The Web has become an indispensable prerequisite of everyday live and the Web browser is the most used application on a variety of distinct devices. The content delivered by the Web has changed drastically from static pages to media-rich and interactive Web applications offering nearly the same functionality as native applications, a trend which is further pushed by the Cloud and more specifically the Cloud’s SaaS layer. In the light of this development, security and performance of Web browsing has become a crucial issue.
The usage of link quality based routing metrics significantly improves the quality of the chosen paths and by that the performance of the network. But, attackers may try to exploit link qualities for their purposes. Especially in tactical multi-hop networks, routing may fall prey to an attacker. Such routing attacks are a serious threat to communication. TOGBAD is a centralised approach, using topology graphs to detect routing attacks. In this paper, we enhance TOGBAD with the capability to detect fake link qualities. We use a Challenge/Response method to estimate the link qualities in the network. Based on this, we perform plausibility checks for the link qualities propagated by the nodes in the network. Furthermore, we study the impact of attackers propagating fake link qualities and present simulation results showing TOGBAD's detection rate.
This paper addresses special skills, learners in Internet-based learning scenarios need. In self-directed learning scenarios, as most Internet-based learning scenarios are designed, learners bear the responsibility for their learning progress. To ease this task, institutions could prime the learners for the situation which may be quite different to their previous learning experiences. Basing on a Delphi-study, conducted with experts from the e-Learning sector in Germany, Austria, and Switzerland, the basic requirements have been determined.
This paper picks up on one of the ways reported in the literature to represent hybrid models of engineering systems by bond graphs with static causalities. The representation of a switching device by means of a modulated transformer (MTF) controlled by a Boolean variable in conjunction with a resistor has been used so far to build a model for simulation. In this paper, it is shown that it can also constitute an approach to bond graph based quantitative fault detection and isolation in hybrid system models. Advantages are that Analytical Redundancy Relations (ARRs) do not need to be derived again after a switch state has changed. ARRs obtained from the bond graph are valid for all system modes. Furthermore, no adaption of the standard sequential causality assignment procedure (SCAP) with respect to fault detection and isolation (FDI) is needed.
The smart home of the future is typically researched in lab settings or apartments that have been built from scratch. However, comparing the lifecycle of buildings and information technology, it is evident that modernization strategies and technologies are needed to empower residents to modify and extend their homes to make it smarter. In this paper, we describe a case study about the deployment, adaption to and adoption of tailorable home energy management systems in 7 private households. Based on this experience, we want to discuss how hardware and software technologies should be designed so that people could build their own smart home with a high usability and user experience.
