Automobile PIN code generation system and method

Abstract

The invention discloses an automobile PIN code generation system. The system comprises a PIN code calculation function module, the PIN code calculation function module is used for generating a corresponding PIN code according to an obtained automobile VIN value through a preset algorithm and sending the PIN code to electric detection equipment, and the PIN code is written into an anti-theft control system in an automobile by offline electric detection equipment. The system has the advantages that the calculation algorithm is integrated in the MES system of a main engine plant. Compared with a systems in the prior art that the calculation algorithm is integrated in electric detection equipment, the system of the invention is more convenient and reliable, does not depend on electric detection equipment manufacturers, can automatically modify confidentiality, and is safe and reliable.

Description

technical field [0001] The invention relates to the field of automobile safety, in particular to a system and method for generating an automobile PIN code. Background technique [0002] With the continuous advancement of automobile technology and high-tech development, automobiles have become the most important means of transportation for people. With the increasing number of car theft cases, the automobile anti-theft control system came into being; the automobile electronic anti-theft system uses non-contact radio Sensing technology carries out the transmission, calculation and authentication of passwords, and the key, electronic anti-theft device, and engine control unit form an organic anti-theft system through perfect anti-theft strategies, which greatly improves the overall security of automobile anti-theft. [0003] In the entire anti-theft system, the security code (PIN) is the core security password of the OEM. When each vehicle goes offline, the electric inspection ...

Problems solved by technology

[0003] In the entire anti-theft system, the security code (PIN) is the core security password of the OEM. When each vehicle goes offline, the electric inspection equipment will write the PIN into the anti-theft controller, engine controller and other related systems; Authentication with the anti-theft controller, successful authentication enables the car to start normally. In the existing technology, the PIN algorithm is designed by the OEM, and the OEM provides the algorithm for the software development and use of the off-line equipment supplier. The algorithm is integrated in the off-line equipment, and the algorithm information Security will cause leakage, and complete confidentiality cannot be achieved; if the logic rules of the algorithm change, the electrical inspection equipment software cannot be applied and needs to be redeveloped, and there is a problem of long development workload and high development costs
