Abstract

The invention discloses a program encryption downloader and a working method thereof. The program encryption downloader comprises a power supply module, a key and display module, a CPU (Central Processing Unit), an SD (Secure Digital) card interface and a communication and control interface, wherein the power supply module, the key and display module, the SD card interface and the communication and control interface are connected with the CPU respectively; the power supply module is used for supplying power to each element inside the program encryption downloader. The program encryption downloader has the beneficial effects that encryption of program files becomes more flexible, limitation on downloading times is realized, the protection degree is increased, and program encryption becomes more convenient. By adopting the program encryption downloader, program downloading can be separated from a PC (Personal Computer), a corresponding simulator or a downloading tool, the decryption of the program files and data transmission with target boards are finished by using an intermediate equipment program downloader, operation becomes convenient, and one-key downloading of the program files is realized.

Description

technical field [0001] The invention relates to an embedded hardware device, in particular to a program encryption downloader and its working method, so as to implement encryption, writing times limitation and authority limitation on the program downloading of the embedded hardware. Background technique [0002] The application program of the embedded hardware will eventually be compiled into a binary program download file, and the program download file is downloaded to the embedded hardware, and executed by the hardware to realize specific functions. Leakage of program source files or program download files will lead to imitation by competitors. The program download file needs to be delivered to the production department or an external OEM unit, and it is troublesome to protect the program download file. [0003] Traditional program downloading (program downloading using a PC through a general program downloading tool) requires equipment such as a PC and a downloading tool...
