Security enhancement for a dynamic ID-based remote user authentication scheme

Abstract: In a paper recently published in the IEEE transaction on consumer electronics, Das, Saxena, and Gulati proposed a dynamic ID-based remote user authentication scheme using smart cards that allows the users to choose and change their passwords freely, and does not maintain any verifier table. It can protect against ID-theft, replaying, forgery, guessing, insider, and stolen verifier attacks. However, this paper shows that Das, Saxena, and Gulati's scheme has some attacks. Therefore, we propose a slight modification to their scheme to improve their weaknesses. As a result, the improved scheme can enhance the security of Das, Saxena, and Gulati's scheme. In addition, the proposed scheme does not add many computational costs additionally. Compare with their scheme, our scheme is also efficient.

Dynamic selection of Web services with recommendation system

Abstract: The realization of the semantic Web is underway with the development of an arena of services providing similar properties, capabilities, interfaces, and effects. To pick one of such similar services that matches the user's requirements is a difficult task and necessitates the use of an intelligent decision making framework. This paper addresses precisely this component. We present the design of a dynamic Web service selection framework that makes use of a semantic matcher to support matching and composition of software services. The framework also uses a recommendation system which helps a user to select the best service that matches his requirements. This recommendation system results in evolution of the framework to dynamically adapt to users requirements.

Efficient runtime service discovery and consumption with hyperlinked RESTdesc

Abstract: Hyperlinks and forms let humans navigate with ease through websites they have never seen before. In contrast, automated agents can only perform preprogrammed actions on Web services, reducing their generality and restricting their usefulness to a specialized domain. Many of the employed services call themselves RESTful, although they neglect the hypermedia constraint as defined by Roy T. Fielding, stating that the application state should be driven by hypertext. This lack of link usage on the Web of services severely limits agents in what they can do, while connectedness forms a primary feature of the human Web. An urgent need for more intelligent agents becomes apparent, and in this paper, we demonstrate how the conjunction of functional service descriptions and hypermedia links leads to advanced, interactive agent behavior. We propose a new mode for our previously introduced semantic service description format RESTdesc, providing the mechanisms for agents to consume Web services based on links, similar to human browsing strategies. We illustrate the potential of these descriptions by a use case that shows the enhanced capabilities they offer to automated agents, and explain how this is vital for the future Web.

Enhancing Web Service Selection by User Preferences of Non-functional Features

Abstract: Selection of an appropriate Web service for a particular task has become a difficult challenge due to the increasing number of Web services offering similar functionalities. The functional properties describe what the service can do and the non-functional properties depict how the service can do it. Non-functional properties involving qualitative or quantitative features have become essential criteria to enhance the selection process of services making the selection process more complicated. Chaari et al. [8] proposed an ontological framework for modeling and exploiting non-functional properties. In this paper, we propose a simple Web services selection scheme based on userpsilas requirement of the various non-functional properties and interaction with the system. The proposed framework utilizes user preferences as an additional input to the selection engine and the system ranks the available services based on the requirement. The method is validated using a popular Web services bench mark and the experiment results indicate that the scheme is useful and warrants further research.

QoS Based Ranking for Web Services: Fuzzy Approaches

Abstract: Web service selection is one of important steps in many Web service applications such as Web service composition systems and UDDI registries. As more and more Web services are available on the Internet, there are often a number of Web services which are functionally matched with a service request. QoS plays a crucial role in selecting Web services in terms of their quality. According to userpsilas requirements on service quality, candidate Web services are ranked in order to find best Web services. In many cases, the value of a QoS property may be difficult to be precisely defined. Therefore fuzzy logic can be applied to support for representing imprecise QoS constraints. In addition, suitable ranking algorithms which can deal with fuzzy numbers have been proposed. In this paper, we will present an overview of current research works which concentrate on developing QoS based ranking algorithms by basing on fuzzy logic. These works are summarized and compared in order to assess their benefits and limitations. Such analysis contributes in developing more complete solutions in ongoing works in the field of Web service discovery and selection.
