Many future applications, such as distributed social networks, will rely on public-key cryptography, and users will want to access them from many locations. Currently, there is no way to store private keys in the cloud without placing complete faith in a centralised operator. We propose a protocol that can be used to share secrets such as private keys among several key recovery agents, using a ...

In the cloud environment, resources are shared among all of the servers, users and individuals. So it is difficult for the cloud provider to ensure file security. As a result it is very easy for an intruder to access, misuse and destroy the original form of data. In case of compromise at any cost; entrusting cloud is of no use. A need for “practically strong and infeasible to get attacked” tech...

Cloud computing appeared as the most common paradigm in the time being that provides calculations and storage resources by when used – pay method. Users can exploit cloud resources from anywhere at any time without maintenance cost. Flexibility in resource allocation enabled cloud services to be effective in delivering with reasonable cost. However, transfer data to cloud make it vulnerable to ...

AppScale is a scalable, distributed, and fault tolerant cloud runtime system that we have developed at the University of California, Santa Barbara as part of our research into the next generation of programming systems [5, 3]. In particular, AppScale is a cloud platform, i.e. a platform-as-a-service (PaaS) cloud fabric, that executes over cluster resources. The cluster resources underlying AppS...

Major challenges in cloud computing are security and privacy because of its multi-tenancy nature and the subcontracting of infrastructures. Enterprises, government organizations and educational institutions are quickly accepting cloud services for their businesses. Cloud events need to be developed so that these organizations can be assured of security in their businesses and can choose an appr...

Cloud Computing ermöglicht es, Software “on-demand” über das Internet zu liefern. Dieses Dokument zeigt wie die Plattform CollaboCloud aufgebaut ist und als SaaS in einer Cloud der Hochschule Furtwangen gehostet wird. CollaboCloud kommt an der Hochschule Furtwangen in den Bereichen Projektzusammenarbeit und Forschungskollaboration zum Einsatz. Besonders interessant sind die Möglichkeiten der Bi...

Most of the existing ways for strengthening users’ confidence in uploading private data to a cloud platform stress too much on security. On the contrary, cloud computing must be open and distributed. Moreover, it should provide highly robust, secure, and quality services to users. Therefore, establishing a balance between the performance and the security of cloud platforms is necessary. In this...

Cloud computing has elevated IT to newer limits by offering the market environment data storage and capacity with flexible scalable computing processing power to match elastic demand and supply, whilst reducing capital expenditure. However the opportunity cost of the successful implementation of Cloud computing is to effectively manage the security in the cloud applications. Security consciousn...

Recent years have seen significant growth in the cloud computing market, both in terms of provider competition (including private offerings) and customer adoption. However, the cloud computing world still lacks adopted standard programming interfaces, which has a knock-on effect on the costs associated with interoperability and severely limits the flexibility and portability of applications and...

With the rapid growth of cloud adoption in both private and public sectors globally, cloud computing environments have become a new battlefield for cyber crime. In this paper, the researchers present the results and analysis of a survey that had been widely circulated among digital forensic experts and practitioners worldwide on cloud forensics and critical criteria for cloud forensic capabilit...
