Most of these ciphers are designed with Addition\u2013Rotation\u2013Xor (ARX)-based structure for the resource-constrained environment because ARX operations can be implemented efficiently, especially in software. However, if the word size of a block cipher is smaller than the register size of the target device, it may process inefficiently in the aspect of memory usage. In this article, we present a fast implementation method for ARX-based block ciphers, named two-way operation. Moreover, also we applied SPARX-64\/128 and CHAM-64\/128 and estimated the performance in terms of execution time (cycles per byte) on a 32-bit Advanced RISC Machines processor. As a result, we achieved a large amount of improvement in execution time. The cycles of round function and key schedule are reduced by 53.31% and 31.51% for SPARX-64\/128 and 41.22% and 19.40% for CHAM-64\/128. <\/jats:p>","DOI":"10.1177\/1550147719874180","type":"journal-article","created":{"date-parts":[[2019,9,11]],"date-time":"2019-09-11T09:32:58Z","timestamp":1568194378000},"page":"155014771987418","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":9,"title":["Fast implementations of ARX-based lightweight block ciphers (SPARX, CHAM) on 32-bit processor"],"prefix":"10.1177","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8130-5011","authenticated-orcid":false,"given":"Byoungjin","family":"Seok","sequence":"first","affiliation":[{"name":"Department of Computer Science and Engineering, Seoul National University of Science &amp;
