Eun-Kyung Ryu and Kee-Young Yoo Certificateless broadcast authentication for vehicular ad hoc networks Security and Communication Networks 6
We propose a new certificateless broadcast authentication scheme for securing beacon messages in vehicular networks, which uses the mechanism of Schnorr signature as an underlying primitive. The main goal of our scheme is not to impose the requirement of the public key infrastructure that makes existing schemes impractical. We also show how the scheme can be extended to provide a practical solution for the problem of key distribution in general-purpose vehicular applications.
