ATTRIBUTE-BASED ENCRYPTION APPROACH FOR STORAGE, SHARING AND RETRIEVAL OF ENCRYPTED DATA IN THE CLOUD

ATTRIBUTE-BASED ENCRYPTION APPROACH FOR STORAGE, SHARING AND RETRIEVAL OF ENCRYPTED DATA IN THE CLOUD 1Mrs. K. KAVYA, 2K. POOJITHA, 3B. INDHU, 4K. VINAY KUMAR 03 05 Cloud computing has become a dominant platformfor storing and managing large volumes of data dueto its scalability costeffectiveness andaccessibility However outsourcing sensitive datato thirdparty cloud service providers introducessignificant security and privacy concerns Thisproject proposes an efficient and secure approachfor cloud data storage sharing and retrieval usingAttributeBased Encryption ABE The systemensures data confidentiality by allowing onlyauthorized users with matching attributes to accessencrypted information Unlike traditionalencryption methods which rely heavily oncomplex key management the proposed systemembeds access policies directly into the ciphertextenabling finegrained access control Additionallythe integration of AttributeBased SearchableEncryption ABSE allows users to perform securesearches over encrypted data without revealingsensitive information to the cloud provider Thesystem utilizes a hybrid encryption modelcombining symmetric encryption for dataefficiency and ABE for secure key distributionFurthermore advanced cryptographic techniquessuch as bilinear pairings and TypeIII curvesenhance system security while maintainingcomputational efficiency The proposed modelimproves scalability reduces communicationoverhead and supports dynamic user managementExperimental considerations demonstrate that thesystem is practical for realworld applications andensures high security with minimal performancetradeoffs Overall this approach provides areliable solution for protecting sensitive cloud datawhile enabling efficient sharing and retrieval
