By its very nature, mining effective features in data plays a crucial role in data-driven deep learning. In this paper, in addition to considering the integrity of the information from the training data of the ciphertext pair, domain knowledge about the structure of differential cryptanalysis is also considered into the training process of deep learning to improve the performance. Meanwhile, taking the performance of the differential-neural distinguisher of Simon 32\/64 as an entry point, we investigate the impact of input difference on the performance of the hybrid distinguishers to choose the proper input difference. Eventually, we improve the accuracy of the neural distinguishers of Simon 32\/64, Simon 64\/128, Simeck 32\/64 and Simeck 64\/128. We also obtain related-key differential-based neural distinguishers on round-reduced versions of Simon 32\/64, Simon 64\/128, Simeck 32\/64 and Simeck 64\/128 for the first time.<\/jats:p>","DOI":"10.1093\/comjnl\/bxac195","type":"journal-article","created":{"date-parts":[[2023,1,23]],"date-time":"2023-01-23T14:52:43Z","timestamp":1674485563000},"page":"537-547","source":"Crossref","is-referenced-by-count":29,"title":["Improved (Related-Key) Differential-Based Neural Distinguishers for SIMON and SIMECK Block Ciphers"],"prefix":"10.1093","volume":"67","author":[{"given":"Jinyu","family":"Lu","sequence":"first","affiliation":[{"name":"College of Sciences, National University of Defense Technology , Deya Road, Hunan, Changsha 410073 , China"},{"name":"Hunan Engineering Research Center of Commercial Cryptography Theory and Technology Innovation,\u00a0Deya Road , Hunan, Changsha 410073 , China"},{"name":"State Key Laboratory of Cryptology , PO Box 5159, Beijing 100878 , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guoqiang","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Sciences, National University of Defense Technology , Deya Road, Hunan, Changsha 410073 , China"},{"name":"Hunan Engineering Research Center of Commercial Cryptography Theory and Technology Innovation,\u00a0Deya Road , Hunan, Changsha 410073 , China"},{"name":"State Key Laboratory of Information Security (Institute of Information Engineering, Chinese Academy of Sciences , West\u00a0Chang'an Street,\u00a0Beijing 100093 , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bing","family":"Sun","sequence":"additional","affiliation":[{"name":"College of Sciences, National University of Defense Technology , Deya Road, Hunan, Changsha 410073 , China"},{"name":"Hunan Engineering Research Center of Commercial Cryptography Theory and Technology Innovation,\u00a0Deya Road , Hunan, Changsha 410073 , China"},{"name":"State Key Laboratory of Cryptology , PO Box 5159, Beijing 100878 , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chao","family":"Li","sequence":"additional","affiliation":[{"name":"College of Sciences, National University of Defense Technology , Deya Road, Hunan, Changsha 410073 , China"},{"name":"Hunan Engineering Research Center of Commercial Cryptography Theory and Technology Innovation,\u00a0Deya Road , Hunan, Changsha 410073 , China"},{"name":"State Key Laboratory of Cryptology , PO Box 5159, Beijing 100878 , China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Li","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Systems Engineering, National University of Defense Technology , Deya Road, Hunan, Changsha 410073 , China"},{"name":"Center for Machine Vision and Signal Analysis, University of Oulu , Pentti Kaiteran katu 1,\u00a0Oulu 90570 , Finland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2023,1,22]]},"reference":[{"key":"2024021913325832800_ref1","doi-asserted-by":"crossref","first-page":"3","DOI":"10.1007\/BF00630563","article-title":"Differential cryptanalysis of des-like cryptosystems","volume":"4","author":"Biham","journal-title":"J.
