Trust, Security and Privacy in VANETs A Multilayered Security Architecture for C2C-Communication

摘要

As we move into an era of networked systems, vehicles are also being equipped with wireless communication technologies. Based on these abilities, different vehicles are able to exchange information related to traffic safety and thus increase traffic safety and efficiency. A particular vehicle could for example be warned about danger situations that have been detected by sensors of another vehicle. In this context, we consider multi-hop messages, e.g., Vehicle based Road Condition Warning and single hop messages, e.g., Emergency Electronic Brake Lights. However, the introduction of safety message raises severe security challenges. Since these messages influence the behaviour of critical components, a misuse of safety messages can result in serious accidents.
