Security and Privacy in Vehicle Safety Communication Applications 2006-01-1425
Securing vehicle-to-vehicle and vehicle-to-roadside communication is an indispensable prerequisite for its deployment and real world use. Due to the large number of independent network members and the presence of the human factor, it is highly probable that misbehavior will arise in the future Vehicular Networks. We propose a Secure and Privacy-Preserving Communication framework. The framework relies on a tamper-resistant device and a cryptographic technique called group signatures. We view the vehicular network as a large scale distributed system. All access to the system should be authorized. The controlled access is enforced by a trusted tamper-resistant device in the vehicle. The accountable privacy is achieved by using the group signature technique.
