Web Services are the server side procedures provided to the web clients and web programmers to improve the application environment. When the service search is performed respective to particular keyword, there exists number of possible web service with almost same functionality. In such case, the comparative analysis is required in terms of availability, response time and security features of a ...

Web applications that require higher levels of security have various security options that can be deployed on the server. However providing security on the client consuming the service remains a challenge especially when the application runs in a web browser. While various types of security hardware can work with the user's computer, there is no convenient way for web applications to access suc...

In this paper we propose a security architecture and mechanism for Virtual Organizations (VO) for businesses. The VOs we consider are based on web service technology to address interoperability issues and cater for future business software, and are dynamic, i.e. their membership may change frequently throughout their lifetime. We improve over previous approaches in the following aspect: We have...

SOA and Web Services technologies have been increasingly applied to network centric C2. In this paper, a service‐oriented C2 software architecture is firstly proposed based on SOA ideas and Web services technology to provide framework and guidance to service integration in future service‐oriented C2 systems, in which software and capability of C2 systems often are wrapped web serv...

To distinguish between human user and computer program to enhance security, a popular test called CAPTCHA is used on Web. CAPTCHA has an important role in preventing Denial Of Service (DOS) attacks in computer networks. There are many different types of CAPTCHA in different languages. Due to the expansion of Persian-language and documents on internet, creating a suitable Persian CAPTCHA seems t...

THIS special issue presents recent research results in a field of research that is itself rather new. When Service Oriented Architectures (SOA) came of age, no specific security technology for web services was available and transport protocols security mechanisms were used instead. For instance, web services message confidentiality was achieved using transport security protocols like SSL and HT...

A significant web security issue facing Internet users and organizations is the securing of web content against unauthorised tampering. Users must be comfortable with the security offered by web applications that sensitive web-based services. Some progress has been made in addressing the verification of web server content integrity, but current solutions are restricted by the limitations of the...

The adoption of a policy-based approach for the dynamic regulation of a system or service (e.g. security, QoS or mobility service) requires an appropriate policy representation and processing. In the context of the Semantic Web, the representation power of languages enriched with semantics (i.e. semantic languages), together with the availability of suitable interpreters, make such kind of lang...

Purpose – This survey aims to study and analyze current techniques and methods for context-aware web service systems, to discuss future trends and propose further steps on making web services systems context-aware. Design/methodology/approach – The paper analyzes and compares existing context-aware web service-based systems based on techniques they support, such as context information modeling,...

Lately, XML Web Services are emerging as a dominant platform in the computing world. At the moment, the web has evolved into an active medium for providers and consumers of services. One of the major problems for XML Web Services is the related with security. The paper describes a comprehensive XML Web Services Management Architecture that supports, integrates and unifies several security model...
