This identifier-locator split introduces anew identifier between human readable domain names and routable IPaddresses. Mapping between identifiers and locators requires additionalname mapping mechanisms because their relation is not trivial. Despite itspopularity and efficiency, the DNS system is not a perfect choice forperforming this mapping because identifiers are not hierarchicallystructured and mappings are frequently updated by users. In this paper wediscuss the features needed to resolve flat identifiers to locators in asecure manner. In particular, we focus on the features and the performancethat identifier-locator split protocols require from a mapping system. Tothis end, we consider a mapping system for an identifier-locator splitbased mobility solution and evaluate its performance.

Although the security needs are well-recognized in this domain, it is still not fully understood how existing IP security protocols and architectures can be deployed. In this paper, we discuss the applicability and limitations of existing Internet protocols and security architectures in the context of the Internet of Things. First, we give an overview of the deployment model and general security needs. We then present challenges and requirements for IP-based security solutions and highlight specific technical limitations of standard IP security protocols. iotsec fileadmin/papers/2011/2011-heer-iot-challenges.pdf Online Springer

These techniques are applicable in wireless networks as well, however, only under certain limiting conditions. The authors present a generic overlay that caters to the special requirements of providing and discovering services in wireless mesh networks. The focus of the approach lies on maintaining scalability in large-scale dynamic networks as well as routing efficiency with regard to the communication characteristics of the underlying network.

For municipalities, it is often challenging to achieve the bandwidth and coverage that is necessary for many of the envisioned network services. At the same time, Wi-Fi-sharing communities achieve high bandwidth and good coverage at a very low cost by capitalizing on the dense deployment of private access points in urban areas. However, from a technical, conceptual, and security perspective, Wi-Fi sharing community networks resemble a patchwork of heterogeneous networks instead of one well-planned city-wide network. This patchwork character stands in stark contrast to a uniform, secure platform for public and commercial services desirable for the economic success of such a network. Hence, despite its cost-efficiency, the community-based approach cannot be adopted by municipalities easily. In this paper, we show how to realize municipal wireless services on top of a Wi-Fi-sharing infrastructure in a technically sound and economically attractive fashion. In particular, we focus on how to securely provide services to mobile clients with and without client-side software support. Our solution cleanly separates the roles of controlling and administering the network from providing bandwidth and wireless access. With this separation, commercial ISPs and citizens with their private Wi-Fi can contribute to the network infrastructure. This allows municipalities in turn to focus their resources on municipal wireless services. mobile_access http://www.comsys.rwth-aachen.de/fileadmin/papers/2010/2010-heer-icc-pisa-sa.pdf Print IEEE Press

The goals of these networks are to bridge the digital divide, stimulate innovation, support economic growth, and increase city operations efficiency. While establishing such urban networks is financially challenging for municipalities, Wi-Fi-sharing communities accomplish good coverage and ubiquitous Internet access by capitalizing on the dense deployment of private access points in urban residential areas. By combining Wi-Fi communities and municipal Wi-Fi, a collaborative municipal Wi-Fi system promises cheap and ubiquitous access to mobile city services. However, the differences in intent, philosophy, and technical realization between community and municipal Wi-Fi networks prevent a straight-forward combination of both approaches. In this paper, we highlight the conceptual and technical challenges that need to be solved to create collaborative municipal Wi-Fi networks. mobile_access http://www.comsys.rwth-aachen.de/fileadmin/papers/2010/2010-heer-percomws-collaborative-municipal-wi-fi.pdf Print IEEE Press

However, communication is typically performed with a static set of protocols selected at design time based on simplified assumptions ignoring the environment's heterogeneity. In this paper, we argue that protocols can be orchestrated as software components driven purely by their functionality and the demands of the execution environment. Our end-system protocol framework Adapt bases on extensible ontological models that semantically describe protocol and environment properties. At runtime, each connection receives a custom-tailored protocol stack that Adapt orchestrates from the requirements derived from the application, user, and environment. With this approach, end-systems can reason about the functionality and quality of automatically composed and adapted protocol compounds while remaining open to existing and future protocols. https://www.comsys.rwth-aachen.de/fileadmin/papers/2009/2009-goetz-mobiarch-protocol-orchestration.pdf print Krzysztof Zielinski and Adam Wolisz and Jason Flinn and Anthony LaMarca ACM

