An Efficient RSA Based Data Integrity Schema in Secured Cloud Storage

摘要

This study aim is to address the problem of outsourcing data. Cloud computing is the delivery of computing as a service rather than a product, whereby shared resources, software and information are provided to computers and other devices as a utility over a network. The imperative feature of cloud services is that the user data are frequently processed remotely in unidentified machines that users do not own or operate. Due to this reason, the data owner loss their original data and it becomes an important obstruction to the extensive implementation of cloud services. This study introduces the term data accountability based encryption and users can substitute to a Third-Party Auditor (TPA) for the verification of data integrity problem. This study proposes the security of the outsourced data in cloud by generating keys for each cloud user attribute with Attribute Based Encryption (ABE) using Efficient RSA (Rfvest, Shamir, Adleman) schema and Ring Based Fully Homomorphic Encryption (RBFHE) schema for uploading user data.
