Emerging storage cloud systems provide continuously available and highly scalable storage services to millions of geographically distributed clients. A secure access control mechanism is a crucial prerequisite for allowing clients to entrust their data to such cloud services. The seamlessly unlimited scale of the cloud and the new usage scenarios that accompany it pose new challenges in the des...

In recent years, cloud storage service has become a faster profit growth point by providing a comparably scalable, position-independent,low -cost platform for client’s data. Since cloud computing environment is constructed based on open architectures and interfaces. It has the capability to incorporate multiple internal and external cloud services together to provide high interoperability there...

0 Abstract The increasing popularity of cloud storage services has led many companies to migrate their data into clouds for high availability whilst saving infrastructure constructions. Within the last few years, the architectures of most major cloud storage providers have evolved from single data center to multiple data centers, across different geo-locations. This architecture help improve th...

Streaming media is widely adopted by thousands of applications in cloud computing, how to effectively protect streaming media contents is a new challenge. In this paper, we propose an efficient online digital rights management (DRM) scheme supporting dynamic license in cloud computing. The content provider encrypts media content and outsources the encrypted content to cloud storage, while the u...

The cloud computing paradigm with its elastic payas-you-go model, “infinite” scalability and “always-on” availability arguably changes the landscape of services and systems. However, so far, cloud proliferation has not lived up to expectations in the enterprise segment. Often cited issues include confidentiality and integrity, but also reliability and consistency. In this paper, we argue for th...

The ubiquity of the cloud computing allows the mobile devices to connect and use the traditional cloud computing services [1]. However, unlike the normal computing machines, the mobile devices are resource constrained. The precincts of low processing power, less storage capacity, limited energy, and the capricious internet connectivity does not allow the compute and storage mandating applicatio...

Public cloud storage services are gaining in popularity and several commercial actors are offering their services for users, however, not always with the security and privacy of their users as the primary design goal. This paper investigates side channels in public cloud storage services that allow the service provider, and in some cases users of the same service, to learn who has stored a give...

Data Storage outsourcing in cloud computing is a rising trend which prompts a number of interesting security issues. Provable data possession (PDP) is a method for ensuring the integrity of data in storage outsourcing. Remote integrity checking is crucial in cloud storage, here using multi cloud. It can help the clients to check their whole outsourced data by without downloading. This research ...

Cloud computing is an emerging technology; it has gained an importance because of the advantages beyond this technology. The user will be using the software service provided by the cloud service provider without installing and maintaining it and user is paying purely based on his usage. Cloud storage technology frees the user from the load of local data storage and maintenance. The challenges o...
