The tradition network sharing models on existing mobile architecture is a challenging for the mobile operator to cope the future competitive market while increasing average revenue per user. In fact, to sustain the future data tsunami, the operators are already investing in their network. However, they are not yet capturing their investments. The average revenue per user has declined. Moreover,...

One of the reasons why Web APIs are more used to consume open data compared to SPARQL endpoints is the expertise required to use the query language. Therefore, a tool for sharing and reusing existing real queries could help developers on adopting Linked Data. We propose BASIL, a cloud platform that supports sharing and reusing SPARQL queries. In BASIL, loaded queries generate Web APIs that can ...

In the first part of this report we present a survey of the state of the art in searchable encryption and its relevance for cloud computing. In particular we focus on the OpenStack open-source cloud platform and investigate which searchable encryption schemes are more amenable for adoption in conjunction with platforms based on OpenStack. Based on that survey we chose one of the schemes to impl...

Cloud computing is a revolutionary computing environment, which allows user a flexible, on-demand, and low-cost usage of computing resources, but as the data is outsourced to some cloud servers, and various privacy issues emerge from it. To handle these security problems, various schemes based on the Attribute-Based Encryption have been proposed recently. Attribute-based Encryption (ABE) is a c...

To realize privacy data protection efficiently in hybrid cloud service, a hierarchical control architecture based multi-cluster MapReduce programming model (the Hierarchical MapReduce Model, HMR) is presented. Under this hierarchical control architecture, data isolation and placement among private cloud and public clouds according to the data privacy characteristic is implemented by the control...

One way to establish trust in a service is to know what code it is running. However, verified code identity is currently not possible for programs launched on a cloud by another party. We propose an approach to integrate support for code attestation—authenticated statements of code identity—into layered cloud platforms and services. To illustrate, this paper describes TapCon, an attesting conta...

This study examines the acceptance of cloud computing services in government agencies by focusing on the key characteristics that affect behavioral intent. The study expanded upon the technology acceptance model by incorporating contextual factors such as availability, access, security, and reliability. The research model was empirically verified by investigating the perception of users working...

Data deduplication is the specialized and resent compression technology in the cloud computing. In hybrid cloud server storing of repeated data courses many storage management challenges. The data deduplication overcome this challenges by reduce the copy of data and save the space in the cloud service provider (CSP). It also saves the bandwidth of the storage cloud. This deduplication method pr...

-The Cloud Computing is the new vision of computing utility, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or cloud provider interaction. Cloud computing technologies can be implemented in a wide variety of architectures, under different service and deployment models, and can coexist wit...

Cloud dominates the IT enterprises by way of its computing services. One of the services provided by the cloud is data storage. Cloud storage mainly supports Small and Medium scale Enterprises (SMEs) by reducing their capital investments and maintenance of storage servers. Most of the SMEs are outsourcing their data to cloud storage. Enterprises’ data that are forwarded to the cloud have to be ...
