An improved authentication scheme for applying RFID in VANETs

This paper presents an improved authentication scheme for Radio-frequency identification (RFID) applied in VANETs. As often being considered as a precondition for the realization of IoT, RFID can be utilized in the vehicles, so as to make the vehicles identifiable and inventoriable by computers as long as they are fitted out with radio tags. One of the main concerns is to address the large number of security and privacy issues. A few light symmetric key management schemes have been proposed for RFID scenarios. We suggest EKA2 which is a new certificate revocation status validation scheme, and we use the concept of clustering from data mining to evaluate the trustiness of digital certificates.
