Embedded program burning method and system of chip

Abstract

The embodiment of the invention discloses an embedded program burning method and system for a chip, and the method comprises the following steps: a burning step: burning an auxiliary loading / protecting program in the chip in a white chip state, and then burning an application program which comprises a general program and a core program; and an execution step: executing the application program, decrypting the core program, reconstructing the core program into a complete unencrypted application program, and executing the unencrypted application program. According to the method, an auxiliary loading / protecting program is burnt firstly, and after burning is completed, the chip is in a protected state and cannot be connected through a universal tool any more; the process data involved in the method are exclusively encrypted, and the process data are different in each time, so that the process data cannot be simply intercepted for simulation and reprocessing; and program forms in embedded products produced by the method are different, and even through technical cracking, the embedded products can only be matched with current hardware for use, and have no replicability, namely, have no cracking value.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a chip embedded program burning method and system. Background technique [0002] Embedded systems mainly include embedded chips and the minimum hardware systems necessary for their work, peripheral function hardware and embedded software that meet the application requirements. With the development and popularization of science and technology, embedded system equipment is ubiquitous, and it is commonly seen in daily life. The motor controller, one of the "big three electrics" in electric vehicles, is a typical embedded system device. [0003] The motor controller research and development company is a strong technology-based enterprise. The confidentiality of core data is often crucial, and the confidentiality of embedded software is even more important. Once leaked, the light will cause economic losses, and the most serious will affect the development of the company ...

AI Technical Summary

Problems solved by technology

[0006] For finished products that have been produced and sold, in order to prevent crackers from reading the embedded software directly through the JTAG port and other means that come with the chip, the password lock that comes with the chip is generally opened, but the encryption rules that come with the chip are common and have a wide range of applications. Professionals / companies succeed in cracking, and only need to pay a little remuneration to obtain files that can be mass-produced
