    NEMESYS: Enhanced Network Security for Seamless Service Provisioning in the Smart Mobile Ecosystem

    As a consequence of the growing popularity of smart mobile devices, mobile malware is clearly on the rise, with attackers targeting valuable user information and exploiting vulnerabilities of the mobile ecosystems. With the emergence of large-scale mobile botnets, Smartphones can also be used to launch attacks on mobile networks. The...

    Framework for Evaluating Collaborative Intrusion Detection Systems

    IT infrastructures permeate user's daily lives, and their society becomes more dependent on information technologies [Cas05]. Cost reduction, improved business opportunities or quality of services; everyday more systems get connected to the Internet. As the scale of such interconnected IT infrastructures grows, due to short innovation cycles, information and communication...

    Toward Cell Outage Detection With Composite Hypothesis Testing

    This paper presents a novel cell outage detection algorithm based on statistics and performance metrics, which enables a Base Station (BS) to detect a failure/outage of a neighbor cell. The algorithm is a weighted combination of three hypothesis tests based on: the distribution of the Channel Quality Indicator (CQI), the...

    Distributed Lifetime Maximisation in Wireless Sensor Networks Using Cooperation Techniques

    This paper is concerned with the lifetime maximisation of Wireless Sensor Networks (WSNs) in the context of slow-fading communication channels. The problem is first formulated as a decomposable convex optimisation problem. Dual decomposition is presented as a way to decompose the problem into smaller sub-problems that can be solved locally...

    SEIP: Simple and Efficient Integrity Protection for Open Mobile Platforms

    SEIP is a simple and efficient but yet effective solution for the integrity protection of real-world cellular phone platforms, which is motivated by the disadvantages of applying traditional integrity models on these performance and user experience constrained devices. The major security objective of SEIP is to protect trusted services and...

    DR@FT: Efficient Remote Attestation Framework for Dynamic Systems

    Remote attestation is an important mechanism to provide the trustworthiness proof of a computing system by verifying its integrity. In this paper, the authors propose an innovative remote attestation framework called DR@FT for efficiently measuring a target system based on an information flow-based integrity model. With this model, the high...

    On the Relation of MIMO APP Detection and SIMO Maximum Ratio Combining

    In classical non-iterative MIMO detection a soft-output MIMO detector computes likelihoods of the transmit bits being 1 or 0, given the received symbol vector. In iterative MIMO detection-decoding, detection performance is improved by exploiting apriori information about bit probabilities from the decoder. Transmit bits are viewed as random variables and...

    Distributed Exchange of Alerts for the Detection of Coordinated Attacks

    Attacks and intrusions to information systems cause large revenue losses. The prevention of these attacks is not always possible by just considering information from isolated sources of the network. A global view of the whole system is necessary to react against the different actions of such an attack. The design...
