The generalized self-shrinking generator, a sequence generator based on irregular decimation, produces a family of sequences with good cryptographic properties. In this work, we display a detailed analysis on the randomness of the sequences resulting from the concatenation of elements of this family. We apply the most important batteries of statistical and graphical tests providing powerful results and a new method to construct sequences with good cryptographic properties.<\/jats:p>","DOI":"10.1093\/jigpal\/jzac008","type":"journal-article","created":{"date-parts":[[2022,1,25]],"date-time":"2022-01-25T12:19:36Z","timestamp":1643113176000},"page":"993-1004","source":"Crossref","is-referenced-by-count":1,"title":["Randomness study of the concatenation of generalized sequences"],"prefix":"10.1093","volume":"30","author":[{"given":"Sara D","family":"Cardell","sequence":"first","affiliation":[{"name":"Centro de Matem\u00e1tica , Computa\u00e7\u00e3o e Cogni\u00e7\u00e3o, UFABC, 09210-580 Santo Andr\u00e9, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amalia B","family":"Or\u00fae","sequence":"additional","affiliation":[{"name":"Facultad de Ciencias y Tecnolog\u00eda, Universidad Isabel I , 09003 Burgos, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ver\u00f3nica","family":"Requena","sequence":"additional","affiliation":[{"name":"Departamento de Matem\u00e1ticas, Universidad de Alicante , 03690 Alicante, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amparo","family":"F\u00faster-Sabater","sequence":"additional","affiliation":[{"name":"Instituto de Tecnolog\u00edas F\u00edsicas y de la Informaci\u00f3n , CSIC, 28006 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2022,2,18]]},"reference":[{"key":"2023011113045218200_ref1","doi-asserted-by":"crossref","first-page":"1749","DOI":"10.1016\/j.chaos.2004.07.006","article-title":"Cryptanalyzing an improved security modulated chaotic encryption scheme using ciphertext absolute value","volume":"23","author":"Alvarez","year":"2005","journal-title":"Chaos, Solitons & Fractals"},{"key":"2023011113045218200_ref2","volume-title":"Fractals Everywhere","author":"Barnsley","year":"1988"},{"key":"2023011113045218200_ref3","article-title":"Crypt x package documentation","volume-title":"Tech.
