“…The 5G-V2X has wider coverage, low latency, high reliability, etc., and can obtain timely and accurate access to all kinds of road status information, real-time interaction, more secure and reliable to complete the driving task [1] . As a key technology for the future of the automotive application industry, many standardization organizations allocate 5.9 GHz dedicated frequency band as the working frequency band for V2X, to meet the future vehicle network environment of diverse communication needs [2] . Due to the diversity of communication objects and rich application scenarios, there are many security risks such as identity forgery, unencrypted transmission, session hijacking, etc., easy to cause communication data leakage, interference auto-driving judgment, thus causing traffic accidents [3] .…”
