MULTI-CLOUD ENCRYPTED SEARCH VERIFICATION
International Research Journal of Modernization in Engineering Technology and Science · 2024
This paper addresses the limitations of existing single cloud-based searchable encryption schemes by proposing a paper approach for keyword-based search over encrypted data in a multi-cloud server model.While multi-cloud setups offer enhanced data availability and security, direct migration from single-cloud schemes incurs higher storage and search costs without distinct security benefits.To address query integrity challenges in multi-cloud environments, we introduce an iterative encryption method ensuring file privacy against clouding servers.Leveraging Bloom filters, we create tree indexes for each cloud server enabling secure distributed keyword searches.Our fast verification algorithm embeds content and index details into file IDs to verify query integrity.Rigorous analysis and experiments confirm the security and efficiency of our proposed scheme.
