Description

Technical Field

Background Technology

[0002] Over-the-air (OTA) technology is widely used in the product upgrades of intelligent connected vehicles, allowing users to improve product performance without having to visit a 4S store. However, since the product upgrade software package is transmitted through a wireless network, the integrity and authenticity of the data packet need to be guaranteed. Car manufacturers usually encrypt the upgrade data packet to ensure that the cloud data packet is securely transmitted to the vehicle. Verifying this series of protection mechanisms is a technical challenge that needs to be overcome.

[0003] Existing testing methods involve creating a virtual backend in the cloud to create a digital twin that is identical to the real user's download platform. By processing the software packages uploaded to the digital platform, the source of the software packages downloaded by the user is made to be plaintext packages, packages encrypted with incorrect algorithms, and packages encrypted with incorrect keys. This method requires the creation of a virtual backend, which has high cost and technical requirements. Furthermore, the actual channel of the twin backend is not the channel actually used by the user, and the download URL is not the real URL, resulting in low scenario fidelity.
