A performance analysis of IPSec/AH protocol for automotive environment

Abstract

With increasing the connectivity of today's vehicles it is necessary to consider the security of such communication. This paper deals with the security requirements for in-vehicle network traffic and presents a performance analysis of IPSec/AH protocol in automotive environment. The tests were conducted on an exemplar topology using a self-developed gateway between Controller Area Network and Ethernet network based on ARM Cortex-A7 dual core processor. The main contribution of this work is evaluating the time characteristics of CAN communication "tunnelled" through Ethernet network and secured using IPSec.
