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 ..."

management for multicast communication sessions. It focuses on two main areas of concern with respect to key management, which are, initializing the multicast group with a common net key and rekeying the multicast group. A rekey may be necessary upon the compromise of a user or for other reasons (e

Separating key management from file system security

by David Mazieres, Michael Kaminsky, M. Frans Kaashoek, Emmett Witchel , 1999
"... No secure network file system has ever grown to span the In-ternet. Existing systems all lack adequate key management for security at a global scale. Given the diversity of the In-ternet, any particular mechanism a file system employs to manage keys will fail to support many types of use. We propose ..."

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 ..."

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

Self-Organized Public-Key Management for Mobile Ad Hoc Networks

by Srdjan Capkun, Levente Buttyán, Jean-Pierre Hubaux - IEEE TRANSACTIONS ON MOBILE COMPUTING , 2003
"... In contrast with conventional networks, mobile ad hoc networks usually do not provide online access to trusted authorities or to centralized servers, and they exhibit frequent partitioning due to link and node failures and to node mobility. For these reasons, traditional security solutions that requ ..."

that require online trusted authorities or certificate repositories are not well-suited for securing ad hoc networks. In this paper, we propose a fully self-organized public-key management system that allows users to generate their public-private key pairs, to issue certificates, and to perform authentication

Dynamo: amazon’s highly available key-value store

by Giuseppe DeCandia, Deniz Hastorun, Madan Jampani, Gunavardhan Kakulapati, Avinash Lakshman, Alex Pilchin, Swaminathan Sivasubramanian, Peter Vosshall, Werner Vogels - IN PROC. SOSP , 2007
"... Reliability at massive scale is one of the biggest challenges we face at Amazon.com, one of the largest e-commerce operations in the world; even the slightest outage has significant financial consequences and impacts customer trust. The Amazon.com platform, which provides services for many web sites ..."

A Key Management Scheme for Wireless Sensor Networks Using Deployment Knowledge

by Wenliang Du, Jing Deng, Yunghsiang Han, Shigang Chen, Pramod K. Varshney , 2004
"... To achieve security in wireless sensor networks, it is important to be able to encrypt messages sent among sensor nodes. Keys for encryption purposes must be agreed upon by communicating nodes. Due to resource constraints, achieving such key agreement in wireless sensor networks is non-trivial. Many ..."

Operations have low complexity (O(log N) for joins or leaves), thus granting scalability even for very large groups. We also present a novel
