Cloud Computing represents an evolution of information systems. This technology is suitable for large groups but also for SMEs that offers a very high computing power at lower costs. It is used to interconnect several organizations disregarding their geographic location, and transforms current computer infrastructures and services. Cloud computing brings a new approach to computing, a different...

Recent Technologies that reach end users are those which provide services for all their needs. Cloud computing is a technology where service is provided for all end user’s needs and requests. As we move deeper into an era in which data usage and the storage capacity are increased double year by year, some of the major companies are mainly concentrated on demand storage option like cloud storage...

In this paper, wehave propose a user authentication scheme for cloud computing. The proposed framework providesmutual authentication and session key agreement in cloud computing environment. The scheme executesin three phases such as server initialization phase, registration phase, authentication phase. Detailed security analyses have been made to validate the efficiency of the scheme. Further,...

Cloud computing is a new terminology achieved by distributed, parallel and grid computing and a design pattern for large, distributed data centers. Cloud computing offers end customers a pay as go model. Quality of service plays an important factor in distributed computing. Cloud computing provides different types of resources like hardware and software as service via internet. Under cloud comp...

Data integrity is one of the major concerns with cloud data storage for cloud user. Besides, the cloud user’s constrained computing capabilities make the task of data integrity auditing expensive and even formidable. In recent years, many public data integrity verification schemes have been proposed, however, most of them are vulnerable to an efficient active attack, which means that the active...

 In recent years, mobile networks have faced with the increase of traffic demand. By emerging mobile applications and cloud computing, Mobile Cloud Computing (MCC) has been introduced. In this research, we focus on the 4th and 5th generation of mobile networks. Data Centers (DCs) are connected to each other by high-speed links in order to minimize delay and energy consumption. By considering a ...

since software systems play an important role in applications more than ever, the security has become one of the most important indicators of softwares.cloud computing refers to services that run in a distributed network and are accessible through common internet protocols. presenting a proper scheduling method can lead to efficiency of resources by decreasing response time and costs. this rese...

Despite the surge in activity and interest in cloud computing, there are significant and persistent concerns about cloud computing, particularly with regard to trusting the cloud platform in terms of confidentiality, integrity and availability of user data stored through these applications. These factors are significant in determining trust in cloud computing and thus provide the foundation for...

Cloud Computing as a computing paradigm recently emerged to a topic of high research interest. It has become attractive alternative to traditional computing environments, especially for smaller research groups that can not afford expensive infrastructure. Most of the research regarding scientific computing in the cloud however focused on IaaS cloud providers. Google App Engine is a PaaS cloud f...
