Automotive Proxy-based Security Architecture for CE Device Integration

ncreasing adoption of Consumer Electronic (CE) devices inthe automotive world encourages car makers to propose new CE-relatedfeatures each year. However, car complexity and security concerns slowdown this process. The ubiquitous and personal nature of such devicesrepresents a real threat for car IT systems. We believe that the arrival ofIP standards in car should solve most of these issues. In this paper, wedescribe a proxy-based security architecture for an on-board IP-basednetwork allowing deep and total integration of external mobile wirelessservices. The proposed architecture has been integrated in an automotiveIP-based communication middleware and supports security mechanismscomplying with the highly demanding automotive requirements.
