Secure LTE-Based V2X Service

Internet of Things (IoT) is the reality of a new and powerful ubiquitous technology. One of its main driving forces is the 3rd Generation Partnership Project (3GPP) Long-Term Evolution (LTE), seeking to encompass all the applications of IoT. With this trend, 3GPP has finally made the Release 14 for LTE-based vehicle to everything (V2X) service. In this proposed paper, we evaluated the new LTE-based V2X architecture in regards to V2X message delivery and security requirements. We showed that a proper resource allocation and reference point (channel) selection could accommodate all types of V2X message deliveries. However, focusing more on security, we deemed that LTE-based V2X security falls short of meeting adequate security requirements, especially, to well preserve the privacy. Hence, we proposed a privacy preserving security for LTE-based V2X service. Considering the privacy as the top security requirement, we seamlessly integrate our security scheme with the specified LTE security architecture. Our scheme is scalable while fulfilling basic wireless message security requirements. We also provide the security and performance analysis to show the robustness and effectiveness of our proposed schemes.
