Searchable encryption (SE) is recognized as a crucial cryptographic primitive for data owners to retrieve data in this context. However, most current SE schemes suffer from low keyword search accuracy and an inability to verify search results. Additionally, encrypted data should be shared with specific data users without compromising their privacy. Therefore, this article introduces a novel fuzzy keyword\u2010enabled ranked searchable ciphertext\u2010policy attribute\u2010based encryption (FKRSCPABE) scheme to address these challenges. First, we combine ciphertext\u2010policy attribute\u2010based encryption (CP\u2010ABE) and public\u2010key encryption with keyword search (PEKS) to realize fine\u2010grained access control and efficiently search outsourced encrypted data for data owners. Second, since the document almost certainly contains typographical errors, we implement fuzzy keyword search to ensure meaningful and accurate results. Additionally, we employ probabilistic trapdoors to resist distinguishability attacks. Furthermore, we rank documents using weighted regional scores to improve search accuracy. As a result, our scheme achieves IND\u2010CCA security by using the classic Canetti transformation. In brief, our scheme is able to achieve fuzzy keyword search and better ranking of search results, while also ensuring data security.<\/jats:p>","DOI":"10.1002\/cpe.70479","type":"journal-article","created":{"date-parts":[[2025,12,12]],"date-time":"2025-12-12T06:07:11Z","timestamp":1765519631000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Novel Searchable Attribute\u2010Based Encryption Scheme Supporting Fuzzy Keywords Ranking for the Cloud Environment"],"prefix":"10.1002","volume":"38","author":[{"given":"Gangqi","family":"Shu","sequence":"first","affiliation":[{"name":"School of Computer Science and Technology, Zhejiang Key Laboratory of Big Data and Future E\u2010Commerce Technology Zhejiang Gongshang University  Hangzhou P.R.
