Secured Routing Deterrent to Internal Attacks for Mobile AD HOC Networks
Menaka Sivakumar · Journal of Engineering Science and Technology Review · 2018
Security is a vital requirement for communication between mobile nodes in a hostile environment.Mobile nodes are prone to various attacks in a hostile environment.Routing is one of the crucial tasks where a malicious node can gain access to the network.This paper presents a mitigation mechanism to confront internal attacks launched by the misbehaving nodes.The nodes which launch security threats in the network after participating in the route discovery and data transmission are referred as misbehaving nodes.Such authenticated nodes misbehave either due to malicious software or get compromised.The compromised or misbehaving nodes attack on the confidentiality and authentication security services.The nodes generally gain access and become part of the network during the routing process.This works proposes a secured routing deterrent to internal attacks (SRDIA) that mitigates the internal threats launched by the compromised nodes.The proposed scheme in this paper is a defense mechanism against routing security threats for mobile ad hoc networks using ID based cryptography.In addition hash chain based security association is used for authentication and key management.This technique aims at defending from the security threats caused by compromised nodes like Byzantine attack, invisible node attack, Sleep Deprivation, location disclosure etc.In this research work an efficient authentication technique using hash chain and session key establishment is proposed.A lightweight hash algorithm "BLAKE" is used for the implementation of authentication for resource constraint devices and "PRESENT", a symmetric key encryption algorithm to secure the data exchange among nodes.The outcome of the simulation results demonstrates percentage increase of packet delivery ratio and throughput in presence of malicious nodes.
