Abstract

The invention belongs to the technical field of VFP decryption, particularly relates to an automobile ECU gateway fingerprint VFP decryption system and method, and provides the following scheme for solving the problems that although an existing VFP decryption system can make corresponding response and select to start or give an alarm according to the authentication condition of an ECU, the decryption time of the decryption system is too slow, and the response time is too long. The system comprises a full server unit, an ECU gateway, an intelligent security gateway, an AESk1 decryption unit, a security storage unit, a Kpub2 encryption unit, a Kpri2 decryption unit, a database query unit and an information comparison unit, the security server unit is used for acquiring AES K1 through a secret key exchange algorithm, and the ECU gateway is used for issuing the AES K1 to each ECU. According to the invention, the chipID of each ECU is extracted through the AESk1 decryption unit, and meanwhile, the chipID is sent to the security storage unit for storage, so that the response time of the automobile can be shortened through the decryption mode, and the automobile can make a quick response.

Description

technical field [0001] The invention relates to the technical field of VFP decryption, in particular to an automobile ECU gateway fingerprint VFP decryption system and method. Background technique [0002] ECU (Electronic Control Unit) electronic control unit is a microcomputer controller dedicated to automobiles in terms of use. Like an ordinary computer, it consists of a microprocessor (CPU), memory (ROM, RAM), input / output interface (I / O), analog-to-digital converter (A / D), and large-scale integrated circuits such as shaping and driving. composition. ECU has various purposes, such as controlling the engine, controlling the gearbox, controlling the chassis, routing messages, etc., which correspond to different types of ECU controllers. The high, medium and low configuration versions of the same model will have corresponding configurations. [0003] Some car owners will directly replace the corresponding ECU in the second-hand market when a certain ECU fails. The car fac...
