In this paper, we present a novel approach to cloud service security certification. This approach could be used to: (a) define and execute automatically certification models, which can continuously and incrementally acquire and analyse evidence regarding the provision of services on cloud infrastructures through continuous monitoring; (b) use this evidence to assess whether the provision is com...

Cloud computing becomes one of the emerging technology on now a days to share and manage their data in organization , because of its forcefulness, small communication cost and everywhere environment. Privacy preservation concern in the cloud computing becomes arise several security challenges since information stored in the cloud data is easily outsourced anywhere at any time. To manage this pr...

Cloud computing has become one of the most important technologies for reducing cost and increasing productivity by efficiently using IT resources in various companies. The cloud computing system has mainly been built for private enterprise, but public institutions, such as governments and national institutes, also plans to introduce the system in Korea. Various researches have pointed to securi...

We remark that the scheme [IEEE TPDS, 27(1), 2016, 40-50] is flawed because the group manager cannot complete his computational task in the registration phase. Actually, they have misunderstood the concept of public key which is usually associated with an asymmetric encryption algorithm. Besides, the mechanism that the group manager has to re-encrypt all data stored in the cloud after a member ...

Cloud system is gaining the importance in public environment. But security is always a critical challenge while sharing the valuable information. In this work, a high level integrated security model is presented for managing large data on cloud system. In this work, a RSA integrated SHA method is presented to provide the secure file management in distributed cloud. The proposed authentication a...

A new data management cloud platform is presented. The platform is to be applied for global air pollution monitoring purposes to assess the pathway of pollutants in the atmosphere. For this purpose a set of interconnected services and tools will be developed and hosted in the JINR cloud.

The extent and importance of cloud computing is rapidly increasing due to the ever increasing demand for internet services and communications. Instead of building individual information technology infrastructure to host databases or software, a third party can host them in its large server clouds. Large organizations may wish to keep sensitive information on their more restricted servers rather...

In these recent years cloud computing paradigm has achieved widespread adoption. Its success is because of large customers’ ability to use services on demand with a payas-you go pricing model. Low costs and high flexibility make migrating to the cloud computing. Although having advantages, many companies hesitated to move to the cloud mainly because of conflicts related to the service facing th...
