  4. Safety and Privacy in Vehicular Communications (Extended abstract) • VANET Potential Applications • Traffic safety related applications, Traffic optimization, Value-added services in VANETs • Characteristics of VANETs: • Security Requirement: • Threshold authentication; Anonymity; Revocability • Existing Countermeasures for Securing VANETs: • Posteriori or Priori Countermeasures • Combination Countermeasure: • Message-Linkable Group Signatures

  5. Balanced Trustworthiness, Safety, and Privacy inV2V Communications • Threshold V2V Authentication Protocol • Distinguished features • Posteriori and Priori Countermeasures • Adaptively adjustable threshold • New crypto tech • Message-Linkable Group Signature • Speedup message verification in VANETs • Batch-Message Processing • Simulations

  6. A Scalable Robust Authentication Protocol For Secure Vehicular Communications • Contribution： • Relief from heavy complicated distribution and revocation • Avoidance of computation and communication bottlenecks • Reduction of the strong reliance on tamper-proof devices • Main idea: • Each RSU maintains an on-the-fly group within its communication range • Vehicles anonymously generate V2V messages • Vehicles verify anonymous V2V messages from other vehicles. • Crypto techniques: • Signcryption • Group signature

  7. Conciliating Liability and Privacy in Large-Scale VANETs. • Contribution: • Elimination of certificate management • Robust system setup • Emergency message generation • Fast message verification • Main ideas: • Hierarchical  organization of VANET • Subgroup partition • Identity based authentication • Selfish verification mechanism • Crypto techniques: • Identity-based group signatures (IBGS) • Threshold secret sharing techniques • Online/Offline signature)
