Privacy-Preserving Public Auditing for Secure Cloud Storage using ElGamal Public Key Encryption Algorithm

The Cloud registering is a most recent engineering which gives different administrations through web. The Cloud server permits client to store their data on a cloud without stressing over accuracy& trustworthiness of data. Cloud data stockpiling has numerous preferences over nearby data stockpiling. Client can transfer their data on cloud and can get to those data at whatever time anyplace without any extra load. The User doesn't need to stress over capacity and support of cloud data. Anyway as data is put away at the remote place how clients will get the affirmation about put away data. Henceforth Cloud data stockpiling ought to have some system which will determine capacity rightness and respectability of data put away on a cloud. The real issue of cloud data stockpiling is security. Numerous specialists have proposed their work or new calculations to accomplish security or to resolution this security issue. In this paper, we propose a safe cloud storage framework supporting protection safeguarding open reviewing. We further augment our result to empower the TPA to perform reviews for numerous clients all the while and effectively. Broad security and execution investigation demonstrate the proposed plans are provably secure and very effective.
