Therefore, in terms of flexibility, data deduplication should be combined with data access control techniques. In this paper, we propose an authorized deduplication scheme using CP-ABE to solve this problem. The proposed scheme provides client-side deduplication while providing confidentiality through client-side encryption to prevent exposure of users\u2019 sensitive data on untrusted cloud servers. Also, unlike existing convergent encryption schemes, it provides authorized convergent encryption by using CP-ABE to allow only authorized users to access critical data. The proposed authorized deduplication scheme provides an adequate trade-off between storage space efficiency and security in cloud environment and is very suitable for the hybrid cloud model considering both the data security and the storage efficiency in a business environment.<\/jats:p>","DOI":"10.1155\/2019\/7840917","type":"journal-article","created":{"date-parts":[[2019,5,15]],"date-time":"2019-05-15T19:31:55Z","timestamp":1557948715000},"page":"1-11","source":"Crossref","is-referenced-by-count":8,"title":["Authorized Client-Side Deduplication Using CP-ABE in Cloud Storage"],"prefix":"10.1155","volume":"2019","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3840-2254","authenticated-orcid":true,"given":"Taek-Young","family":"Youn","sequence":"first","affiliation":[{"name":"Electronics and Telecommunications Research Institute (ETRI), Daejeon 34129, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1721-5350","authenticated-orcid":true,"given":"Nam-Su","family":"Jho","sequence":"additional","affiliation":[{"name":"Electronics and Telecommunications Research Institute (ETRI), Daejeon 34129, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0466-8254","authenticated-orcid":true,"given":"Kyung Hyune","family":"Rhee","sequence":"additional","affiliation":[{"name":"Department of IT Convergence and Application Eng., Pukyong National University, Busan 48513, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7048-582X","authenticated-orcid":true,"given":"Sang Uk","family":"Shin","sequence":"additional","affiliation":[{"name":"Department of IT Convergence and Application Eng., Pukyong National University, Busan 48513, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1109\/TBDATA.2017.2656120"},{"issue":"1","key":"2","first-page":"4","volume":"8","year":"2017","journal-title":"Journal of Wireless Mobile Networks, Ubiquitous Computing, and Dependable Applications (JoWUA)"},{"issue":"6","key":"4","doi-asserted-by":"crossref","first-page":"40","DOI":"10.1109\/MSP.2010.187","volume":"8","year":"2010","journal-title":"IEEE Security & Privacy"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1016\/j.pmcj.2015.03.002"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1109\/TPDS.2014.2318320"},{"issue":"4","key":"9","first-page":"1229","volume":"19","year":"2018","journal-title":"Journal of Internet Technology"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2018.2836328"},{"journal-title":"National Institute of Standards and Technology (NIST)","year":"2013","key":"15"},{"year":"2001","key":"16"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2017.2669940"},{"key":"18","first-page":"259","volume-title":"Computationally efficient ciphertext-policy attribute-based encryption with constant-size ciphertexts","volume":"8782","year":"2014"},{"issue":"4","key":"19","first-page":"37","volume":"8","year":"2018","journal-title":"Journal of Internet Services and Information Security (JISIS"},{"journal-title":"Draft NIST Special Publication 800-131A Revision 2, National Institute of Standards and Technology (NIST)","year":"2018","key":"20"}],"container-title":["Wireless Communications and Mobile Computing"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/wcmc\/2019\/7840917.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/wcmc\/2019\/7840917.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/wcmc\/2019\/7840917.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,5,15]],"date-time":"2019-05-15T19:31:58Z","timestamp":1557948718000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/wcmc\/2019\/7840917\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,5,15]]},"references-count":13,"alternative-id":["7840917","7840917"],"URL":"https:\/\/doi.org\/10.1155\/2019\/7840917","relation":{},"ISSN":["1530-8669","1530-8677"],"issn-type":[{"type":"print","value":"1530-8669"},{"type":"electronic","value":"1530-8677"}],"subject":[],"published":{"date-parts":[[2019,5,15]]}}}
