An ordinary difference equation (a map) can be used in encryption\u2013decryption algorithms. In particular, the Arnold\u2019s cat and the sine-Gordon linear maps can be used in cryptographic algorithms for encoding digital images. In this article, a two-dimensional linear mKdV map derived from an ordinary difference mKdV equation will be used in a cryptographic encoding algorithm. The proposed encoding algorithm will be compared with those generated using sine-Gordon and Arnold\u2019s cat maps via the correlations between adjacent pixels in the encrypted image and the uniformity of the pixel distribution. Note that the mKdV map is derived from the partial discrete mKdV equation with Consistency Around the Cube (CAC) properties, whereas the sine-Gordon map is derived from the partial discrete sine-Gordon equation, which does not have CAC properties.<\/jats:p>","DOI":"10.3390\/a14040124","type":"journal-article","created":{"date-parts":[[2021,4,16]],"date-time":"2021-04-16T10:20:11Z","timestamp":1618568411000},"page":"124","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["A Two-Dimensional mKdV Linear Map and Its Application in Digital Image Cryptography"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5566-4264","authenticated-orcid":false,"given":"La","family":"Zakaria","sequence":"first","affiliation":[{"name":"Department of Mathematics, Universitas Lampung, Bandar Lampung 35145, Indonesia"}]},{"given":"Endah","family":"Yuliani","sequence":"additional","affiliation":[{"name":"Department of Mathematics, Universitas Lampung, Bandar Lampung 35145, Indonesia"}]},{"given":"Asmiati","family":"Asmiati","sequence":"additional","affiliation":[{"name":"Department of Mathematics, Universitas Lampung, Bandar Lampung 35145, Indonesia"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,16]]},"reference":[{"key":"ref_1","first-page":"10","article-title":"A public key cryptosystem and a signature scheme based on discrete logarithms","volume":"31","author":"Elgamal","year":"1985","journal-title":"Lect.
