Embodiment Construction
[0058] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0059] Various embodiments for implementing the present invention will now be described with reference to the accompanying drawings. In the following description, use of suffixes such as 'module', 'part' or 'unit' for denoting elements is only for facilitating description of the present invention and has no specific meaning by itself.
[0060] like figure 1 and figure 2 As shown, the first embodiment of the present invention proposes a safety verification system, which includes a diagnostic device 100 and an electronic control unit 200;
[0061]The diagnostic device 100 is configured to send an instruction to request a seed to the electronic control unit 200; to generate an unlock key according to the seed data, and the seed data is generated after the electronic control unit 200 obtains the instruction to request ...

The invention discloses a safety verification system and method. The method comprises the steps that 1, diagnosis equipment sends a seed request instruction to an electronic control unit; 2, the electronic control unit acquires the seed request instruction and generates seed data; 3, the diagnosis equipment generates an unlocking key according to the seed data; 4, a safety algorithm library file of the electronic control unit generates a safety key according to the seed data; 5, whether the unlocking key is the same as the safety key or not is judged; 6, judgement result information is sent to the diagnosis equipment. According to the system and method, a safety algorithm file and a DEMO software file are compiled to generate the safety algorithm library file, and the safety algorithm library file is called for unlocking when ECU unlocking is conducted. Accordingly, leakage of safety algorithm source codes is effectively prevented, and the management cost is greatly reduced.
Description
technical field [0001] The invention relates to the field, in particular to a safety verification system and method. Background technique [0002] Automobile ECU, as the core component of a certain functional unit of the automobile, the security of the internal data of the ECU directly affects the safety of the automobile, especially some important data inside the automobile ECU, after it is matched with the automobile, it must be The current common practice for high security level protection is to use security certification (based on a certain security algorithm) for protection; that is to say, the above high security data can only be modified after passing the internal security certification of the ECU. [0003] The safety algorithm of the automotive ECU is the most important information of the whole vehicle. Important information such as ECU refresh, ECU configuration, and ECU parameter selection are all protected by the safety algorithm. At present, domestic OEMs mainly...
