This Authenticated Encryption with Associated Data algorithm is very fast and extremely small in terms of hardware implementation. In this work, we study a differential cryptanalytic attack against TinyJambu. It is a deeper analysis than previous works found in the literature as well as it also obtains better differential probabilities than those of other studies. More precisely, we develop a differential forgery attack with probability 2\u201365.7845, what is much better than 2\u221280 obtained by the own designers and better than 2\u201370.12 the best probability obtained by other authors. In brief, we have reduced the margin of security against a forgery attack for this proposal of lightweight cryptosystem. Later, NIST allows to tweak TinyJambu by increasing the number of rounds from 384 up to 640. This round increment means a greater security margin than before. For this updated version of TinyJambu, we analyse some properties of the new algorithm that allow TinyJambu to be considered for particular IoT applications as well.<\/jats:p>","DOI":"10.1093\/jigpal\/jzaf015","type":"journal-article","created":{"date-parts":[[2025,6,1]],"date-time":"2025-06-01T07:34:28Z","timestamp":1748763268000},"source":"Crossref","is-referenced-by-count":0,"title":["The lightweight cryptosystem TinyJambu: security and applications in IoT environments"],"prefix":"10.1093","volume":"34","author":[{"given":"Amparo","family":"F\u00faster-Sabater","sequence":"first","affiliation":[{"name":"Institute of Physical and Information Technologies, Department TIC, CSIC , 144 Serrano, 28006 Madrid ,","place":["Spain"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mar\u00eda Eugenia","family":"Pazo-Robles","sequence":"additional","affiliation":[{"name":"Institute of Physical and Information Technologies, Department TIC, CSIC , 144 Serrano, 28006 Madrid ,","place":["Spain"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2026,1,28]]},"reference":[{"key":"2026012811024163700_ref1","author":"National Institute of Standards and Technology","year":"2019"},{"key":"2026012811024163700_ref2"},{"key":"2026012811024163700_ref3","author":"Wu","year":"2020"},{"key":"2026012811024163700_ref4","doi-asserted-by":"crossref","first-page":"152","DOI":"10.46586\/tosc.v2020.i3.152-174","article-title":"On the security margin of TinyJAMBU with refined differential and linear cryptanalysis","volume":"2020","author":"Saha","year":"2020","journal-title":"IACR Transactions on Symmetric Cryptology"},{"key":"2026012811024163700_ref5"},{"key":"2026012811024163700_ref6","first-page":"57","volume-title":"Inscrypt 2011, LNCS","author":"Mouha","year":"2012"},{"key":"2026012811024163700_ref7","doi-asserted-by":"publisher","first-page":"5317","DOI":"10.1038\/s41598-022-09004-3","volume-title":"Cube attacks on round-reduced TiniJAMBU","author":"Teng","year":"2022"},{"key":"2026012811024163700_ref8","volume-title":"The Marsaglia Random Number CDROM including the Diehard Battery of Tests of Randomness","author":"Marsaglia","year":"2010"},{"key":"2026012811024163700_ref9"},{"key":"2026012811024163700_ref10","volume-title":"SCA Evaluation and Benchmarking of Finalists in the NIST Standardization Process","author":"Mohajerani"},{"key":"2026012811024163700_ref11","volume-title":"Performance Evaluation of NIST LWC Finalists on AVR ATmega and ARM Cortex-M3 Microcontrollers","author":"Watanabe"},{"key":"2026012811024163700_ref12","first-page":"205","article-title":"Software evaluation for second round candidates in NIST lightweight cryptography","volume":"31","author":"Hira","year":"2023","journal-title":"J Inf Process"},{"key":"2026012811024163700_ref13","author":"MQTT"},{"key":"2026012811024163700_ref14","volume-title":"Analysis of Practical Application of Lightweight Cryptographic Algorithm ASCON","author":"Avery"}],"container-title":["Logic Journal of the IGPL"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/academic.oup.com\/jigpal\/article-pdf\/34\/1\/jzaf015\/66611772\/jzaf015.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"https:\/\/academic.oup.com\/jigpal\/article-pdf\/34\/1\/jzaf015\/66611772\/jzaf015.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,1,28]],"date-time":"2026-01-28T16:04:49Z","timestamp":1769616289000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/jigpal\/article\/doi\/10.1093\/jigpal\/jzaf015\/8443239"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,1,27]]},"references-count":14,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2026,1,27]]}},"URL":"https:\/\/doi.org\/10.1093\/jigpal\/jzaf015","relation":{},"ISSN":["1367-0751","1368-9894"],"issn-type":[{"value":"1367-0751","type":"print"},{"value":"1368-9894","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2026,2]]},"published":{"date-parts":[[2026,1,27]]},"article-number":"jzaf015"}}
