Efficient Noninteractive Secure Protocol Enforcing Privacy in Vehicle-to-Roadside Communication NetworksInternational Journal of Vehicular Technology (2012)
Vehicular ad hoc networks (VANETs) have attracted extensive attentions in recent years for their promises in improving safety and
enabling other value-added services. In this paper, we propose an efficient noninteractive secure protocol preserving the privacy of
drivers in vehicle-to-roadside (V2R) communication networks with the ability of tracing malicious drivers only by a third trusted
party (TTP), who is assumed to be fully trusted. Our proposed protocol can provide these complex requirements depending on
symmetric cryptographic algorithms. The drivers can change the symmetric key used for message encryption with each message
transmission and find noninteractively new values to be correctly used for verification and tracing in case of malicious behavior.
The advantages of symmetric cryptographic algorithms over asymmetric algorithms are the faster processing speed and the shorter
message length whichmakes it suitable for real-time applications such as V2R communications. An efficient key revocation scheme
will be also described.
