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, but needs an efficient mechanism to revoked misbehaving/compromised vehicles. The IEEE 1609.2 standard states that VANETs will rely on the use of certificate revocation lists (CRLs) to achieve revocation. However, despite their simplicity, CRLs present two major disadvantages that are highlighted in a vehicular network: CRL size and CRL request implosion. In this paper, we point out the problems when using CRLs in this type of networks. To palliate these issues, we propose the use of Authenticated Data Structures (ADS) that allow distributing efficiently revocation data. By using ADS, network entities can check the status of a certificate decreasing the peak bandwidth load in the distribution points. |
