The proposed multisensor fusion framework provides secure state estimates by using ideas from interactive multiple models (IMM) combined with a novel fuzzy\u2010based attack detection\/isolation mechanism. The IMM filter is used to adjust the system\u2019s uncertainty adaptively via model probabilities by using a hybrid state model consisting of two behaviour modes, one corresponding to the ideal scenario and one associated with the attack behaviour mode. The state chi\u2010square test is then incorporated through the proposed fuzzy\u2010based fusion framework to detect and isolate potential data injection attacks. In other words, the validation probability of each sensor is calculated based on the value of the chi\u2010square test. Finally, by incorporation of the validation probability of each sensor, the weights of its associated subsystem are computed. To be concrete, an integrated navigation system is simulated with three types of attacks ranging from a constant bias attack to a non\u2010Gaussian stochastic attack to evaluate the proposed attack detection and isolation fusion framework.<\/jats:p>","DOI":"10.1155\/2018\/1240149","type":"journal-article","created":{"date-parts":[[2018,2,11]],"date-time":"2018-02-11T23:30:39Z","timestamp":1518391839000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Attack Detection\/Isolation via a Secure Multisensor Fusion Framework for Cyberphysical Systems"],"prefix":"10.1155","volume":"2018","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1972-7923","authenticated-orcid":false,"given":"Arash","family":"Mohammadi","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chun","family":"Yang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2653-1956","authenticated-orcid":false,"given":"Qing-wei","family":"Chen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2018,2,11]]},"reference":[{"key":"e_1_2_8_1_2","doi-asserted-by":"publisher","DOI":"10.1109\/TAC.2013.2266831"},{"key":"e_1_2_8_2_2","doi-asserted-by":"publisher","DOI":"10.1109\/TII.2012.2226594"},{"key":"e_1_2_8_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/TSG.2014.2387381"},{"key":"e_1_2_8_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/JPROC.2012.2235131"},{"key":"e_1_2_8_5_2","doi-asserted-by":"publisher","DOI":"10.1109\/JSYST.2014.2322503"},{"key":"e_1_2_8_6_2","doi-asserted-by":"publisher","DOI":"10.1109\/TII.2015.2469260"},{"key":"e_1_2_8_7_2","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2014.2385670"},{"key":"e_1_2_8_8_2","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2014.2386281"},{"key":"e_1_2_8_9_2","doi-asserted-by":"publisher","DOI":"10.1109\/TAC.2014.2350231"},{"key":"e_1_2_8_10_2","doi-asserted-by":"publisher","DOI":"10.1109\/TAC.2014.2303233"},{"key":"e_1_2_8_11_2","doi-asserted-by":"publisher","DOI":"10.1109\/TIE.2012.2185011"},{"key":"e_1_2_8_12_2","doi-asserted-by":"publisher","DOI":"10.1109\/TSG.2015.2495133"},{"key":"e_1_2_8_13_2","doi-asserted-by":"crossref","unstructured":"WeiJ.
