Garcia-Alfaro, J. Herrera-Joancomart\u00ed and J. Meli\u00e0-Segu\u00ed published in Sensors 2015, 15, 6217\u20136220. Peinado et al. cryptanalyzed the pseudorandom number generator proposed by Meli\u00e0-Segu\u00ed et al., describing two possible attacks. Later, Garcia-Alfaro claimed that one of this attack did not hold in practice because the assumptions made by Peinado et al. were not correct. This letter reviews those remarks, showing that J3Gen is anyway flawed and that, without further information, the interpretation made by Peinado et al. seems to be correct.<\/jats:p>","DOI":"10.3390\/s150511988","type":"journal-article","created":{"date-parts":[[2015,5,26]],"date-time":"2015-05-26T04:16:36Z","timestamp":1432613796000},"page":"11988-11992","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Revision of J3Gen and Validity of the Attacks by Peinado et al."],"prefix":"10.3390","volume":"15","author":[{"given":"Alberto","family":"Peinado","sequence":"first","affiliation":[{"name":"Escuela T\u00e9cnica Superior de Ingenier\u00eda de Telecomunicaci\u00f3n, Universidad de M\u00e1laga, M\u00e1laga 29071, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2795-312X","authenticated-orcid":false,"given":"Jorge","family":"Munilla","sequence":"additional","affiliation":[{"name":"Escuela T\u00e9cnica Superior de Ingenier\u00eda de Telecomunicaci\u00f3n, Universidad de M\u00e1laga, M\u00e1laga 29071, 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, Consejo Superior de Investigaciones Cient\u00edficas, Madrid 28006, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2015,5,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"6217","DOI":"10.3390\/s150306217","article-title":"Remarks on Peinado et al.\u2019s Analysis of J3Gen","volume":"15","year":"2015","journal-title":"Sensors"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"6500","DOI":"10.3390\/s140406500","article-title":"EPCGen2 Pseudorandom Number Generators: Analysis of J3Gen","volume":"14","author":"Peinado","year":"2014","journal-title":"Sensors"},{"key":"ref_3","doi-asserted-by":"crossref","unstructured":"Meli\u00e0-Segu\u00ed, J., Garcia-Alfaro, J., and Herrera-Joancomart\u00ed, J.
