Integration of communication security into advanced simulation environments for ITS

VANETs employ cryptographic measures - like signing and verifying messages - to ensure security and trust in vehicle-2-x communication (V2X) applications. Before deployment those V2X applications need to be validated and assessed in simulations and field operational tests. While usual key performance indicators cover network layers from PHY to networking as well as traffic efficiency and safety benefits assessing and validating the network security has not been widely addressed. We therefore present a comprehensive security simulator Agez that allows us to measure the impacts of the network and application security utilized in state-of-the-art vehicle-2-x communication stacks. We present how Agez can be integrated in available simulation environments and how novel security mechanisms can be easily assessed.
