Abstract:
|
Vehicular Ad Hoc Networks (VANETs) require some
mechanism to authenticate messages, identify valid vehicles, and
remove misbehaving ones. A Public Key Infrastructure (PKI)
can provide this functionality using digital certificates. In PKI,
key management and corresponding issuance and revocation
of digital certificates is one of the key issues that have to be
solved. The IEEE 1609.2 standard states that VANETs will
rely on the use of certificate revocation lists (CRLs) to achieve
revocation. In this paper, we analyze the problems of using CRLs
in these type of networks. Moreover, we describe the Risk Aware
Revocation (RAR) mechanism that improves the traditional use of
CRLs. RAR takes advantage of the two distinct channel types in
VANETs to increase the freshness of the revocation information.
Moreover, RAR allows users to gauge the risk of operating in a
VANET when using CRLs. |
