It is challenging to build a secure identity-based signcryption scheme that can be proven secure in a standard model. In this paper, we address the issue and propose a novel construction of identity-based signcryption which enjoys IND-CCA security and existential unforgeability without resorting to the random oracle model. Comparisons demonstrate that the new scheme achieves stronger security, better performance efficiency and shorter system parameters.<\/jats:p>","DOI":"10.3390\/info8020058","type":"journal-article","created":{"date-parts":[[2017,5,23]],"date-time":"2017-05-23T01:47:33Z","timestamp":1495504053000},"page":"58","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["A Novel Identity-Based Signcryption Scheme in the Standard Model"],"prefix":"10.3390","volume":"8","author":[{"given":"Yueying","family":"Huang","sequence":"first","affiliation":[{"name":"Basic Education College of Lingnan Normal University, 524300 Zhanjiang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junjie","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Information Engineering, Lingnan Normal University, 524048 Zhanjiang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2017,5,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Shamir, A.
