A digital certification management mechanism in mobile ad hoc network

Abstract

Routing services in Mobile Ad hoc Network (MANET) are the goal of denial of service (DoS) attack forms, such as: Blackhole, Sinkhole, Grayhole, Wormhole, Flooding and Whirlwind. There are some related researches to improve security performance of routing services, which typically are hashed ad hoc on-demand distance vector routing (H(AODV)), ad hoc routing protocol based on the concept of one time password (OTP_AODV), secure ad hoc on-demand distance vector (SAODV) and authenticated routing for Ad hoc Networks (ARAN). They require hypothetical conditions that public key infrastructure (PKI) is available, Ad hoc on-demand distance vector routing protocol using trust authentication mechanisms (TAMAN) supported a digital certificate verification service adaptively and quickly to the dynamic topology of network without relying on any certification authorities (CA). However, node’s digital certificate is installed manually and TAMAN has not digital certificate provision and revocation mechanisms. Hence, it is restricted to operate on MANET where nodes move randomly. In this article, we propose a digital certificate management mechanisms (DCMM) based on X.509 standard which supports storing digital certificate, provision and revocation without any PKI. We have implemented DCMM on TAMAN protocol and simulated with NS2 using static and mobility scenarios with speed 30m/s. Simulation results show that digital certificates providing process completely after 70 seconds for 100 member nodes using static scenarios and 270 seconds using mobility scenarios, and TAMAN performance using DCMM is reduced slightly in terms of packet delivery ratio, routing load and end-to-end delay time.
