Abstract: - Cloud computing is an on demand service where the user can obtain computer resources via the internet. Due to increase the advantages of cloud computing the individual users and organizations are store their data in cloud storage servers. But storing data in a third party cloud system is a serious issue. To avoid this issue the data’s are encrypted before storing in storage server. The normal encryption system provides security but it does not support data integrity on the cloud storage server. To address this issue the research work proposed an Elliptic Curve Digital Signature algorithm, it provides data integrity and data origin authentication. To support a dynamic data modification the Merkle Hah Tree construction is also used. The User’s data’s are encrypted by using an efficient Elliptic Curve Digital Signature Algorithm (ECDSA). The encrypted data’s are divided in to blocks by using Merkle hash tree, the authenticated user can perform all the operations like insert, delete and update at the particular block in storage server itself. To support the efficient handling of auditing tasks the third party auditor is used to verify the integrity of the dynamic data operations on the cloud storage server. Compare with existing system this research work provides a highly secure and efficient cloud storage server.