They also inspect and filter traffic, detect network intrusion, control access to network resources, and enforce different levels of quality of service. The cornerstones for these security-related network services are end-host authentication and authorization. Using a cryptographic namespace for end-hosts simplifies these tasks since it gives them an explicit and verifiable identity. The Host Identity Protocol (HIP) is a key-exchange protocol that introduces such a cryptographic namespace for secure end-to-end communication. Although HIP was designed with middleboxes in mind, these cannot securely use its namespace because the on-path identity verification is susceptible to replay attacks. Moreover, the binding between HIP as an authentication protocol and IPsec as payload transport is insufficient because on-path middleboxes cannot securely map payload packets to a HIP association. In this paper, we propose to prevent replays attack by treating packet-forwarding middleboxes as first-class citizens that directly interact with end-hosts. Also we propose a method for strengthening the binding between the HIP authentication process and its payload channel with hash-chain-based authorization tokens for IPsec. Our solution allows on-path middleboxes to efficiently leverage cryptographic end-host identities and integrates cleanly into existing protocol standards. mobile_access http://www.comsys.rwth-aachen.de/fileadmin/papers/2009/2009-heer-icc-end-host-authentication.pdf Print Piscataway, NJ, USA

The typical static classification into network layers or class hierarchies cannot appropriately accommodate cross-cutting changes such as overlay routing or cross-layer signaling. In this paper, we discuss how protocol composition can be driven by functionality and demand at runtime based on extensible semantic models of protocols and their execution environment. Such an approach allows to reason about the functionality and quality of automatically composed and adapted protocol compounds and it is open to existing and future protocols. https://www.comsys.rwth-aachen.de/fileadmin/papers/2008/2008-goetz-mobiarch-adapt.pdf Print Karin Anna Hummel and James P.

To leverage this coverage, sharing of access points as Internet uplinks among users has first become popular in communities of individuals and has recently been adopted as a business model by several companies. However, existing implementations and proposals suffer from the security risks of directly providing Internet access to strangers. In this paper, we present the P2P Wi-Fi Internet Sharing Architecture PISA, which eliminates these risks by introducing secure tunneling, cryptographic identities, and certificates as primary security concepts. Thus, PISA offers nomadic users the same security that they expect from a wired Internet connection at home. Based on its three fundamental mechanisms, PISA achieves a flexibility which opens significant advantages over existing systems. They include user mobility, anonymity, service levels with different performance and availability characteristics, and different revenue models for operators. With this combination of key features, PISA forms an essential basis for global, seamless, and secure Wi-Fi sharing for large communities. mobile_access http://www.comsys.rwth-aachen.de/fileadmin/papers/2008/2008-heer-ict-secure-wifi.pdf Print IEEE

Until now, the simulation in charge of representing the network has been required to be real-time capable, as otherwise a time drift between the simulation and the real network devices may occur and corrupt the results. In this paper, we present our work on synchronized network emulation. By adding a central synchronization entity and by virtualizing real systems for means of control, we can build-up network emulations which contain both unmodified x86 systems and network simulations of any complexity.

However, node mobility and the continually changing physical topology pose a special challenge to scalability and the design of a DHT for mobile ad-hoc networks. In this paper, we show that with some local knowledge we can build a scalable and mobile structured peer-to-peer network, called Mobile Hash Table (MHT). Furthermore, we discuss practical challenges such as Churn, load balacing and security of the Mobile Hash Table.

Due to their crucial characteristics – namely scalability, flexibility, and resilience – they are quite interesting for being applied in ad-hoc networks. But, there are plenty of open questions concerning the applicability of Distributed Hash Tables in mobile ad-hoc scenarios: Do new problems arise when both technologies are used together? Are there any synergy effects when both technologies are combined? Are the results and assumptions, made for the infrastructural Internet, still true if a mobile ad-hoc network is used instead?
