Secure and Reliable Data sharing scheme using Attribute-based Encryption with weighted attribute-based Encryption in Cloud Environment

The field of data management has been reformed by the Cloud computing technologies which offered valuable establishments and amended storage restrictions barriers for its users. In large enterprises cloud extensively used implementation due to benefits. There are still lot security threats in cloud. owners suffer from privacy issues considered as one major concerns. Data can be secured employing some existing methods such Attribute-based Encryption (ABE). Yet, prevailing largely over this research a access control is proposed using Advanced Standard (AES) combined with weighted attribute-based (AES-WABE). To encrypt data, policies weight assigned according significance each attribute. outsourced stored service provider attribute authority based on that updates attributes. minimize computational overload file accessed receiver corresponding weight. procedure provides resistance collusion, multiple user fine-grained protection, reliability efficiency. On concerning collaboration confidentiality, performance rating done related Cipher-text Policy–Attribute-based (CP-ABE) hybrid encryption (HABE) scheme, flexibility, limited decryption, full delegation, verification partial signing.
