In cloud storage, the data owner and data users can easily perform cooperative work on shared data. In this paper, we focus on operation behavior auditing in shared cloud storage, which is significant for the avoidance of potential crimes in the cloud and equitable accountability determination for the forensic investigation in shared cloud. We first introduce a novel secure public auditing model for...
Internet of Things (IoT) serves not only as an essential part of the new generation information technology but as an important development stage in the information era. IoT devices such as unmanned aerial vehicles, robots and wearable equipments have been widely used in recent years. For most organizations' inner networks, innumerable dynamic connections with Internet accessible IoT devices occur...
from the viewpoint of new malicious code signatures, Symantec created 2,895,802, Countermeasures against these cyber security threats. Consequently, an organization in one country may be attacked by malware whose countermeasures are already known and implemented within another organization in another country. Such incidents occur due to the lack of exchanging of information among organizations. This...
Cloud Computing is a paradigm of both parallel processing and distributed computing. It offers computing facilities as a utility service in pay as par use manner. Virtualization, self-service provisioning, elasticity and pay per use are the key features of Cloud Computing. It provides different types of resources over the Internet to perform user submitted tasks. In cloud environment, huge number...
Network Function Virtualization (NFV), Cloud Computing, and Software Defined Networking (SDN) are closely related technologies and their combination can provide complete and high quality services to the end users. Multiple Virtualized Network Functions (VNFs) can be implemented as Virtual Machines (VMs) on top of cloud servers, while the traffic flow traversing these VNFs can be facilitated through...
Cloud Computing is an on-demand access to a shared pool of resources. Vendor's of cloud computing provide application and enable technology, infrastructure, hardware, software, and integration for client. The flip side of the cloud computing is availability and performance of their internet connection [8]. If excessive network latency is causing the application to spend a large amount of time waiting...
Once failures occur in a cloud datacenter accommodating a large number of virtual resources, they tend to spread rapidly and widely, impacting on many cloud users (tenant owners). One of the best ways to prevent a failure from spreading in the system is identifying signs of the failure before its occurrence and deal with it proactively before it causes serious problems. Although several approaches...
Due to a few realistic challenges (e.g. lack of protocol support, limitation of NAT and firewall, etc), it is difficult to access residential multimedia services from heterogeneous network environment. In this paper, we propose a system architecture for accessing residential multimedia services from either local or remote networks. The proposed solution includes UPnP-based local multimedia access,...
To move applications to the cloud is not only a technical decision but also a business-oriented decision, in which both business and technical factors (e.g. transformation effort, multi-tenancy and auto-scaling enablement, scalability and extensibility) should be considered. However, existing approaches and tools do not support a consumable business oriented cloud transformation decision to select...
