In the cyber-physic power system (CPPS) scenario, an increasing number of new devices, such as large-scale electric meters, embedded controllers and powerful computing devices are introduced into the power system. However, the architecture of present power system limits the seamless integration of the information system and physical systems. In this paper, a decentralized CPPS-fog architecture is proposed to address this issue. The proposed architecture distributes computing, communication storage, and control these services to the edge network along the cloud-to-thing continuum while the latter is commonly used in the smart grid. By applying the new architecture to the power system, the intelligence resources of the power system are effectively allocated to the parts closer to end users. Moreover, the realtime monitoring, on-line simulation, information integration, large-scale distributed control, and information security protection are easily achieved. The feasibility and advantages of the CPPS-fog architecture are demonstrated by the application in an island micro CPPS grid project.

In this paper we proposed a novel technique to store the data authentically in the cloud. Since because of elastic property from the point of view of storage space cloud is most popular to store data. cloud is inquiring about stores data on it. Therefore, security is must for store data for preserving it from malicious attackers as well as there may be leakage in stored data security. Many times there is necessary condition for hiding the user or data owner identity from cloud. A technique use in this paper shows anonymous authentication for stored data on cloud. This system preserves the identity of the users before storing it on cloud. The main aim of this paper is only valid user have ability to encrypt stored data with help of accessing its control features. The basic idea behind this scenario is to prevent stored data of cloud as well as its creation, modification etc. In this approach, cloud is familiar with access policies of every stored data also several KDCs are used for key management. Expensive operations are carried out easily in decentralized cloud system than centralized cloud system approach. The proposed system is implemented and tested in java with mysql database.

The construction of intelligent grain network is an important part of the national grain protection, and information platform is an important foundation to support the construction of Intelligent Grain Network. In order to make full use of the computing resources, to meet the needs of reliable storage and efficient management of all the information, the information platform structure of intelligent grain network based on cloudcomputing is proposed. In this paper, the architecture of the platform is presented, and the feasibility, advantages and problems of the new method are analyzed. According to the characteristics of intelligent grain network state monitoring, combined with the Hadoop cloudcomputing technology, this paper proposes the solution of intelligent grain network monitoring cloudcomputing platform. Research on cloudcomputing virtualization, distributed storage andparallel programming model and other issues, can achieve reliable intelligent grain network mass information storage and fast parallel processing.

cloudcomputing is a distributed andparallelcomputing model in which cloud service providers guarantees to provide services to client by pay-per-use model. Now-a-days, it is possible to share pool of virtualized computer resources, computational equipments, servers and storages in cloudcomputing environment. Allocating resources to highly prioritized job within estimated time is one of the biggest issues in job scheduling Job should be scheduled properly in order to provide higher throughput of the system and to maintain Quality of Service & Economic Principles of Management policies. To solve such scheduling problem, we have proposed prioritized job scheduling algorithm with parallelization technique. This algorithm mainly focuses on equally prioritized job problem and uses master-slave concept for job scheduling. We had compared and analyzed our algorithm with other priority based algorithm. Results shows that proposed algorithm improves performance and resource utilization of cloud and it reduces execution time period by balancing load across cloud.

A Cyber Physical Sensor System (CPSS) consists of a computing platform equipped with wireless access points, sensors, and actuators. In a Cyber Physical System, CPSS constantly collects data from a physical object that is under process and performs local real-time control activities based on the process algorithm. The collected data is then transmitted through the network layer to the enterprise command and control center or to the cloudcomputing services for further processing and analysis. This paper investigates the CPSS' most common cyber security threats and vulnerabilities and provides countermeasures. Furthermore, the paper addresses how the CPSS are attacked, what are the leading consequences of the attacks, and the possible remedies to prevent them. Detailed case studies are presented to help the readers understand the CPSS threats, vulnerabilities, and possible solutions.

With the development and application of business management information system, businesss own much more production and management softwares. Traditional computer labs can not deploy these application softwares and provide data sharing operations at the same time. In this paper, a cloud intelligence business platform based on the theory of framework and business model of SOA andcloudcomputing is discussed. A good software support will be achieved by virtue of ideas of hierarchical design of cloud platforms and virtualization technology to extend business hardware resources.

cloudcomputing facilitates end users to allow high performance computing applications by allocating resources on demand. This avoids large capital expenditure for small and medium sized enterprises having limited resources to obtain High Performance computing(HPC). In this paper, we propose a new distributed HPC model in self-built OpenStack public cloud under SDN infrastructure. For partitioning any task in HPC, domain decomposition strategy is used. We analyse different parallel computation topologies and benchmark their performances. The public cloud constructed under OpenStack platform is integrated with Opendaylight SDN controller for network controlling and monitoring. Also, we analyze and compare the performance of the OpenStack cloud with and without proposed distributed HPC system. The result shows that the speed performance of OpenStack cloud under SDN infrastructure is enhanced by implementation of our HPC system based on Hypercube algorithm and Mesh Algorithm.
