MULTI LEVEL ENCRYPTION CIPHERTEXT USING MULTI BLOCKS AND SECURE DATA ACCESS POLICY IN CLOUD COMPUTING

An emerging paradigm in computing that aims to provide customers with the right solutions are cloud computing. Whether multi-layer authentication or multi factor verification makes accessing data stored in a cloud computing environment simple, it relies mostly on many current technologies such as virtualization, grid computing, etc. Results from the simulation show that three-tier authentication is more efficient than competing methods, lending credence to its viability as a cloud authentication solution. To enhance cloud safety and provide effective privacy security, a multi-level micro-access limitation formula is first suggested. Cloud data goes through many layers of indexing. Security is used to varying degrees during data transmission. The advantages listed in the configuration papers are used to assess the customer's requests for reliable accessibility. Data stored in the cloud is similarly encrypted using a key that is owned by the data owner. Both the efficacy and precision of cloud security and privacy protection are improved by this method.
