The 21st century will be the century of knowledge, and then knowledge management plays an increasingly important role in economic life. Knowledge Management-Oriented OA (Office Automation), whose connotation and extension have entirely changed, breaks through traditional limitations caused by Official Document-Oriented OA. Keeping an eye on the latest IT application technology, we will research the...
The Joint Task Force Global Network Operations (JTF-GNO) center is a subset of the Defense Information Systems Agency that is directly in charge of the security and architecture of the Department of Defense Global Information Grid. Since the inception of the JTF-GNO, the architecture has continually changed due to technical advances and increasing security concerns. Although many new systems have...
With the development of educational information, the major concerns of the university are how to manage the current dispersed information unitedly and how to realize seamless share between information systems. This paper studies using web services to implement service-oriented architecture, puts forward data share model frame based on web service and XML technology, introduces the achievements of...
ASIP is very suitable for the processing core of embedded systems, and the software technology of MDA, UML/XML provides security for its tools, the coupling between them will be the next technology feature. Moreover the design schema for ASIP MDA based UML/XML has been put forwarding in the paper.
This paper describes the results of the FP6 project SWIM-SUIT (System Wide Information Management -- Supported by Innovative Technologies) that currently integrates a number of existing ATM (Air Traffic Management) systems on top of a newly build prototype. As SWIM-SUIT has been identified to provide relevant inputs to SESAR, the authors give an overview on the prototype architecture and major software...
One of the key motivations of policy-based management is flexibility and adaptability to existing infrastructure and change management. In the context of security, modern policy languages such as XACML are extensible and support natively the expression of new information and manipulation operations. However, policy engines, which evaluate users' requests according to policies, may not support this...
The development of web 2.0 increases the call for agile and simple Business process support. SOA (Service oriented Architecture) provides companies with a new model to build their IT applications around their business processes and combine them dynamically and flexibly with the services of partner companies. In this open and distributed context, it is required to implement an appropriate security...
Data synchronization is an important issue which to be resolved in digital campus. This paper, according to the characteristic of Web Services technology, XML technology and SOA(Services Oriented Architecture), puts forward a solution based on Enterprise Service Bus(ESB). We have implemented data synchronization between HR System and LDAP, and verified that the program has a strong practical.
With the maturity of SOA and rapid development of Internet, a new type of software delivery mode named SaaS (Software as a Service) which provides the customers functionalities needed arises. It saves the cost of IT operation and suits to the small to medium firms very much. Ecommerce has grown extraordinarily nowadays with widespread Internet usage. In order to make trades more convenient and faster,...
Service-oriented Architecture (SOA) is increasingly relevant across several domains of application by promising systems openness and unification over a common design and communication paradigm. At device level, the application of SOA is carried, on one hand, by Devices Profile for Web Services (DPWS) and complementary web-based specifications oriented towards resource management, and, on the other...
Smart environment applications have gained a lot of attention and acceptance from the community. For this reason, many design and evaluation efforts target these applications. However, these applications rely on a software architecture that driven by a well-designed middleware. In this paper we propose design and evaluation requirements for smart environment software architectures and demonstrate...
Wireless sensor networks (WSNs) have many applications in home and industrial automation, and the management and integration of WSNs into Internet and IP-based networks is still getting tremendous interesting. This paper presents a micro SOA-model as part of a 4-layered, SOA-based architecture targeting resource-constrained devices with 48 KB of ROM and 10 KB of RAM. The key idea in this model is...
The geographical knowledge-informed digital gazetteer service (KIDGS) is a standard web service that provides unified XML-based access interfaces for various applications. In order to solve the problem of the raising data storage crabbed from millions of web pages and increasing query efficiency requirements for different levels of requests, we analyze the characteristics of cloud computing application...
Internet-based E-government has become a new work model of government departments. But due to heterogeneous and autonomous between different business systems, there are barriers in E-government systems when they are interoperating. To eliminate information silos, building a unified information-sharing platform is a necessary choice for the work of the government's information. This paper studies service-oriented...
This paper introduces an approach to realize service-oriented architecture (SOA) governance using a messaging network. The proposed solution uses a messaging network with a structured overlay. The messaging network is XML-based, and is an actual implementation of a content-based network. The proposed scheme provides a network-centric approach to ensure SOA governance by use of a common proactive scheme...
A large number of enterprises are turning to service-oriented architecture (SOA) for designing, using and managing their information technology (IT) systems. SOAP-based web services are the most commonly found services in today's SOA implementations. This paper reviews different possible classes of vulnerabilities in web services and investigates the advantages and shortcomings of available solutions...
Along with the further improvement of Chinese medical aid system in 21st century, the system interface and security has been in front us. Web services are being positioned as the technological solution framework for achieving this aggregation in the context of cross-organizational business applications through the Internet. In such a context, security is currently one of the main concerns and several...
Service oriented architecture (SOA) is currently the way to design and integrate information services in enterprises. SOA is usually based on Web services,originating from the e-business world, but SOA is not only technology, it is more of a philosophy. SOA has been selected as the architectural solution for the new command, control, communication, computers, information, intelligence, surveillance...
Service-oriented architecture provides flexible methods for systems development and integration. It is widely adopted in Web services. On the basis of studying service-oriented architecture and Web service security standards, this paper proposes a method for accessing trusted services based on service-oriented architecture and gives out a system implementation model.
The service-oriented architecture paradigm is influencing modern software systems remarkably and Web services are a common technology to implement such systems. However, the numerous Web service standard specifications and especially their ambiguity result in a high complexity which opens the door for security-critical mistakes.This paper aims on raising awareness of this issue while discussing a...
