Abstract The Vehicular Ad-hoc Network (VANET) is the fundamental of smart
transportation system in the future, but the security of the communication between
vehicles and vehicles, between vehicles and roadside infrastructures have become
increasingly prominent. Certificateless aggregate signature protocol is used to address
this security issue, but the existing schemes still have many drawbacks in terms of
security and efficiency: First, many schemes are not secure, and signatures can be forged
by the attacker; Second, even if some scheme are secure, many schemes use a large
number of bilinear pairing operation, and the computation overhead is large. At the same
time,… More >
