In the diffusion stage, two rounds of diffusion are adopted and the rules of DNA encoding (DNA decoding) are dynamically changed according to the pixel value of the plaintext image, that is, the rules of DNA encoding (DNA decoding) used to encrypt different images are different, which makes the algorithm can resist chosen-plaintext attack. The encryption (decryption) key is only the initial value of the chaotic system, which overcomes the difficulty of key management in the \u201cone time pad\u201d encryption system. The experimental results and security analysis show that the algorithm has some advantages of large key space, no obvious statistical characteristics of ciphertext, sensitivity to plaintext and key and able to resist differential attacks and chosen plaintext attack. It has good application prospects.<\/jats:p>","DOI":"10.3390\/e22070772","type":"journal-article","created":{"date-parts":[[2020,7,15]],"date-time":"2020-07-15T10:35:18Z","timestamp":1594809318000},"page":"772","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":73,"title":["Secure Image Encryption Algorithm Based on Hyperchaos and Dynamic DNA Coding"],"prefix":"10.3390","volume":"22","author":[{"given":"Shuqin","family":"Zhu","sequence":"first","affiliation":[{"name":"School of Computer Science, Liaocheng University, Liaocheng 252059, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9662-0532","authenticated-orcid":false,"given":"Congxu","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Computer Science and Engineering, Central South University, Changsha 410083, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,7,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Li, T., Shi, J., Li, X., Wu, J., and Pan, F.
