Forschungsberichte der Fakultät IV – Elektrotechnik und Informatik Countering SMS Attacks: Filter Recommendations
نویسندگان
چکیده
In this paper we summarize the findings of our investigation on security issues of Short Message Service (SMS) clients on mobile phones. We realized that firmware updates will not be available on a large scale and thus see filtering of SMS traffic as the only possible counter measure against large scale attacks based on SMS messages. This paper presents our ideas on filtering SMS features by the mobile network operators.

Forschungsberichte der Fakultät IV – Elektrotechnik und Informatik Model Transformation of Model Fragments Using Borrowed Context: Extended Version
In this technical report we study the transformation of models in the context of algebraic graph transformation and triple graph grammars. The new contribution of the report is to define and analyze the transformation of model fragments in general and the propagtion of graph constraints in particular. With the borrowed context we developed a technique further to the model transformation with tr...
متن کاملForschungsberichte der Fakultät IV – Elektrotechnik und Informatik A Multi-Class Support Vector Machine Based on Scatter Criteria
We re-visit Support Vector Machines (SVMs) and provide a novel interpretation thereof in terms of weighted class means and scatter theory. The gained theoretical insight can be translated into a highly efficient extension to multi-class SVMs: mScatter-SVMs. Numerical simulations reveal that more than an order of magnitude speed-up can be gained while the classification performance remains large...
متن کاملForschungsberichte der Fakultät IV – Elektrotechnik und Informatik Revisiting Content Availability in Distributed Online Social Networks
Online Social Networks (OSN) are among the most popular applications in today’s Internet. Decentralized online social networks (DOSNs), a special class of OSNs, promise better privacy and autonomy than traditional centralized OSNs. However, ensuring availability of content when the content owner is not online remains a major challenge. In this paper, we rely on the structure of the social graph...
متن کاملForschungsberichte der Fakultät IV – Elektrotechnik und Informatik Conformance Analysis of Organizational Models in a new Enterprise Modeling Framework using Algebraic Graph Transformation - Extended Version
Organizational models play a key role in today's enterprise modeling. These models often show up as partial models produced by people with di erent conceptual understandings in a usually decentralized organization, where they are modeled in a distributed and non-synchronized fashion. For this reason, there is a rst major need to organize partial organizational models within a suitable modeling ...
متن کاملForschungsberichte der Fakultät IV – Elektrotechnik und Informatik Efficient Analysis and Execution of Correct and Complete Model Transformations Based on Triple Graph Grammars -Extended Version
Triple Graph Grammars are a well-established, formal and intuitive concept for the speci cation and analysis of bidirectional model transformations. In previous work we have formalized and analyzed already termination, correctness, completeness, local con uence and functional behaviour. In this paper, we show how to improve the e ciency of the execution and analysis of model transformations in ...
