Securing ad hoc networks

by Lidong Zhou, Zygmunt J. Haas
"... Ad hoc networks are a new wireless networking paradigm for mobile hosts. Unlike traditional mobile wireless networks, ad hoc networks do not rely on any fixed infrastructure. Instead, hosts rely on each other to keep the network connected. The military tactical and other security-sensitive operation ..."

nodes — to defend routing against denial of service attacks. We also use replication and new cryptographic schemes, such as threshold cryptography, to build a highly secure and highly available key management service, which forms the core of our security framework.

Decentralized Trust Management

by Matt Blaze, Joan Feigenbaum, Jack Lacy - In Proceedings of the 1996 IEEE Symposium on Security and Privacy , 1996
"... We identify the trust management problem as a distinct and important component of security in network services. Aspects of the trust management problem include formulating security policies and security credentials, determining whether particular sets of credentials satisfy the relevant policies, an ..."

A Secure Routing Protocol for Ad Hoc Networks

by Kimaya Sanzgiri, Bridget Dahill, Brian Neil Levine, Clay Shields, Elizabeth M. Belding-Royer , 2002
"... Most recent ad hoc network research has focused on providing routing services without considering security. In this paper, we detail security threats against ad hoc routing protocols, specifically examining AODV and DSR. In light of these threats, we identify three different environments with distin ..."

with distinct security requirements. We propose a solution to one, the managed-open scenario where no network infrastructure is pre-deployed, but a small amount of prior security coordination is expected. Our protocol, ARAN, is based on certificates and successfully defeats all identified attacks.

Secure Group Communications Using Key Graphs

by Chung Kei Wong, Mohamed Gouda , Simon S. Lam - SIGCOMM '98 , 1998
"... Many emerging applications (e.g., teleconference, real-time information services, pay per view, distributed interactive simulation, and collaborative work) are based upon a group communications model, i.e., they require packet delivery from one or more authorized senders to a very large number of au ..."

management. We formalize the notion of a secure group as a triple (U; K;R) where U denotes a set of users, K a set of keys held by the users, and R a user-key relation. We then introduce key graphs to specify secure groups. For a special class of key graphs, we present three strategies for securely

A Key-Management Scheme for Distributed Sensor Networks

by Laurent Eschenauer, Virgil D. Gligor - In Proceedings of the 9th ACM Conference on Computer and Communications Security , 2002
"... Distributed Sensor Networks (DSNs) are ad-hoc mobile networks that include sensor nodes with limited computation and communication capabilities. DSNs are dynamic in the sense that they allow addition and deletion of sensor nodes after deployment to grow the network or replace failing and unreliable ..."

key-management scheme designed to satisfy both operational and security requirements of DSNs.

Exokernel: An Operating System Architecture for Application-Level Resource Management

by Dawson R. Engler, M. Frans Kaashoek, James O’toole , 1995
"... We describe an operating system architecture that securely multiplexes machine resources while permitting an unprecedented degree of application-specific customization of traditional operating system abstractions. By abstracting physical hardware resources, traditional operating systems have signifi ..."

The Ponder Policy Specification Language

by Nicodemos Damianou , Naranker Dulay , Emil Lupu , Morris Sloman - LECTURE NOTES IN COMPUTER SCIENCE , 2001
"... The Ponder language provides a common means of specifying security policies that map onto various access control implementation mechanisms for firewalls, operating systems, databases and Java. It supports obligation policies that are event triggered conditionaction rules for policy based management ..."

Establishing Pairwise Keys in Distributed Sensor Networks

by Donggang Liu, Peng Ning , 2003
"... Pairwise key establishment is a fundamental security service in sensor networks; it enables sensor nodes to communicate securely with each other using cryptographic techniques. However, due to the resource constraints on sensors, it is infeasible to use traditional key management techniques such as ..."

LEAP: Efficient Security Mechanisms for Large-scale Distributed Sensor Networks

by Sencun Zhu , 2003

Protocol), a key management protocol for sensor networks that is designed to support in-network processing, while at the same time restricting the security impact of a node compromise to the immediate network neighborhood of the compromised node. The design of the protocol is motivated by the observ ..."

The performance of mutual funds in the period 1945-1964
