Embodiment Construction

[0043] First of all, it should be pointed out that the term "computer" used in this article not only includes well-known general-purpose computer equipment such as desktop computers, notebook computers, and tablet computers, but also includes industrial computers such as industrial computers and special-purpose computers. Equipment, also includes any computing device suitable for use but which may exist in other forms. In addition, the term "peripheral interface" refers to an existing known form of interface provided on the above-mentioned "computer" for connecting external devices. This type of interface includes ordinary USB interface, small USB interface, RS232 interface, etc., and also refers to Other types of interfaces that may take other forms in the future and still function to connect external devices to the "computer" through which they are described.

[0044] The following will pass in the figure 1 and figure 2 The process of the two embodiments shown in the figu...

Abstract

The invention relates to an automobile electronic control unit (ECU) secret key simulation implementation method, a system and a verification method thereof. The automobile ECU secret key simulation implementation method includes that an automobile ECU simulation operating model is constructed and operated in a computer, an encryption unit is connected with the computer in a communication mode, the encryption unit has the same encryption processing business rules with an encryption control which is used for generating a secret key in the automobile ECU, an automobile diagnostic apparatus is connected with the computer and a vehicle-mounted bus in a communication mode, required safety algorithm numbers are set by the automobile diagnostic apparatus, a signal request seed numbers are transmitted to the simulation operating model by the automobile diagnostic apparatus, the safety algorithm numbers and the seed numbers back fed and output from the simulation operating model are transmitted to the encryption unit so that the encryption unit can generate the secret key relevant to the safety algorithm numbers and the seed numbers, and a communication with the encryption unit is performed for an analysis to obtain the secret key. The automobile ECU secret key simulation implementation method, the system and the verification method thereof have the advantages that the development design efficiency is high, the usage is reliable, the application is convenient and fast, the cost is saved, debugging workload and difficulties are remarkably reduced, and the like.

Description

【Technical field】 [0001] The invention relates to the technical field of key processing, in particular to an automobile ECU (Electronic Control Unit, electronic control unit) key emulation implementation method, an automobile ECU key emulation implementation system, and an automobile ECU key emulation verification method. 【Background technique】 [0002] With the development of the times and the progress of science and technology, the automobile industry has achieved rapid development, and many details of modern automobiles all reflect a high level of technology. For example, a large number of ECUs will be used in the current production of automobiles to perform real-time and accurate monitoring of the engine, automatic transmission, drive system, anti-lock braking system, active suspension system, airbag system, etc. This situation is especially common in many middle and high-end cars. At this time, there will be as many as a dozen or even more than 20 ECUs used in these car...
