To solve those problems, the\n   interactive protocol among participants is introduced, an extirpation-based\n   key derivation algorithm (EKDA) is designed to manage the keys, a double\n   hashed and weighted Bloom Filter (DWBF) is proposed to retrieve the encrypted\n   keywords, which are combined with lazy revocation, multi-tree structure,\n   asymmetric and symmetric encryptions, which form a privacypreserving,\n   efficient and secure framework for cloud storage. The experiment and security\n   analysis show that EKDA can reduce the communication and storage overheads\n   efficiently, DWBF supports ciphertext retrieval and can reduce communication,\n   storage and computation overhead as well, and the proposed framework is\n   privacy preserving while supporting data access efficiently.<\/jats:p>","DOI":"10.2298\/csis100327029r","type":"journal-article","created":{"date-parts":[[2011,7,7]],"date-time":"2011-07-07T11:10:09Z","timestamp":1310037009000},"page":"801-819","source":"Crossref","is-referenced-by-count":15,"title":["Study of privacy-preserving framework for cloud storage"],"prefix":"10.2298","volume":"8","author":[{"given":"Huang","family":"Ruwei","sequence":"first","affiliation":[{"name":"Department of Electronics and Information Engineering, Xi\u2019an Jiaotong University, Xi\u2019an, China + School of Computer, Electronics and Information, GuangXi University, NanNing, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gui","family":"Xiaolin","sequence":"additional","affiliation":[{"name":"Department of Electronics and Information Engineering, Xi\u2019an Jiaotong University, Xi\u2019an, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu","family":"Si","sequence":"additional","affiliation":[{"name":"Department of Electronics and Information Engineering, Xi\u2019an Jiaotong University, Xi\u2019an, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhuang","family":"Wei","sequence":"additional","affiliation":[{"name":"Department of Electronics and Information Engineering, Xi\u2019an Jiaotong University, Xi\u2019an, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1078","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1145\/362686.362692"}],"container-title":["Computer Science and Information Systems"],"original-title":[],"language":"en","deposited":{"date-parts":[[2023,5,29]],"date-time":"2023-05-29T08:30:17Z","timestamp":1685349017000},"score":1,"resource":{"primary":{"URL":"https:\/\/doiserbia.nb.rs\/Article.aspx?ID=1820-02141100029R"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011]]},"references-count":1,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2011]]}},"URL":"https:\/\/doi.org\/10.2298\/csis100327029r","relation":{},"ISSN":["1820-0214","2406-1018"],"issn-type":[{"value":"1820-0214","type":"print"},{"value":"2406-1018","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011]]}}}
