Preserving Authentication in VANETs"],"prefix":"10.1155","volume":"2019","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7592-5206","authenticated-orcid":true,"given":"Mengjia","family":"Zeng","sequence":"first","affiliation":[{"name":"School of Information Engineering, Huzhou University, Huzhou, Zhejiang 313000, China"},{"name":"Qiuzhen School of Huzhou Teachers College, Huzhou, Zhejiang 313000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2370-7573","authenticated-orcid":true,"given":"Huibin","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Information Engineering, Huzhou University, Huzhou, Zhejiang 313000, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1155\/2018\/1843083"},{"issue":"6","key":"2","first-page":"1582","volume":"35","year":"2015","journal-title":"System Engineering Theory and Practice"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1016\/j.vehcom.2017.02.001"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1109\/tvt.2015.2453160"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1109\/access.2017.2768499"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.3233\/jcs-2007-15103"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1109\/tvt.2011.2162864"},{"issue":"11","key":"9","first-page":"100","volume":"46","year":"2018","journal-title":"IEEE Communications"},{"issue":"7","key":"10","first-page":"1","volume":"3","year":"2017","journal-title":"IEEE Communications Surveys and Tutorials"},{"journal-title":"Proceedings of IEEE infocom","first-page":"816","year":"2008","key":"11"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1109\/tvt.2012.2186992"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1007\/s11277-014-2245-6"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1016\/j.future.2016.11.024"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1016\/j.future.2017.07.002"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1109\/tits.2016.2634623"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1109\/tdsc.2012.85"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1109\/tvt.2015.2487262"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1007\/s10586-012-0242-7"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1007\/s10586-017-0848-x"},{"key":"22","doi-asserted-by":"publisher","DOI":"10.1007\/s00145-004-0314-9"},{"key":"23","doi-asserted-by":"publisher","DOI":"10.1109\/tvt.2011.2162864"},{"key":"24","doi-asserted-by":"publisher","DOI":"10.1007\/s11276-014-0881-0"},{"key":"25","doi-asserted-by":"publisher","DOI":"10.1109\/jsac.2007.071007"},{"issue":"6","key":"26","first-page":"835","volume":"30","year":"2018","journal-title":"Journal of Chongqing University of Posts and Telecommunications (Natural Science Edition)"}],"container-title":["Mobile Information Systems"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2019\/3109238.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2019\/3109238.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/misy\/2019\/3109238.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,6,2]],"date-time":"2019-06-02T19:33:16Z","timestamp":1559503996000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/misy\/2019\/3109238\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,6,2]]},"references-count":24,"alternative-id":["3109238","3109238"],"URL":"https:\/\/doi.org\/10.1155\/2019\/3109238","relation":{},"ISSN":["1574-017X","1875-905X"],"issn-type":[{"type":"print","value":"1574-017X"},{"type":"electronic","value":"1875-905X"}],"subject":[],"published":{"date-parts":[[2019,6,2]]}}}
