The new scheme has some advantages over the available schemes: the private keys size shrinks as the identity depth increases and the signature size is a constant as it consists of three group elements. Furthermore, under the h-CDH assumption, our scheme is provably secure in the standard model. This assumption is more natural than many of the hardness assumptions recently introduced to HIBS in the standard model.<\/jats:p>","DOI":"10.3233\/fi-2009-0013","type":"journal-article","created":{"date-parts":[[2019,12,2]],"date-time":"2019-12-02T22:22:41Z","timestamp":1575325361000},"page":"191-201","source":"Crossref","is-referenced-by-count":10,"title":["New Construction of Short Hierarchical ID-Based Signature in the \t\t\t Standard Model"],"prefix":"10.1177","volume":"90","author":[{"given":"Leyou","family":"Zhang","sequence":"first","affiliation":[{"name":"Department of Mathematical Science, Xidian University,\r\t\t\t XI'AN, ShaanXi Province 710071, China.\r\t\t\t leyouzhang77@yahoo.com.cn"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yupu","family":"Hu","sequence":"additional","affiliation":[{"name":"Key Laboratory of Computer Networks and Information\r\t\t\t Security, Xidian University, XI'AN, ShaanXi Province 710071,\r\t\t\t China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qing","family":"Wu","sequence":"additional","affiliation":[{"name":"Department of Mathematical Science, Xidian University,\r\t\t\t XI'AN, ShaanXi Province 710071, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2009,1,1]]},"container-title":["Fundamenta Informaticae"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/FI-2009-0013","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/FI-2009-0013","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T06:37:16Z","timestamp":1777444636000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.3233\/FI-2009-0013"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,1]]},"references-count":0,"journal-issue":{"issue":"1-2","published-print":{"date-parts":[[2009,1]]}},"alternative-id":["10.3233\/FI-2009-0013"],"URL":"https:\/\/doi.org\/10.3233\/fi-2009-0013","relation":{},"ISSN":["0169-2968","1875-8681"],"issn-type":[{"value":"0169-2968","type":"print"},{"value":"1875-8681","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,1]]}}}
