Our contributions are two-fold as Horizon provides i) an API for accurately modeling processing time of discrete event simulation models by augmenting events with time spans and ii) a lightweight parallelization scheme that utilizes timing information to guide the parallel execution of simulations on multi-core computers. In this paper we primarily focus on the latter. horizon fileadmin/papers/2009/2009-kunz-mascots-horizon.pdf Poster Online IEEE Computer Society

Implementing or adapting the systems under test for such heterogeneous environments as network simulators, network emulators, testbeds, and end systems is immensely time and work intensive. In this paper, we present VIPE, a unified virtual platform for network experimentation, that slashes the porting effort. It allows to smoothly evolve a single implementation of a distributed system or protocol from its design up into its deployment by leveraging any form of network experimentation tool available. deployment, network experimentation, resource virtualization, simulation fileadmin/papers/2009/2009-landsiedel-visa-vipe.pdf Print ACM Press

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

It achieves these properties by introducing a new cryptographic namespace. This document specifies an extension for HIP that enables middleboxes to unambiguously verify the identities of hosts that communicate across them. This extension enables middleboxes to verify the liveness and freshness of a HIP association and, thus, enables reliable and secure access control in middleboxes.
