technical basis of the Internet. How shouldthe Internet be developed to deal with the newrequirements deal? And how is the networkof the future? To these questions, scientistsfrom academia and industry met on 17.7.2008 inKarlsruhe Castle (Fig. 2). Under the title ’1stWorkshop on Architectures, Services and Appli-cations for the Next Generation Internet’, ap-proaches to support mobility, quality of service,and advanced services using peer-to-peer tech-nologies were discussed. The conference is partof the project ’Spontaneous Virtual Networks’(SpoVNet). In this project researchers from theUniversities of Karlsruhe, Mannheim, Stuttgart,and Tuebingen work together. SpoVNet’s goalis to develop solutions for current and futurenetworked systems. The ideas developed in theproject make both a contribution to the devel-opment of the Internet, furthermore, they candirectly incorporate new products. SpoVNetis one of the projects in the information tech-nology support program Baden-Wuerttemberg(BW-FIT) of the country Baden-Wuerttembergand a total of 2.3 million euros. From 38 ap-plications SpoVNet was as one of five ’excellentprojects’ by an international commission of ex-perts.http://www.spovnet.de17.07.2008 Christoph Mayer [email protected]

ITM staff day 2008
The annual ITM staff day in this year featured aboat ride, playing boule and a barbecue. Start-ing from Ruppur we canoed to Muhlburg. In theafternoon we rode by bike to Blankenloch werewe had a nice barbecue and an introduction intoplaying boule. We finished the day with a bouletournament. We all enjoyed the perfect staff dayweather and had a lot of fun.16.07.2008 Jochen Furthmuller [email protected]

In-network data aggregation allows energy-efficient communication within a sensor network.However, such data aggregation introduces newsecurity challenges. As sensor nodes are prone tonode-compromise, a fraction of nodes might actmaliciously and forge aggregated data. For ar-bitrary aggregation functions, the verification ofauthenticity of aggregated data, i.e., its correct-ness, integrity, and origin, is impossible. Thus,one can either aggregate data and save energyor verify authenticity, not both. We present“ESAWN”, a protocol that probabilistically re-laxes authenticity in the presence of a fractionof compromised nodes. This enables a trade-off between probabilistic authenticity and proba-bilistic, energy-saving data aggregation. Besidestheoretical analysis, we present MICA2-basedsimulation results. They indicate that even forhigh probabilities of authenticity and fractionof compromised nodes, ESAWN is more energy-efficient compared to secure but non-aggregatingcommunication. For example, with 20% com-promised nodes and 90% authenticity, ESAWNsaves up to 40% energy.

Christian Hubsch: Considering NetworkHeterogeneity in Global Application LayerMulticast Provision. In EuroView, July 2008.
As an alternative approach to the non-yetwidely available IP Multicast, ApplicationLayer Multicast (ALM) has recently becomesubject of intense research. Running on top ofexisting transport layers, most proposed ALMprotocols assume homogeneous underlays, nottaking into account the continuing availabilityof more and more different access technologieslike e. g., DSL, cell-based mobile networks and(wireless) local area networks. Also, techniquesnot yet available globally (quality of service

support, IP Multicast, ...) may be employedin parts of the Internet by certain ISPs. Wepresent an approach that enhances a specificALM protocol by considering several factorsconcerning attributes of member nodes’ under-lay specifications as well as their capacities andproperties, configurable through the employedapplication that uses the protocol for datadissemination. The ALM protocol is part of theFuture Internetarchitecture SpoVNet.http://doc.tm.uka.de/2008/42-abstract-huebsch.pdfhttp://doc.tm.uka.de/2008/42-presentation-huebsch.pdf (slides)
Christoph P. Mayer, Thomas Gamer andMartina Zitterbart: Towards Understand-ing the Global Behavior of DDoS Attacks - AFramework for Distributed Attack Detectionand Beyond, August 2008. Presentation atEURECOM Security Research Seminar.
Distributed Denial-of-Service attacks poseunpredictable threats to the Internet infrastruc-ture and Internet-based business. Therefore,many attack detection systems and anomalydetection methods were developed in the past.The development and implementation of suchmethods is challenging and time consuming.Furthermore, a realistic evaluation of thesemechanisms and comparable results are impos-sible up to now. Therefore, we developed theDistack framework for attack detection whichallows an easy integration of various detectionmethods as lightweight modules. These modulescan be combined easily and arbitrarily, andtherefore allow for high flexibility. Additionally,our framework can be applied in differentruntime environments transparently. This en-ables an easy evaluation with meaningful andcomparable results based on realistic large-scalescenarios, e. g. by using a network simulator.This talk gives an overview of the Distackframework and the simulation toolkit we devel-oped for giving a base on the way towards aglobal understanding of DDoS attacks.http://doc.tm.uka.de/2008/MaGaZit Eurecom2008.pdf (slides)

The incremental adoption of IPv6, middleboxes (e.g., NATs, Firewalls) as well as com-pletely new network types and protocols plot apossible future of the Internet: Manifold net-works (e.g. IPv4, IPv6, Industrial Ethernet, sen-sor networks), which are not supposed or ableto communicate directly. To allow communica-tion between these networks, relays — deviceslocated in multiple networks that behave likegateways — are required. These relays trans-late between multiple network domains (e.g.,IPv4/IPv6 domain) and provide the necessaryend-to-end connectivity. In this scenario it islikely that a message has to traverse multipledomains. To find a relay path to another deviceand allow end-to-end communication, the follow-ing issues need to be addressed: (1) detectionof domain borders, (2) finding appropriate relaypaths, (3) managing relays. We propose a solu-tion towards these problems for the SpontaneousVirtual Networks Project (SpoVNet) based onvirtual coordinates.
