Aiming at these problems, this paper proposes a new color image encryption algorithm based on the hyperchaotic system and applying \u201ctransforming-scrambling-diffusion\u201d model. Before scrambling, in accordance with the plaintext itself attributes, the number of iterations was calculated, all the pixel values of color image were transformed into gray code iteratively, and then the chaotic sequence was generated from the four-dimensional hyperchaotic system. Pixel matrix after gray code transformation was converted to one-dimensional matrix. The chaotic sequence was sorted and the one-dimensional matrix was changed positions correspondingly to complete the whole domain scrambling. And then, bit-operation was executed for image diffusion. The ciphertext can be obtained by matrix transformation. The key sensitivity, histogram, information entropy, correlation, and other evaluation indexes were calculated and analyzed through the simulation experiment. Compared with other algorithms, it can be proved that the encryption algorithm has the strong antiattack ability.<\/jats:p>","DOI":"10.1155\/2019\/8132547","type":"journal-article","created":{"date-parts":[[2019,6,27]],"date-time":"2019-06-27T19:32:08Z","timestamp":1561663928000},"page":"1-8","source":"Crossref","is-referenced-by-count":16,"title":["A Hyperchaotic Color Image Encryption Algorithm and Security Analysis"],"prefix":"10.1155","volume":"2019","author":[{"given":"Chenghai","family":"Li","sequence":"first","affiliation":[{"name":"Air and Missile Defense College, Air Force Engineering University, Xi\u2019an, Shanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0421-5917","authenticated-orcid":true,"given":"Fangzheng","family":"Zhao","sequence":"additional","affiliation":[{"name":"Graduate School, Air Force Engineering University, Xi\u2019an, Shanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chen","family":"Liu","sequence":"additional","affiliation":[{"name":"Air and Missile Defense College, Air Force Engineering University, Xi\u2019an, Shanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lei","family":"Lei","sequence":"additional","affiliation":[{"name":"Air and Missile Defense College, Air Force Engineering University, Xi\u2019an, Shanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9278-4812","authenticated-orcid":true,"given":"Jie","family":"Zhang","sequence":"additional","affiliation":[{"name":"Graduate School, Air Force Engineering University, Xi\u2019an, Shanxi, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"2","doi-asserted-by":"publisher","DOI":"10.1007\/978-81-322-1771-8_32"},{"issue":"6","key":"4","first-page":"1770","volume":"32","year":"2015","journal-title":"Application Research of Computers"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1016\/j.eij.2015.10.001"},{"key":"6","volume":"7","year":"2018","journal-title":"Computer Engineering and Design"},{"issue":"4","key":"8","first-page":"134","volume":"43","year":"2016","journal-title":"Computer Science"},{"key":"9","volume":"2","year":"2018","journal-title":"Chinese Journal of Computational Mechanics"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1007\/bf03322557"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1142\/S0218127418500840"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1016\/j.optlaseng.2016.10.012"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1016\/j.ins.2014.02.131"},{"key":"15","year":"2019","journal-title":"Digital Image Processing Using SCILAB"},{"key":"16","volume":"1019","year":"2018","journal-title":"Journal of Physics Conference Series"},{"key":"17","volume":"6","year":"2018","journal-title":"Computer & Digital Engineering"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1016\/j.optcom.2014.10.042"},{"issue":"2","key":"19","first-page":"131","volume":"32","year":"2014","journal-title":"Journal of Jilin University (Information Science Edition)"},{"issue":"01","key":"22","first-page":"121","volume":"01","year":"2011","journal-title":"International Journal of Engineering & Computer Science"},{"key":"23","doi-asserted-by":"publisher","DOI":"10.1007\/s10278-007-9044-5"},{"issue":"4","key":"24","first-page":"117","volume":"35","year":"2012","journal-title":"Journal of Changchun University of Science and Technology (Natural Science Edition)"},{"issue":"1","key":"25","first-page":"121","volume":"40","year":"2009","journal-title":"Journal of Central South University"},{"key":"26","first-page":"31","year":"April 2011","journal-title":"IEEE Journal on Selected Areas in Communications"}],"container-title":["Security and Communication Networks"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/scn\/2019\/8132547.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/scn\/2019\/8132547.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/scn\/2019\/8132547.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,9,22]],"date-time":"2019-09-22T06:44:58Z","timestamp":1569134698000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/scn\/2019\/8132547\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,6,27]]},"references-count":20,"alternative-id":["8132547","8132547"],"URL":"https:\/\/doi.org\/10.1155\/2019\/8132547","relation":{},"ISSN":["1939-0114","1939-0122"],"issn-type":[{"value":"1939-0114","type":"print"},{"value":"1939-0122","type":"electronic"}],"subject":[],"published":{"date-parts":[[2019,6,27]]}}}
