Abstract: The paper presents a design and discusses configuration aspects of an overlay transport protocol based on an idea of the peer-to-peer direct and anonymous distribution overlay (P2PRIV). We estimate a secure configuration of the protocol and examine a correlation between the P2PRIV?s anonymous path lengths and latency. An increase of the path lengths speaks strongly in favor of the parallel solution?s anonymity, as in classical cascade networks. In the paper we evaluate the new protocol in a scope of a trade-off between anonymity and traffic performance and show that the presented solution allows effectively increasing anonymity with relatively low impact on anonymous transport latency.

2008-05-21: Nya modeller för kryptering gör datakommunikationen effektivare

Published: 2008-05-21

Om datainformation inte ska kunna avlyssnas av obehöriga måste den krypteras. Utmaningen för branschen idag är att göra krypteringen tillräckligt säker samtidigt som den bör vara snabb, billig och ta lite plats i t ex mobiltelefoner och andra begränsade miljöer. De senaste fem åren har de 15-20 främsta universiteten i Europa och lika många företag arbetat med att ta fram nya, effektivare kryptolösningar. Forskningen, som bedrivits inom ramen för ett EU-finansierat network of excellence har resulterat i att åtta nya s k strömchiffer valts ut, fyra för hårdvara och fyra för mjukvara.

30-5-2008: Professor Ernst Bonek: On MIMO Channel Models for LTE

Published: 2008-05-09

Professor Ernst Bonek, Honoris Causa, will give a seminar in conjunction with the conferment of the doctors' degree. The seminar is arranged by the Department for Electrical and Information Technology.

Title: On MIMO Channel Models for LTE
Location: E:1406 (E-huset LTH)
Time: 30th of May at 9.15

Abstract
========
Finally, 3gpp has given up their reluctance against MIMO. Plans now aim for a 4x4 MIMO to achieve an unprecedented 300 Mbit/s per cell. How to achieve such high data rates by spatial multiplexing in truly mobile scenarios, besides transmit diversity, does not seem to be finalized yet. One shortcoming, obvious to some but not to everyone in standardization, is the lack of MIMO channel models that accommodate moving users easily. To simulate the ensuing smoothly time-variant channel by non-deterministic, so-called stochastic channel models is not standard practice. I will present the work of my PhD Nicolai Czink, who developed exactly what is needed: a stochastic time-variant, frequency-selective, propagation-based MIMO channel model that is directly parameterized from measurements. The novel approach of this Random Cluster Model (RCM) is to describe the geometry of the channel completely by statistical cluster parameters. Clusters provide a compact way of describing the underlying propagation environment, without resorting to individual multipath components, thus reducing the number of parameters considrably. An essential innovation was an automatic clustering algorithm, allowing to process multi-gigabyte measurement data without user intervention. I will describe key features of the RCM and its validation by metrics like mutual information, Diversity Measure, and a new environmental characterization metric describing the compactness and directivity of the channel.

For more stationary channels, for which an exchange of channel-state information between transmitter and receiver in closed loop is easier, pre-determined MIMO matrices are under consideration. For these, I am glad to offer the Weichselberger model that captures the spatial structure of a MIMO channel by a particularly convenient way, the eigenmodes of the correlation matrix (see seminar at CCCD in Lund 2004).

The GNU radio - Summer internship at EIT, for two students

Published: 2008-04-11

At the department we will have a joint project between research groups to learn more about the GNU radio. With financial support from Communications Technology Lund (http://www.commtech.lth.se) we are now offering a summer internship for two students that want to study the technique more in detail, to program the device and set up a basic test link for data transmission and reception in the 2.4 GHz band.

GNU Radio, From Wikipedia:

GNU Radio is a free software toolkit for learning about, building, and deploying Software Defined Radios. Started in 1998, GNU Radio is now an official GNU project. GNU Radio is a signal processing package, which is distributed under the terms of the GNU General Public License. The goal is to give ordinary software people the ability to 'hack' the electromagnetic spectrum, that is, to understand the radio spectrum and think of clever ways to use it. As with all software-defined radio systems, reconfigurability is the key feature. Instead of purchasing multiple expensive radios, a single more generic radio is purchased, which feeds into powerful signal processing software (GNU Radio, in this case). Currently only a few forms of radio are duplicated in GNU Radio, but if one understands the math of a radio transmission system, one can reconfigure GNU Radio to receive it.

The GNU Radio project created the Universal Software Radio Peripheral (USRP, [1]) which is a digital acquisition (DAQ) system containing four 64 mega sample-per-second (MS/s) 12-bit analog-to-digital (A to D) converters, four 128 MS/s 14-bit digital-to-analog (D to A) converters, and support circuitry including a high-speed USB 2.0 interface. The USRP is capable of processing signals up to 16 MHz wide. Several transmitter and receiver plug-in daughter boards are available covering various bands between 0 and 2.9 GHz [2]. The USRP was developed by Matt Ettus. For further information, see e.g.

Conditions
==========

The internship has a duration of 2-3 months (to be decided together with the students) and the department offers a monthly stipend of 8000 kr /student. It is suitable for two students that has some programming experience and with knowledge within radio and digital communication. Prior hardware experience is also qualifying.

Interested?

If you would like to know more about the internship contact Fredrik Tufvesson (office E:2371, email: fredrik.tufvesson@eit.lth.se). Technical details can be answered by Johan Löfgren (office E:2335, email: johan.lofgren@eit.lth.se) who will supervise the project together with Peter Hammarberg (email: peter.hammarberg@eit.lth.se) and Martin Hell (email: martin.hell@eit.lth.se) Applications, including a cover letter saying why you are interested and qualified for the internship, a course list with grades from both your Master’s degree and Bachelor degree and a CV should be sent to Fredrik Tufvesson, (office E:2371, email: fredrik.tufvesson@eit.lth.se), no later than April 22, 2008.
