Abstract
Abstract: Data storage and sharing services within the cloud, users can easily modify and share data as a bunch. to make sure share data integrity are often verified publicly, users within the group must compute signatures on all the blocks in shared data. Different blocks in shared data are generally signed by different users thanks to data modifications performed by different users. Encryption schemes available for data privacy but it limits the number of functions exhausted storage system. Building a secure storage system that supports multiple functions is hard when the storage system is distributed and has no central authority. a brand-new idea is proposed proxy re-encryption scheme for decentralizes erasure code for defending the distributed system. The easy method, which allows an existing user to download the corresponding a part of shared data, is inefficient because of the big size of shared data within the cloud. We propose a unique public auditing mechanism. Moreover, our mechanism is in a position to support batch auditing by verifying multiple auditing tasks simultaneously.
