Abstract


Vehicular AdHoc Networks (VANETs) scheme help to authenticate messages, identify the valid vehicles and Preserves the privacy of each vehicles.The Objective of PublicKeyInfrastructure (PKI) is to enable secure, convenient and acquisition of public keys and provide functionality using certificates. However, fixed public keys allow an eavesdropper to associate a key with a vehicle and a location, violating drivers privacy .In this work we propose a VANET time stamped key management scheme based on Temporary Anonymous Certified Keys (TACKs) which replaces the time consuming CRL checking process. To reduce the message overhead substantially and to enhance the effectiveness of the message verification, BSpecs algorithm is used. Our scheme efficiently prevents malevolent vehicles from linking with dif erent keys and provides timely revocation of misbehaving participants while maintaining the same or less overhead for vehicle-to-vehicle communication.
