However, existing lattice\u2010based AB\u2010CPREs suffer from some drawbacks such as large parameters and weak passive securities.

The security of our proposed AB\u2010CPREs is based on standard LWE assumptions. We further introduce the directly revocable AB\u2010CPREs, a primitive that enables a delegator to authorize and revoke his delegation of decryption rights dynamically and offers more flexible access control on externally stored encrypted data. Definition and security model of single\u2010hop directly revocable AB\u2010CPREs are given, and the first detailed construction of single\u2010hop directly revocable AB\u2010CPREs based on standard LWE assumptions is also proposed.\n                  <\/jats:p>","DOI":"10.1049\/2024\/4333883","type":"journal-article","created":{"date-parts":[[2024,9,26]],"date-time":"2024-09-26T11:42:33Z","timestamp":1727350953000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Improved AB\u2010CPREs with Revocability and HRA Security under LWE"],"prefix":"10.1049","volume":"2024","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9274-8195","authenticated-orcid":false,"given":"Yang","family":"Wang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9221-4230","authenticated-orcid":false,"given":"Mingqiang","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"265","published-online":{"date-parts":[[2024,9,26]]},"reference":[{"key":"e_1_2_10_1_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jisa.2020.102543"},{"key":"e_1_2_10_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-030-88428-4_8"},{"key":"e_1_2_10_3_2","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-030-02744-5_7"},{"key":"e_1_2_10_4_2","first-page":"206","volume-title":"Provable Security","author":"Yang Y.","year":"2014"},{"key":"e_1_2_10_5_2","doi-asserted-by":"crossref","unstructured":"ZhaoJ.
