Cloud computing technology enables individuals and organizations to gain access to huge amount of computing resources without capital investment in pay per use fashion. Cloud users can outsource the valuable data to cloud as the local system can’t handle huge amount of data. However, the data when stored in third party servers, its confidentiality is a concern. The cloud has a collection of sto...

Cloud Security threats have greatly hindered the development of Cloud Computing and the promotion of cloud application, so how to protect the data stored in the cloud is not only the core issue of security, but also the biggest challenge of development. As these problems above, a trust-control architecture based on the concept of Cloud Storage Service was creatively proposed. Based on the struc...

With the development of cloud computing, and as the basis of data services, security problems of cloud storage are growing more attention. Based on distributed storage, multidomain and multi-tenant characteristics, combined with access control technologies, this paper sets up the Role-based Access Control using Ontology and domians in Cloud Storage (DOnto_RBAC), which could provide a concise an...

The promising benefit of cloud computing is outsourcing of data service, by which the data owners stores their data in the public data centers by economically saving their capital investment towards data management. Cloud Storage provides users with abundant storage space and makes it user friendly for immediate acquiring of data, which is the foundation of all kinds of cloud applications. Data...

Cloud computing has become an important thing in computer field. Cloud computing takes information processing as a service, such as storage and computing. Data integrity is important thing in cloud storage. In certain situations, clients should store their data such as image or text in multi cloud. When the client stores his/her data on multicloud servers, the distributed storage and integrity ...

The paper presents the vulnerabilities of cloud storage and various possible attacks exploiting these vulnerabilities that relate to cloud security, which is one of the challenging features of cloud computing. The attacks are classified into three broad categories of which the social networking based attacks are the recent attacks which are evolving out of existing technologies such as P2P file...

A cloud computing is becoming increasingly popular; cloud storage services attract more attentions for their high security and availability with a low cost. Cloud storage is expected to become the main force of the future storage market. As a key technology of cloud computing, replication faces new challenges, especially replica consistency. The intrinsic characteristic heterogeneous of cloud a...

Using cloud storage servers to manage large amounts of data has gained increased interest due to their advantages (like availability and scalability). A major disadvantage of cloud storage providers, however, is their lack of security features. In this article we analyze a cloud storage setting where confidentiality of outsourced data is maintained by letting the client encrypt all data records...

Load balance just reasonably allocate request from users to each edge cloud storage servers. It can avoid overloading or congestion to ensure data transmission efficiency. Referring to idea of ant colony algorithm, the paper brought out Content Delivery Load Balance Algorithm Based on Probability Matching (CDLBA-PM) algorithm. The method calculated access probability of each edge cloud storage ...

Cloud users store their data in the cloud environment which is privileged by the service provider. Cloud users can access their cloud storage. Here we propose a flexible distributed storage integrity auditing mechanism, utilizing the homomorphic token and distributed erasure-coded data. The proposed design allows users to audit the cloud storage with very lightweight communication and computati...
