In 1973, Feistel used a key selected S-box mechanism in his early block cipher designs, whose idea is to let each S-box have two different states and use a key bit to select which of the two states is to be used in an encryption or decryption operation. However, this key selected S-box mechanism has not got much attention in modern block cipher design with the DES block cipher published in 1977. In this paper, we revisit Feistel\u2019s key selected S-box mechanism, give a generalised version of Feistel\u2019s key selected S-box mechanism, compare it with existing close notions, and design the LBC example cipher to demonstrate that the generalised key selected S-box mechanism can be advantageous over the ordinary S-box mechanism in modern block cipher design for improving security and\/or performance without intensifying computational effort and space in some application environments.<\/jats:p>","DOI":"10.1155\/2020\/1457419","type":"journal-article","created":{"date-parts":[[2020,5,26]],"date-time":"2020-05-26T23:30:34Z","timestamp":1590535834000},"page":"1-26","source":"Crossref","is-referenced-by-count":4,"title":["A Key Selected S-Box Mechanism and Its Investigation in Modern Block Cipher Design"],"prefix":"10.1155","volume":"2020","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4622-0722","authenticated-orcid":true,"given":"Jiqiang","family":"Lu","sequence":"first","affiliation":[{"name":"Beihang University, Beijing, China"}]},{"given":"Hwajung","family":"Seo","sequence":"additional","affiliation":[{"name":"Hansung University, Seoul, Republic of Korea"}]}],"member":"311","reference":[{"year":"1977","key":"1"},{"year":"2001","key":"2"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1038\/scientificamerican0573-15"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1109\/proc.1975.10005"},{"issue":"9","key":"5","first-page":"125","volume":"28","year":"2007","journal-title":"Journal of Communications"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1007\/bf00630563"},{"year":"2010","key":"11"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1080\/0161-118491858746"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1007\/s00145-001-0009-4"},{"year":"2010","key":"44","first-page":"800"},{"year":"2012","key":"45","first-page":"800"}],"container-title":["Security and Communication Networks"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/scn\/2020\/1457419.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/scn\/2020\/1457419.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/scn\/2020\/1457419.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,5,26]],"date-time":"2020-05-26T23:30:38Z","timestamp":1590535838000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/scn\/2020\/1457419\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,5,26]]},"references-count":11,"alternative-id":["1457419","1457419"],"URL":"https:\/\/doi.org\/10.1155\/2020\/1457419","relation":{},"ISSN":["1939-0114","1939-0122"],"issn-type":[{"type":"print","value":"1939-0114"},{"type":"electronic","value":"1939-0122"}],"subject":[],"published":{"date-parts":[[2020,5,26]]}}}
