A performance analysis of IPSec/AH protocol for automotive environment

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.
