Distributed detection of node replication attacks in sensor networks

by Bryan Parno, Adrian Perrig, Virgil Gligor - PROCEEDINGS OF THE IEEE SYMPOSIUM ON SECURITY AND PRIVACY , 2005
"... The low-cost, off-the-shelf hardware components in unshielded sensor-network nodes leave them vulnerable to compromise. With little effort, an adversary may capture nodes, analyze and replicate them, and surreptitiously insert these replicas at strategic locations within the network. Such attacks ma ..."

The Sybil attack in sensor networks: Analysis & Defenses

by James Newsome, Elaine Shi, Dawn Song, Adrian Perrig - THIRD INTERNATIONAL SYMPOSIUM ON INFORMATION PROCESSING IN SENSOR NETWORKS, IPSN, 26 – 27 APRIL 2004 PAGE(S): 259 – 268 , 2004
"... Security is important for many sensor network applications. A particularly harmful attack against sensor and ad hoc networks is known as the Sybil attack [6], where a node illegitimately claims multiple identities. This paper system-atically analyzes the threat posed by the Sybil attack to wireless ..."

Memory Efficient Protocols for Detecting Node Replication Attacks in Wireless Sensor Networks

by Ming Zhang, Vishal Khanapure, Shigang Chen, Xuelian Xiao
"... Abstract—Sensor networks deployed in hostile areas are subject to node replication attacks, in which an adversary compromises a few sensors, extracts the security keys, and clones them in a large number of replicas, which are introduced into the network to perform insider attacks. Memory overhead, e ..."

Efficient distributed detection of node replication attacks in sensor networks

by Bo Zhu, Venkata Gopala, Krishna Addada, Sanjeev Setia, Sushil Jajodia, Sankardas Roy - in Proc
"... Wireless sensor nodes lack hardware support for tamper-resistance and are often deployed in unattended environ-ments, thus leaving them vulnerable to capture and com-promise by an adversary. In a node replication attack, an adversary uses the credentials of a compromised node to surreptitiously intr ..."

introduce replicas of that node into the net-work. These replicas are then used to launch a variety of attacks that subvert the goal of the sensor application, and the operation of the underlying protocols. We present a novel distributed approach called Localized Multicast for detecting node replication

An Approach in Detection of Replication Node in Wireless Sensor Networks: A Survey

by Raju M, Selvan M
"... Abstract — This paper presents a complete study on the detection of replication node in wireless sensor networks. Consider a very severe and important physical attack on WSN which is called node replication attack or clone attack. It is also known as identity attack. Several algorithms are developed ..."

A Survey of Dynamic Detection of Node Replication Attack in Wireless Sensor Network Dr.M.BalaGanesh

by unknown authors
"... Abstract- A survey of MANET plays an major role in data communications. The node can be formed automatically without any centralised infrastructure, even though the nodes are formed automatically the replication of data to the node’s are unavoidable. In single point attack that brings the whole netw ..."

A Randomized, Efficient, and Distributed Protocol for the Detection of Node Replication Attacks in Wireless Sensor Networks

by Mauro Conti, Roberto Di Pietri, Luigi V. Mancini, Alessandro Mei - MOBIHOC'07 , 2007
"... Wireless sensor networks are often deployed in hostile environments, where an adversary can physically capture some of the nodes. Once a node is captured, the attacker can re-program it and replicate the node in a large number of clones, thus easily taking over the network. The detection of node rep ..."

An Asynchronous Node Replication Attack in Wireless Sensor Networks

by Tanmoy Jianying Zhou , Kanti Das , Javier Lopez
"... Abstract Applications of wireless sensor network (WSN) are growing significantly, and many security protocols meant for WSN have been proposed. One of the unique problems of WSN is that the sensor nodes are not tamper resistant as the main attraction of deploying WSN is its low cost. Node replicati ..."

However, we show in this paper that their distributed detection protocol is vulnerable to an asynchronous node replication attack. Further, we

Clone Attack Detection Protocols in Wireless Sensor Networks: A Survey

by J. Anthoniraj
"... Wireless Sensor Network (WSN) is a collection of autonomous sensor nodes which are low cost hardware components consists of sensor nodes with constraints on battery life, memory size and computation capabilities to monitor physical (or) environmental conditions. WSN is deployed in unattended and uns ..."

. Then these clones can be deployed in all network areas, they can be considered as legitimate members of the network, so it is difficult to detect a replicated node. WSN can be either static (or) mobile, in that centralized and distributed clone attack detection methods are available. In this paper we analysis
