Focused on a novel-proposed dynamic SDN framework, a game-theoretic model is presented to analyze its security performance. This model can represent several kinds of players\u2019 information, simulate approximate attack scenarios, and quantitatively estimate systems\u2019 reliability. And we explore several typical game instances defined by system\u2019s capability, players\u2019 objects, and strategies. Experimental results illustrate that the system\u2019s detection capability is not a decisive element to security enhancement as introduction of dynamism and redundancy into SDN can significantly improve security gain and compensate for its detection weakness. Moreover, we observe a range of common strategic actions across environmental conditions. And analysis reveals diverse defense mechanisms adopted in dynamic systems have different effect on security improvement. Besides, the existence of equilibrium in particular situations further proves the novel structure\u2019s feasibility, flexibility, and its persistent ability against long-term attacks.<\/jats:p>","DOI":"10.1155\/2018\/4123736","type":"journal-article","created":{"date-parts":[[2018,1,23]],"date-time":"2018-01-23T18:31:59Z","timestamp":1516732319000},"page":"1-10","source":"Crossref","is-referenced-by-count":6,"title":["Security Analysis of Dynamic SDN Architectures Based on Game Theory"],"prefix":"10.1155","volume":"2018","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6693-3135","authenticated-orcid":true,"given":"Chao","family":"Qi","sequence":"first","affiliation":[{"name":"National Digital Switching System Engineering & Technological R&D Center, Zhengzhou, Henan 450002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiangxing","family":"Wu","sequence":"additional","affiliation":[{"name":"National Digital Switching System Engineering & Technological R&D Center, Zhengzhou, Henan 450002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guozhen","family":"Cheng","sequence":"additional","affiliation":[{"name":"National Digital Switching System Engineering & Technological R&D Center, Zhengzhou, Henan 450002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianjian","family":"Ai","sequence":"additional","affiliation":[{"name":"National Digital Switching System Engineering & Technological R&D Center, Zhengzhou, Henan 450002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuo","family":"Zhao","sequence":"additional","affiliation":[{"name":"National Digital Switching System Engineering & Technological R&D Center, Zhengzhou, Henan 450002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1145\/1355734.1355746"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1109\/MCOM.2016.7378421"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1016\/j.comnet.2013.12.004"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1109\/TCC.2014.2355227"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1016\/j.comnet.2015.09.030"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1109\/TSE.2010.60"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1109\/TDSC.2011.34"},{"year":"2011","key":"18"},{"year":"2012","key":"19"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1145\/2480741.2480742"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1007\/s00145-012-9134-5"},{"key":"22","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-12601-2_10"},{"key":"26","doi-asserted-by":"publisher","DOI":"10.1049\/el.2016.2670"}],"container-title":["Security and Communication Networks"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/scn\/2018\/4123736.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/scn\/2018\/4123736.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/scn\/2018\/4123736.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2018,1,23]],"date-time":"2018-01-23T18:32:06Z","timestamp":1516732326000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/scn\/2018\/4123736\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018]]},"references-count":13,"alternative-id":["4123736","4123736"],"URL":"https:\/\/doi.org\/10.1155\/2018\/4123736","relation":{},"ISSN":["1939-0114","1939-0122"],"issn-type":[{"type":"print","value":"1939-0114"},{"type":"electronic","value":"1939-0122"}],"subject":[],"published":{"date-parts":[[2018]]}}}
