Replication Attack Mitigations for Static and Mobile WSN

Security is important for many sensor network applications. Wireless Sensor Networks (WSN) are often deployed in hostile environments as static or mobile, where an adversary can physically capture some of the nodes. once a node is captured, adversary collects all the credentials like keys and identity etc. the attacker can re-program it and replicate the node in order to eavesdrop the transmitted messages or compromise the functionality of the network. Identity theft leads to two types attack: clone and sybil. In particularly a harmful attack against sensor networks where one or more node(s) illegitimately claims an identity as replicas is known as the node replication attack. The replication attack can be exceedingly injurious to many important functions of the sensor network such as routing, resource allocation, misbehavior detection, etc. This paper analyzes the threat posed by the replication attack and several novel techniques to detect and defend against the replication attack, and analyzes their effectiveness in both static and mobile WSN.Comment: 12 page

Node clone detection using a stable overlay network

Wireless sensor networks consist of number of sensor nodes widely distributed in particular region to communicate and sharing the environmental information and also these data’s are stored in central location for further data prediction. Such nodes are susceptible to cloning attack where the adversary captures a node, replicates with the same identity as that of the captured node and deploys the clone back into the network, causing severe harm to the network. Hence to thwart such attacks, a distributed detection protocol is used with initiator-observer-inspector roles assigned randomly for the nodes to witness the clone and thereby broadcast the evidence through a balanced overlay network. Use of such balanced network provides high security level and reduces the communication cost when compared to other overlay networks with a reasonably less storage consumption

Optimal Layout of Multicast Groups Using Network Embedded Multicast Security in Ad Hoc Sensor Networks

This paper considers the security of sensor network applications. Our approach creates multicast regions that use symmetric key cryptography for communications. Each multicast region contains a single keyserver that is used to perform key management and maintain the integrity of a multicast region. Communications between two multicast regions is performed by nodes that belong to both regions. To ease the network management burden, it is desirable for the networks to self-organize into regions and dynamically select their keyservers. This paper shows how to determine the number of keyservers (k) to use and the size in the number of hops (h) of their multicast regions. We find that power consumption issues provide a natural trade-off that determines optimal values for these parameters. Analysis of one application shows an increase in system security with 70-80% less power overhead than existing security approaches

Clone Detection for Efficient System in WSN using AODV

Wireless sensor is wide deployed for a spread of application, starting from surroundings observance to telemedicine and objects chase, etc. For value effective sensing element placement, sensors are usually not tamperproof device and are deployed in places while not observance and protection, that creates them at risk of fully different attacks. As an example, a malicious user may compromise some sensors and acquire their private information. Then, it?ll duplicate the detectors and deploy clones in an exceedingly wireless sensor network (WSN) to launch a spread of attack that?s mentioned as clone attack. Because the duplicated sensors have an equivalent information, e.g., code and crypto graphical information, captured from legitimate sensors that may merely participate in network operation and launch attacks. Because of the low value for sensing components duplication and preparation, clone attacks became one in all the foremost essential security issues in WSNs. Thus, it?s essential to effectively detect clone attacks therefore to ensure healthy operation of WSNs

Implementation of Fuzzy Based Simulation for Clone Detection in Wireless Sensor Networks

Wireless sensor networks are usually left unattended and serve hostile environment, therefore can easily be compromised. With compromised nodes an attacker can conduct several inside and outside attacks. Node replication attack is one of them which can cause severe damage to wireless sensor network if left undetected. This paper presents fuzzy based simulation framework for detection and revocation of compromised nodes in wireless sensor network. Our proposed scheme uses PDR statistics and neighbor reports to determine the probability of a cluster being compromised. Nodes in compromised cluster are then revoked and software attestation is performed.Simulation is carried out on MATLAB 2010a and performance of proposed scheme is compared with conventional algorithms on the basis of communication and storage overhead. Simulation results show that proposed scheme require less communication and storage overhead than conventional algorithms

Kriptografi Dan Skema Keamanan Untuk Jaringan Sensor Nirkawat

This paper attempts to explore the security issues in sensor network that include constraints in sensor networks security, the requirements of secure sensor networks, attack classification and its counter measures and security mechanisms at wirelesssensor network (WSN) such as cryptography and key management. Popularity of wireless sensor network is increasing because of its potential to provide low-cost solution for a variety of real-world problem. As a special form of ad-hoc networks, sensor networks has many limitations that lead to vulnerabilities in security issues. Currently, there are many researches in the field of sensor network security. Our analysis shows that symmetric key cryptography systems are more favorable to provide WSN security services because of its computation and energy cost. Moreover, distributed combine with pre-distributed key management is important to overcome security threats and centralize threats detection is more favorable to reduce energy and computation cost of sensor nodes
