ABSTRACT

Vehicular Ad Hoc Networks are usually operated among vehicles moving at high speeds, and thus their communication relations can be changed frequently. The presented solution is based on attribute-based encryption (ABE) to construct an Attribute-Based Vehicular Network Security Policy Enforcement framework. In vehicular ad hoc networks, which include both vehicles and roadside units, security and privacy research is mainly based on the entity level or data level. To enable the security data access control policy in vehicular ad hoc networks, we use attributes as the basic properties of vehicles for access control and secure group communications in vehicular ad hoc networks. Attribute-Based Vehicular Network Security Policy Enforcement is flexible in that it can dynamically change encryption keys depending on the Attribute-Based Vehicular Network Security Policy Enforcement situations.
