    Lightweight Integrity Protection for Web Storage-Driven Content Caching

    The term web storage summarizes a set of browser-based technologies that allow application-level persistent storage of key/values pairs on the client-side. These capabilities are frequently used for caching of markup or script code fragments, e.g., in scenarios with specific bandwidth or responsiveness requirements. Unfortunately, this paper is inherently insecure, as...

    The Lively PartsBin - A Cloud-Based Repository for Collaborative Development of Active Web Content

    The Lively Kernel is a browser-based environment for authoring active Web content. Being a self-supporting system, it is simple and compact, yet it supports rapid authoring with little need for programming expertise. Most importantly, the entire context of creation is now embedded in the cloud, a shared space in which...

    The State of the Cross-Domain Nation

    By deploying a configuration that allows the creation of client-side, cross-domain HTTP requests, a Web application weakens the same-origin policy. This enables sophisticated browser-based interaction which is not possible in the standard model, but also may lead to insecurities. In this paper, the authors briefly cover the technical background of...

    L1 - An Intermediate Language for Mixed-Protocol Secure Computation

    Secure Computation (SC) enables secure distributed computation of arbitrary functions of private inputs. It has many useful applications, e.g. benchmarking or auctions. Several general protocols for SC have been proposed and recently been implemented in a number of compilers and frameworks. These compilers or frameworks implement one general SC protocol...

    Practical Secure and Efficient Multiparty Linear Programming Based on Problem Transformation

    Cryptographic solutions to privacy-preserving multiparty linear programming are slow. This makes them unsuitable for many economically important applications, such as supply chain optimization, whose size exceeds their practically feasible input range. In this paper the authors present a privacy-preserving transformation that allows secure outsourcing of the linear program computation in...

    Plug-in Privacy for Smart Metering Billing

    Traditional electricity meters are replaced by Smart Meters in customers' households. Smart Meters collects fine-grained utility consumption pro les from customers, which in turn enables the introduction of dynamic, time-of-use tariffs. However, the ne-grained usage data that is compiled in this process also allows to infer the inhabitant's personal schedules...

    Towards Performance Prediction for Cloud Computing Environments Based on Goal-Oriented Measurements

    Scalability and performance are critical quality attributes of applications developed for the cloud. Many of these applications have to support hundreds or thousands of concurrent users with strongly fluctuating workloads. Existing approaches for software performance evaluation do not address the new challenges that arise for applications executed in cloud computing...

    Transactional Intent

    Data state in a data management system such as a database is the result of the transactions performed on that data management system. Approaches such as single-message transactions and field calls come closer than before/after values to expressing the intent of a transaction, the semantic transformation that should be performed...

    A Reference Architecture for Multi-Level SLA Management

    There is a global trend towards service-orientation, both for organizing business interactions but also in modern IT architectures. At the business-level, service industries are becoming the dominating sector in which solutions are flexibly composed out of networked services. At the IT level, the paradigms of Service-Oriented Architecture and Cloud Computing...

    5 From the Internet of Things to the Web of Things: Resource Oriented Architecture and Best Practices

    Creating networks of "Smart things" found in the physical world (e.g., with RFID, wireless sensor and actuator networks, embedded devices) on a large scale has become the goal of a variety of recent research activities. Rather than exposing real-world data and functionality through vertical system designs, the authors propose to...

    A Resource Oriented Architecture for the Web of Things

    Many efforts are centered around creating large-scale networks of "Smart things" found in the physical world (e.g., wireless sensor and actuator networks, embedded devices, tagged objects). Rather than exposing real-world data and functionality through proprietary and tightly-coupled systems, the authors propose to make them an integral part of the Web....

    Real-World Service Interaction With Enterprise Systems in Dynamic Manufacturing Environments

    The factory of the future will be heavily based on internet and web technologies. A new generation of devices with embedded hardware and software will feature greatly improved storage, computing, and networking capabilities. This will lead to a system landscape of millions of networked devices that is heterogeneous with respect...

    Using Cloud Standards for Interoperability of Cloud Frameworks

    Today's need for Open Frameworks, especially in the Cloud community, demands for standards. These standards are needed to ensure portability, interoperability and integration of Cloud sites. This technical paper describes how an emerging Cloud standard, the Open Cloud Computing Interface, can be used integrate two major Cloud Frameworks (SLA@SOI and...

    Sharing Using Social Networks in a Composable Web of Things

    In the emerging "Web of Things", digitally augmented everyday objects are seamlessly integrated to the Web by reusing Web patterns such as REST. This results in an ecosystem of real-world devices that can be reused and recombined to create new ad-hoc applications. This, however, implies that devices are available to...

    Design of a Web-Based Distributed Location-Aware Infrastructure for Mobile Devices

    Since GPS receivers have become a commodity anyone could access and use location information simply and freely. Such an easy access to ones' location is instrumental to development of location-aware applications. However, existing applications are static in that they do not model relations between places and mobile things. Moreover, these...

    Reliable Execution of Business Processes on Dynamic Networks of Service-Enabled Devices

    It is expected that future shop-floors will be populated by thousands of networked embedded devices. Those will not only communicate using IP (as in TCP/IP), but also feature some autonomy, allowing them to collaborate among themselves and with enterprise systems. As they can offer both their mechatronic and higher-level functions...
