    Versatile Key Management for Secure Cloud Storage

    Not only does storing data in the cloud utilize specialized infrastructures facilitating immense scalability and high availability, but it also offers a convenient way to share any information with user-defined third-parties. However, storing data on the infrastructure of commercial third party providers, demands trust and confidence. Simple approaches, like merely...

    A Legal and Technical Perspective on Secure Cloud Storage

    Public cloud infrastructures represent alluring storage platforms supporting easy and flexible, location-independent access to the hosted information without any hassle for maintaining own infrastructures. Already widely established and utilized by end-users as well as by institutions, the hosting of data on untrusted platforms, containing private and confidential information, generates concerns...

    A Secure Cloud Gateway based upon XML and Web Services

    Storing data in the cloud offers a scalable and easy way to handle large amounts of data guaranteeing availability and scalability by the hosting cloud service providers. The price for the gained availability is uncertainness about the integrity and confidentiality of the data. Even if common approaches provide high availability...

    Questioning Flooding as a Routing Benchmark in Opportunistic Networks

    Routing in opportunistic networks, as a relatively young discipline, still lacks coherent, simple and valid benchmarks. It is customary to use epidemic routing as performance benchmark for opportunistic networks. The authors describe the current simulation practices that do not expose the shortcomings of flooding as an upper bound. In this...

    Recovering Grammar Relationships for the Java Language Specification

    Grammar convergence is a method that helps discovering relationships between different grammars of the same language or different language versions. The key element of the method is the operational, transformation-based representation of those relationships. Given input grammars for convergence, they are transformed until they are structurally equal. The transformations are...

    Routing With Metric-Based Topology Investigation

    As routing takes place in an entirely distributed system where local routers have no direct access to globally consistent network state information, a routing algorithm has to make uncertain forwarding decisions. As the network state may change, due to failures or new adoptions of net-works, routing algorithms have to adapt...

    Reverse Engineering Grammar Relationships

    Many software languages (and programming languages, in particular) are described simultaneously by multiple grammars that are found in different software artifacts. For instance, one grammar may reside in a language specification; another grammar may be encoded in a parser specification; yet another grammar may be present in an XML schema...

    Integrating Business Process And User Interface Models Using A Model-Driven Approach

    Business services are complex entities that encompass descriptions about different aspects including business processes and user interfaces. Typically, the modeling of business services results on several correlated models. On the one hand, there is the need to keep these models apart in order to attain the levels of abstractions needed...

    Using Ontologies With UML Class-Based Modeling: The TwoUse Approach

    UML class-based models and OWL ontologies constitute modeling approaches with different strength and weaknesses that make them appropriate for specifying different aspects of software systems. The paper proposes an integrated use of both modeling approaches in a coherent framework - TwoUse. The paper presents a framework involving different concrete syntaxes...
