Storing, managing, and processing large quantities of unstructured data generated by IoT devices remain a huge challenge to cloud service providers (CSP). To reduce the storage overhead, CSPs implement deduplication algorithms on the cloud storage servers. It identifies and eliminates the redundant data blocks. However, implementing post-progress deduplication schemes does not address the bandwidth issues. Also, existing convergent key-based deduplication schemes are highly vulnerable to confirmation of file attacks (CFA) and can leak confidential information. To overcome these issues, FogDedupe, a fog-centric deduplication framework, is proposed. It performs source-level deduplication on the fog nodes to reduce the bandwidth usage and post-progress deduplication to improve the cloud storage efficiency. To perform source-level deduplication, a distributed index table is created and maintained in the fog nodes, and post-progress deduplication is performed using a multi-key homomorphic encryption technique. To evaluate the proposed FogDedupe framework, a testbed environment is created using the open-source Eucalyptus v.4.2.0 software and fog project v1.5.9 package. The proposed scheme tightens the security against CFA attacks and improves the storage overhead by 27% and reduces the deduplication latency by 12%.<\/jats:p>","DOI":"10.1155\/2022\/6759875","type":"journal-article","created":{"date-parts":[[2022,8,26]],"date-time":"2022-08-26T00:35:09Z","timestamp":1661474109000},"page":"1-16","source":"Crossref","is-referenced-by-count":11,"title":["FogDedupe: A Fog-Centric Deduplication Approach Using Multi-Key Homomorphic Encryption Technique"],"prefix":"10.1155","volume":"2022","author":[{"given":"Mohamed Sirajudeen","family":"Yoosuf","sequence":"first","affiliation":[{"name":"School of Computer Science and Engineering, VIT-AP University Amaravati, Andhra Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.","family":"Muralidharan","sequence":"additional","affiliation":[{"name":"School of Computing Technology, SRM University, Chennai, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4931-724X","authenticated-orcid":true,"given":"S.","family":"Shitharth","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Engineering, Kebri Dehar, Kebri Debar University, Ethiopia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohammed","family":"Alghamdi","sequence":"additional","affiliation":[{"name":"Department of Information Systems, College of Computer Science, King Khalid University, Abha, Saudi Arabia"},{"name":"Department of Information and Technology Systems, College of Computer Science and Engineering, University of Jeddah, Jeddah, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7066-2945","authenticated-orcid":true,"given":"Mohammed","family":"Maray","sequence":"additional","affiliation":[{"name":"Department of Information Systems, College of Computer Science, King Khalid University, Abha, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8680-7080","authenticated-orcid":true,"given":"Osama Bassam J.","family":"Rabie","sequence":"additional","affiliation":[{"name":"Department of Information Systems, Faculty of Computing and Information Technology, King Abdulaziz University, Jeddah, Saudi Arabia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2021.3073203"},{"article-title":"Whitepaper","year":"2025","author":"IDC Data Age","key":"2"},{"key":"3","article-title":"Newspaper Article"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1109\/TKDE.2016.2580139"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1007\/978-981-10-3373-5_53"},{"issue":"1","key":"6","first-page":"824","article-title":"An optimized data duplication strategy for cloud computing: Dedup with ABE and bloom filters","volume":"13","author":"N.
