Abstract

We propose a secure and resilient WSN roadside architecture for intelligent transport systems which supports the two complementary services accident prevention and post-accident investigation. Our WSN security architecture is stimulated by the understanding that WSN roadside islands will only be rolled-out and used when hardware costs are close to the minimum. We provide a purely software based security solution which does not rely on costly HW components like road side units (RSU) or tamper resistant modules on sensor nodes. We use existing components, but also describe protocols that may be of independent interest.
