There is a growing demand for cloud storage services such as Dropbox, Box, Syncplicity and SugarSync. These public cloud storage services can store gigabytes of corporate and personal data in remote data centres around the world, which can then be synchronized to multiple devices. This creates an environment which is potentially conducive to security incidents, data breaches and other malicious...

Identity-Based Provable data possession (PDP) is a technique for ensuring the integrity of data in storage outsourcing construction of an efficient scheme for distributed cloud storage to support the scalability of service and data migration, in which of multiple cloud service providers to cooperatively store and maintain the clients’ data. Cloud computing has become an important thing in compu...

Cloud storage is provided as a service in order to keep pace with the increasing use of digital information. It can be used to store data via networks and various devices and is easy to access. Unlike existing removable storage, many users can use cloud storage because it has no storage capacity limit and does not require a storage medium. Cloud storage reliability has become a topic of importa...

Cloud computing provides a service based on internet for several shared resources and system software across various environment. For secure cloud storage the process of encryption of the data to the users for various needs has been brought by the delegated access control method. Generally storage in public cloud requires high communication, heavy load due to maximum storage and high computatio...

Cloud storage is one of the most popular services techniques in cloud computing environment. A crucial problem to be addressed in the cloud storage system concerns the security mechanism of protecting the private data and sharing data with other users. Cloud storage services are inherently insecure as the management technique of the data in the cloud storage is controlled by third parties beyon...

Cloud computing technology enables users and enterprises with various capabilities to store and process their data in either privately owned cloud or on a third-party server in order to make data accessing mechanisms much more easy and reliable. This service releases the burden of huge local data storage and their preservation by outsourcing mass data to the cloud. Apart from reducing the stora...

In the age of cloud computing, cloud users with a limited amount of storage can outsource their data to remote servers. The cloud servers, in lieu of monetary benefits, offer retrievability of their clients’ data at any point of time. Secure cloud storage protocols ensure the integrity of the outsourced data that can be dynamic (or static) in nature depending on whether the client can (or canno...

Cloud computing provides scientists a platform that can deploy computation and data intensive applications without infrastructure investment. With excessive cloud resources and a decision support system, large generated datasets can be flexibly 1) stored locally in the current cloud, 2) deleted and regenerated whenever reused or 3) transferred to cheaper cloud service for storage. However, due ...

This paper focuses on studying cloud storage data protection model and implementing encrypted storage of user data in double-key form. User data are encrypted with symmetric encryption algorithm and this secret key is encrypted with asymmetric encryption algorithm. The private key is managed and controlled by users. In this way, users guarantee the security of their own data with the sole priva...
