Abstract

The configuration of security mechanisms in automotive on-board networks makes it necessary to define and deploy adapted security policies. This paper discusses how to design policy engines that implement an effective enforcement in such architectures despite the complexity of the protocol stacks of on-board electronic control units. It also evaluates how policies expressed in XACML can be adapted to the automotive environment efficiency requirements despite the limited computational power of those units and network bandwidth limitations.
