基于SecOC的车载网络通信安全模型研究.

The increase of in-vehicle electronic equipment makes the in-vehicle network face more and more threats. The lack of authentication of the Electronic Control Unit in the in-vehicle network and the lack of encryption of the communication data of the Controller Area Network make the in-vehicle network vulnerable to replay, ECU injection, man-in-the-middle forged messages, eavesdropping, etc, Witch make serious consequences. Aiming at the current vehicle network threats, a vehicle network security communication model based on SecOC is proposed. This model uses the SM4 cryptographic algorithm and the improved key management based on Bkake2 s to realize the authentication of the vehicle ECU and the encryption and authentication of the vehicle network message. Finally, after analysis and testing, the model can protect the invehicle network security and be more efficient. [ABSTRACT FROM AUTHOR]
