Embodiment Construction

[0100] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention.

[0101] The degree of encryption of the Android operating system is an important factor that determines whether it can be decompiled. Compared with the Java source code, the C / C++ source code of the Native layer has higher security and is not easy to be decompiled. Based on this, the present invention provides a method for protecting car-machine data based on the Android operating system, which can generate a unique key corresponding to each car-machine in the Native layer of the Android operating system, and use the unique The key encrypts the data on the car terminal, which greatly improves the encryption degree of the car terminal.

Abstract

The invention relates to the technical field of computers, in particular to a vehicle-mounted machine terminal data processing method and device and a vehicle, and aims at solving the technical problem of how to improve the data safety of Android operation system-based vehicle-mounted machine terminals. For the aim, the vehicle-mounted machine terminal data processing method comprises the following steps of: obtaining preset vehicle-mounted machine feature information of a vehicle-mounted machine terminal in a Native layer of an Android operation system and generating a unique secret key according to the preset vehicle-mounted machine feature information; and encrypting / decrypting vehicle-mounted machine terminal data by utilizing the generated unique secret key. Based on the steps, the secret key cannot be obtained through the Native layer to decrypt the vehicle-mounted machine terminal data even the Android operation system is transplanted, so that the vehicle-mounted machine terminal data is effectively protected. Meanwhile, the device and the vehicle can be used for executing and realizing the method.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a data protection method, device and vehicle at the vehicle end. Background technique [0002] In-vehicle infotainment system (In-Vehicle Infotainment, IVI) is a vehicle-mounted integrated information processing system formed by using a vehicle-specific central processor based on the body bus system and Internet services. It can realize audio-visual playback, navigation, weather, Mileage indication and other functions. However, since the Android operating system is a free and open-source operating system based on Linux, it is very easy to be reverse-compiled, resulting in the leakage of important data in the vehicle infotainment system. Contents of the invention [0003] In order to solve the above-mentioned problems in the prior art, that is, to solve the technical problem of how to improve the data security of the car terminal based on the Android operating system....
