Security For Dynamic Data Storage in Cloud

pdf PDF


Cloud provides variety of services and resources dynamically through internet. In cloud, the users avail the storage space provided by cloud service providers. In this , the users do not have direct control over the remotely stored data. The imperative security concerns in cloud are the integrity and confidentiality of data. To preserve the privacy of dynamically changing data, an efficient approach maintaining the confidentiality and assuring the integrity of data is proposed. In this scheme, public auditability is enabled by introducing a third party auditor . We ensure that the data stored in the untrusted cloud server is confidential and consistent by 2-keys Symmetric Encryption. Unlike other encryption algorithms, this needs lesser computation overhead. Simulation environment is set up with the eucalyptus tool. The performance analysis and simulation results prove that our proposed scheme is secure and proficient by reducing the computation cost of server and user.
