Abstract: |
|
|
In Vehicular Ad hoc NETworks (VANETs), vehicles have to be protected from the misuse of their private data and the attacks on their privacy. Here the authentication issues with privacy preservation and non-repudiation in VANETs have been considered. The self-generated public-key cryptography PKC based pseudonyms are also used as identifiers instead of vehicle IDs for the privacy-preserving authentication, while the update of the pseudonyms depends on vehicular demands. The existing ID-based signature (IBS) scheme and the ID-based online/offline signature (IBOOS) scheme are used, for the authentication between the road side units (RSUs) and vehicles, and the authentication among vehicles, respectively. Authentication, privacy preservation, non-repudiation have been analyzed for VANETs. Typical performance evaluation has been conducted using efficient IBS and IBOOS schemes. |
