Automotive Proxy-Based Security Architecture for CE Device Integration

Increasing adoption of Consumer Electronic (CE) devices in the automotive world encourages car makers to propose new CE-related features each year. However, car complexity and security concerns slow down this process. The ubiquitous and personal nature of such devices represents a real threat for car IT systems. We believe that the arrival of IP standards in car should solve most of these issues. In this paper, we describe a proxy-based security architecture for an on-board IP-based network allowing deep and total integration of external mobile wireless services. The proposed architecture has been integrated in an automotive IP-based communication middleware and supports security mechanisms complying with the highly demanding automotive requirements.
