Abstract
At present, in addressing security challenges within 5 G-era Vehicular Ad-Hoc Networks (VANET), a new protocol has been designed in this paper, named V2X-GKA (Dynamic Group Authentication and Key Agreement Protocol based on C-V2X). V2X-GKA utilizes cryptographic techniques such as ECDLP and DBDH to effectively mitigate risks associated with certificate forgery and key theft. Through the integration of authentication and group key agreement mechanisms, the protocol facilitates dynamic member management and secure key updates without necessitating complete protocol re-execution. This approach not only ensures both forward and backward security but also optimizes algorithmic processes, rendering it highly suitable for real-time, high-speed mobile environments. Through necessary security analysis, it is confirmed that the V2X-GKA scheme in this paper meets the existing security objectives. Compared with other similar schemes, it exhibits a certain degree of completeness and superiority, particularly in open-channel scenarios.
