Cloud computing technology use central server and provide applications as services to users. The organization can take advantage of reducing the cost of hardware and software ownership and maintenance. Many surveys proved cloud computing reduces total cost of ownership. But due to centralized server approach there is always risk to system security. All applications required by different set of ...

Large number of clients like to store data onto public cloud server (PCS) due to increase in advancement in cloud computing. As a result the new security problems are in need to be solved to help large number of clients in processing their data on public cloud servers. When the clients are not allowed to access the public cloud servers, they will be forwarded to proxy servers to process their d...

In order to provide the agricultural works with customized, visual, multi-perspective and multi-level active service, we conduct a research of digital agricultural information resources sharing plan based on cloud computing to integrate and publish the digital agricultural information resources efficiently and timely. Based on cloud computing and virtualization technology, we establish a cloud ...

Due to its low cost, robustness, flexibility and ubiquitous nature, cloud computing is changing the way entities manage their data. However, various privacy concerns arise whenever potentially sensitive data is outsourced to the cloud. This paper presents a novel approach for coping with such privacy concerns. The proposed scheme prevents the cloud server from learning any possibly sensitive pl...

Nowadays, enterprises widely deploy Network Functions (NFs) and server applications in the cloud. However, processing of sensitive data and trusted execution cannot be securely deployed in the untrusted cloud. Cloud providers themselves could accidentally leak private information (e.g., due to misconfigurations) or rogue users could exploit vulnerabilities of the providers’ systems to compromis...

Cloud computing is mainly used for storing client information in the server as the cloud storage without overhead of storage and maintenance, which is very helpful for clients because it is pay per use process. Here security is main problem for both client and server. In This paper we describe secure cloud storage with privacy preserving and data dynamics by using Third Party Verifier (TPV). Th...

Cloud computing is a computing environment, where a large pool of systems are connected in private or public networks, to provide dynamically scalable infrastructure for application, data and file storage. With the advantage of this technology, the cost of computation, application hosting, content storage and delivery is reduced significantly. The idea of cloud computing is based on a very fund...

Cloud computing is a promising profitable infrastructure framework that assures to eradicate the requirement for sustaining expensive computing facilities by companies and institutes alike. Information systems supported on the cloud computing and peer-to-peer (P2P) model are now receiving popularity. In the cloud computing form, a cloud of servers sustain few clients with different types of ser...

As the Cloud Computing technology becomes mature, the need increases rapidly to store sensitive data securely on the cloud server. Since the cloud is not trusted, the data should be stored in an encrypted form at the server. An inherent problem is how to query the encrypted data efficiently. Recently, some searchable encryption schemes have been proposed in the literatures. Although the existin...

We propose a system that uses cloud storage as an hourly back-up system while providing a fully featured filesystem for distributed storage. We mount a fully featured filesystem stored in the cloud to a local server and take advantage of a very large local server cache so that we can have similar performance to a central local server while having the reliability of a cloud system. We use a modi...
