Abstract

Vehicular {\em ad hoc} networks (VANETs) allow wireless
communications between vehicles without the aid of a central
server. Reliable exchanges of information about road and
traffic conditions allow a safer and more comfortable travelling
environment. However, such profusion of information may allow
unscrupulous parties to violate user privacy. On the other hand,
a degree of auditability is desired for law enforcement and maintenance
purposes. In this paper we propose a
Threshold Anonymous Announcement service using direct anonymous
attestation and one-time anonymous authentication to simultaneously
achieve the seemingly contradictory goals of reliability, privacy
and auditability.
