Comparing with proxy signatures, multi-proxy signatures can effectively prevent that some of proxy signers abuse signing rights. Also, with the rapid development of identity-based cryptography, identity-based multi-proxy signature (IBMPS) schemes have been proposed. Comparing with proxy signature based on public key cryptography, IBMPS can simplify key management and be used for more applications. Presently, many identity-based multi-proxy signature schemes have been proposed, but most of them are constructed in the random oracle model. Also, the existing security model for identity-based multi-proxy signature is not enough complete according to the Boldyreva et al.\u2019s work. In this paper, we present a framework for IBMPS on n + 1 users ( n is the number of proxy signers participating in signing), and show a detailed security model for IBMPS. Under our framework, we present an identity-based multi-proxy signature scheme in the standard model. Comparing with other identity-based multi-proxy signature schemes, the proposed scheme has more complete security. <\/jats:p>","DOI":"10.3233\/fi-2017-1464","type":"journal-article","created":{"date-parts":[[2017,3,6]],"date-time":"2017-03-06T12:14:55Z","timestamp":1488802495000},"page":"179-210","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":14,"title":["Identity-Based Multi-Proxy Signature Scheme in the Standard Model"],"prefix":"10.1177","volume":"150","author":[{"given":"Ke","family":"Gu","sequence":"first","affiliation":[{"name":"School of Computer and Communication Engineering, Changsha University of Science and Technology, Changsha, 410114, China."}]},{"given":"Weijia","family":"Jia","sequence":"additional","affiliation":[{"name":"School of Information Science and Engineering, Central South University, Changsha, 410083, China"}]},{"given":"Jianming","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Computer and Communication Engineering, Changsha University of Science and Technology, Changsha, 410114, China"}]}],"member":"179","published-online":{"date-parts":[[2017,3,3]]},"container-title":["Fundamenta Informaticae"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/FI-2017-1464","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.3233\/FI-2017-1464","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,7,1]],"date-time":"2025-07-01T10:50:00Z","timestamp":1751367000000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.3233\/FI-2017-1464"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,3,3]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2017,3,3]]}},"alternative-id":["10.3233\/FI-2017-1464"],"URL":"https:\/\/doi.org\/10.3233\/fi-2017-1464","relation":{},"ISSN":["0169-2968","1875-8681"],"issn-type":[{"value":"0169-2968","type":"print"},{"value":"1875-8681","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,3,3]]}}}
