Recently, hybrid cloud computing paradigm has be widely advocated as a promising solution for Software-as-a-Service (SaaS) providers to effectively handle the dynamic user requests. With such a paradigm, the SaaS providers can extend their local services into the public clouds seamlessly so that the dynamic user request workload to a SaaS can be elegantly processed with both the local servers a...

Cloud computing, with the paradigm of computing as a utility, has the potential to significantly tranform the IT industry. Attracted by the high efficiency, low cost, and great flexibility of cloud, enterprises began to migrate large parts of their networks into cloud. The cloud becomes a public space where multiple “tenants” reside. Except for some public services, the enterprise networks in c...

D espite cloud computing’s enormous popularity and high profile, many companies have been dissatisfied because they haven’t found what they want in a single cloud architecture. Private clouds, which organizations run internally, are secure, accessible without Internet availability, and customizable. Public clouds run over the Internet and are scalable, less costly, and simple to adopt and use. ...

Yinqian Zhang: Cache-based Side-Channel Attacks in Multi-Tenant Public Clouds and Their Countermeasures (Under the direction of Michael Reiter) Cloud computing is gaining traction due to the business agility, resource scalability and operational efficiency that it enables. However, the murkiness of the security assurances offered by public clouds to their tenants is one of the major impediments...

CLOUD computing has emerged as a disruptive technology andnew computing paradigm inwhich IT resources (hardware, software, applications, data storage, computing capacity, etc.) are provided as services over the Internet, through “everything-as-a-service”. It builds on the foundations of distributed computing, grid computing, virtualization, service orientation, etc. Cloud storage, which is one ...

Cloud computing is one of the most important technology of networking which is widely used in these days. Cloud computing has some security issue also. There are several types of attacks which can be launch on cloud very easily and has many serious effects on the network. This paper discussed the proposed scheme to overcome the adversary effects of virtual side channel effects. Keywords— Privat...

Now a day's cloud computing became an attractive area of research and practices over the last few years. An increased number of private and public sector organizations have either adopted cloud company based solutions or seriously consider moving to cloud computing. In this paper we initiated a project designing and setting up a private cloud infrastructure in an academic environment. The ...

With cloud computing, data owners are motivated to outsource their data from local sites to public cloud for great flexibility and economic saving. Recently, some research consider the problem of secure and efficient public data integrity auditing for shared dynamic data. But this scheme is not secure against collusion of cloud storage server. An efficient public integrity auditing with a secur...
