Embodiment Construction

[0056] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0057] see figure 1 , which is a flow chart of the first embodiment of a vehicle program encryption method provided by the present invention.

[0058] In this example, include:

[0059] S101: Generate seed data.

[0060] S102: Generate a seed key according to the seed data.

[0061] S103: According to the seed data storage address and the seed key storage address recorded in the MAP file, store the seed data and the seed key in the target file.

[0062] When implementing this embodiment, seed data is generated first. Based on the consideration of security verification, the seed data preferably uses a string of numbers generated randomly. Of course, fixed numbers can also be used if there is a need for individualization, such as us...

Abstract

The invention provides a vehicle program encrypting and verifying method and device. The program encrypting method comprises the following steps: generating seed data; generating a seed key according to the seed data; storing the seed data and the seed key to a target file according to the seed data storage address and the seed key storage address which are recorded in an MAP file. According to the method above, corresponding seed data information can be stored in the target file, thus the target file can be effectively verified while being read, and as a result, the validity of the program file used in upgrading of a vehicle can be ensured.

Description

technical field [0001] The invention relates to the technical field of automobile automation control, in particular to a vehicle program encryption verification method and an encryption and verification device. Background technique [0002] With the rapid development of science and technology, programs are used in more and more vehicle equipment to control the vehicle, so as to improve the driving experience of users. [0003] In the prior art, the infusion and installation of the automation program will be completed when the vehicle leaves the factory. If the vehicle manufacturer upgrades the automation program, the installation program can be released and the maintenance personnel or even the user can upgrade the vehicle through the device interface. [0004] However, during the upgrade process, there is a certain risk of wrong operation by maintenance personnel or users. For example: a maintenance personnel or a user downloads a wrong upgrade program (such as another ve...
