Resilient Security Mechanism for Wireless Ad hoc Network

Abstract

A wireless multihop network is emerging as one of the most important technologies in the field of ubiquitous networking. However, a number of formidable challenges remain, several of the most crucial been associated with robustness and network security. In this paper, we introduce a comprehensive resilient security framework for wireless ad hoc networks that are using multipath routing. It deploys an integrated multisignatures scheme and uses a self-certified public keying technique to ensure secure route discovery. In addition, it uses the Schnorr signature scheme along with an information dispersal algorithm to ensure secure data transfer. We provide security analysis of the proposed approach and compare it with several existing popular schemes. It can be seen that the proposed approach is more secure than other existing schemes. We also evaluated the proposed approach by means of computer simulation and compared its performance to that of the existing popular schemes. The results are in favor of the proposed technique in terms of efficiency and effectiveness.
