英文摘要 | Vehicular Ad-hoc Networks (VANETs) plays an important role in improving traffic management. Due to the openness of wireless channels, how to ensure the security and privacy of communication has become a huge challenge for the VANETs. The tamper-proof based scheme has been proposed to solve the above problems, which requires stores system master key in the tamper-proof device (TPD) of vehicles to generate pseudonyms and signatures. For the sake of communication security, the system master key must be updated regularly. Recently, in order to update the master key more efficiently, the NERA scheme is proposed for secure vehicle communications. However, the NERA scheme is vulnerable against some security threats, such as impersonation attacks, identity privacy threats. Accordingly, an improved RSU-based authentication scheme with Elliptic Curve Cryptosystem (ECC) is proposed, in which the security of the proposed scheme is enhanced greatly to resist the security threats during pseudonym and private key generation process. Compared with the previous NERA, the improved scheme proved to be more secure and efficient. |
