Neighborhood trustworthiness‐based vehicle‐to‐vehicle authentication scheme for vehicular ad hoc networks

Abstract

Summary Vehicular ad hoc networks (VANETs) are a type of network, which have caused widespread concern. Researchers have done many research on security and reliability of information transmission in VANETs. However, the secure transmission of emergent information, such as accident information, remains an open issue. The vehicle‐to‐vehicle authentication scheme for traffic accident information transmission not only needs to ensure the orderly and secure transmission of information but also to ensure efficient and rapid transmission. In this paper, we propose a novel scheme for VANETs named neighborhood trustworthiness‐based vehicle‐to‐vehicle authentication scheme (NTVAS). NTVAS makes reasonable utilization of cloud computing technology to evaluate the trustworthiness of vehicles for message delivery. One way vehicle‐to‐vehicle authentication ensures the efficiency of the scheme. Additionally, the concept of accident location neighborhood trustworthiness has also been innovatively presented for further transmission of accident information. The security and performance analysis indicates that our scheme is secure and efficient with low computational cost.
