An ID-Based Privacy Preservation for VANET

VANET (Vehicular Ad-Hoc Network) is a special kind of message network. Authentication is an important security service for both vehicles to vehicle communications (V2V) and vehicle to roadside communications (V2R). The most Challenges and issues in the Vehicular Ad hoc network (VANET) are security and integrity. Vehicles will be threatened from misuse of their remote data and attack their private information, and capable of being reviewed form accidents or problems. In the proposed scheme, asymmetric key concept and PKC (Public Key Cryptography) were used. In ID Based Privacy Preservation for VANET, we use the Public Key Cryptography (PKC) to the pseudonym generation, which ensure authentic third party to achieve non repudiation of vehicles by obtaining vehicles Identity (IDs). PKC-based Pseudonyms are self generated also using as an identifier instead of vehicle Ids for the privacy preservation validation, while the update of the pseudonyms depends on vehicular demands. In this paper two schemes are used for authentication, Id-Based Signature (IBS) and Id-Based Online/Offline Signature (IBOOS), for the authentication between Road Side Unit (RSU) and vehicle. In the proposed system, we are increasing the safety and security in VANET environment.
