Cloud computing is the fast growing and the dominant field of Information technology (IT) industry. It proposes on demand and cost effective services such as Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS). Many security challenges are drawn from these services in cloud environment such as abuse of cloud services, data security, malicious insider and cyber-attacks. Although various access control policies and models such as Mandatory Access Control (MAC) and Role Based Access Control (RBAC) are existing, but these are not suitable for Cloud access control requirements. In this paper, we analyze and identify different important gaps of the conventional access control schemes based on the their demerits and cloud access requirements. We also propose a Combinatorial Batch Codes Based Access Control (CBCBAC) model, which fulfill all the cloud access control requirements. Our approach ensures the secure and efficient sharing of resources among various non-trusted tenants and also has the capacity to support different access permission to the same user for using multiple services securely. We also implement a prototype of our work which depicts the effective access control in the cloud environment.

Industry 4.0: Is It Time for Interaction Design Craftsmanship?

引用

DESIGN JOURNAL 2017年第sup1期20卷 S2735-S2745页

作者： Petrelli, Daniela Sheffield Hallam Univ Art & Design Res Ctr Sheffield S Yorkshire England

The technological innovation of Industry4.0 opens up new possibilities for bespoke and unique designs all rooted in the same technology and supported by the same services. Taken together, Cyber-Physical Systems, Cloud computing and internet of Things offer a neutral platform for the creation of hybrid digital physical objects. The economy of scale is reached by sharing the same technology across different projects and potentially very different domains. This vision is illustrated by the work done in the meSch project and its platform for the production of novel interactive experiences in museums. Six installations designed by recombining the same electronic components and the same services are used as a case study. They show how the meSch platform is aligned with Industry4.0 principles of enabling dynamic composition, supporting distributed production, and monitoring use for service improvement. As a platform it supports single-piece production and empowers designers to create bespoke solutions with the same technological core.

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, selfservice 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 of tasks are executed simultaneously, an effective Task Scheduling is required to gain better performance of the cloud system. Various Cloud-based Task Scheduling algorithms are available that schedule the user's task to resources for execution. Due to the novelty of Cloud computing, traditional scheduling algorithms cannot satisfy the cloud's needs, the researchers are trying to modify traditional algorithms that can fulfil the cloud requirements like rapid elasticity, resource pooling and on-demand self-service. In this paper the current state of Task Scheduling algorithms has been discussed and compared on the basis of various scheduling parameters like execution time, throughput, makespan, resource utilization, quality of service, energy consumption, response time and cost.

Large-scale internet applications provide service to end users with servers, which may be located at geographically distributed data centers. Users may require different delay constraints for different services. To meet the service delay requirements to end users, the data centers must provide enough server resources which incur a large amount of electricity and dollars cost. In this paper, we tackle the problem of minimizing electricity cost under diverse delay requirements of different services for different users in a multi-electricity-market environment. We propose two algorithms to reduce the electricity cost, taking into account the location diversity and the time diversity of electricity price. Our simulation results demonstrated that the proposed algorithms were effective in terms of the reduction of the electricity cost while satisfying the diverse delay constraints.

The human activity recognition in the IoT environment plays the central role in the ambient assisted living, where the human activities can be represented as a concatenated event stream generated from various smart objects. From the concatenated event stream, each activity should be distinguished separately for the human activity recognition to provide services that users may need. In this regard, accurately segmenting the entire stream at the precise boundary of each activity is indispensable high priority task to realize the activity recognition. Multiple human activities in an IoT environment generate varying event stream patterns, and the unpredictability of these patterns makes them include redundant or missing events. In dealing with this complex segmentation problem, we figured out that the dynamic and confusing patterns cause major problems due to: inclusive event stream, redundant events, and shared events. To address these problems, we exploited the contextual relationships associated with the activity status about either ongoing or terminated/started. To discover the intrinsic relationships between the events in a stream, we utilized the LSTM model by rendering it for the activity segmentation. Then, the inferred boundaries were revised by our validation algorithm for a bit shifted boundaries. Our experiments show the surprising result of high accuracy above 95%, on our own testbed with various smart objects. This is superior to the prior works that even do not assume the environment with multi-user activities, where their accuracies are slightly above 80% in their test environment. It means that our work is feasible enough to be applied in the IoT environment. © 2016 ACM.

Virtual network management is a basic component provided by cloud computing system. In cloud environment, the fact that VMs in the same subnet are located in different hosts, the traffic of VMs attached to different users should be isolated, the VM would be migrated to other hosts makes network management different from that in physical network. technology like overlay and SDN is usually introduced to establish a reliable and efficient virtual network management scheme. However, there are many drawbacks such as flexibility and hardware costs in most schemes introducing technology above-mentioned. We addressing these problems by designing a scheme on the hyper-visor layer of physical hosts based on overlay and SDN technology, which means the tradition virtual network can be easily transformed to our system without purchasing new devices supported OpenFlow or VXLAN(a kind of technology in overlay) protocol. Besides additional functions like monitor and traffic mirror can be customized by users' needs for the system's flexibility and scalability the SDN technology endowing. We also design a distributed Virtual Router(DVR) on each host to solve the general problem of traffic between internet and Intranet concentrating in most schemes. The experimental evaluation shows that our system has achieve the basic intercommunication under the situation of tenant isolation and its performance of communication between internet and Intranet acts obviously better than that in OpenStack scheme for our DVR design.

Cloud computing is an internet-based distributed system architecture to provide the customers with services and resources in a scalable and self-manageable fashion. Whatever the user needs and wherever he demands it-Cloud can deliver the regarding software services, platform or infrastructural resources. Services are furnished by software whereas resources are a complex of virtualized computing facilities, storages, and networking hardware provided by the Cloud for end users and enterprises. Therefore, the Cloud computing principle leads to a new paradigm in computer architecture. We can divide the whole system into two parts: • the front-end which consists of different kind of mobile devices like tablets, smart phones, PCs, or simply embedded systems, and regarding software as well as • the back-end, which is the Cloud infrastructure consisting of resources and services (as public, private, hybrid, or federated Cloud) with a centralized view for users. © Springer international Publishing Switzerland 2016.
