Embodiment Construction

[0036] In order to express the present invention more clearly, the present invention will be further described below in conjunction with the accompanying drawings.

[0037] The Chinese name of MCU (Micro Control Unit) is a micro control unit, also known as a single chip microcomputer (Single Chip Microcomputer) or a single chip microcomputer. Timing counters and various I / O interfaces are integrated on a chip to form a chip-level computer, which can be used for different combination controls for different applications.

[0038] Writer is also called burner, programmer. In Taiwan, the burner is also called a burner; after arriving in the mainland, the reason why customers call it a "programmer" is because the English name is PROGRAMMER, which is the same as the general software programmer, so it is called "Compiler". The programmer is actually a tool for writing data on programmable integrated circuits. The programmer is mainly used for programming (or flashing) chips such as...

Abstract

The invention discloses remote encryption, decryption and writing processing methods for an MCU writer. The encryption method comprises the following steps: (a) generating an encryption key corresponding to a name password of the MCU writer by a host end special control software according to the name password of the writer; (b) firstly encrypting an original data code by the encryption key; (c) further encrypting the encrypted data or the code by the host end special control software, and converting into a binary file which can be provided for a client and can be processed by the client; (d) placing the encrypted binary file on an Internet host for remote downloading. By adoption of the host end special control software, a client end special control software and Internet transmission, remote encryption control of the MCU writer is realized; back-and-forth object express delivery of the MCU writer is avoided, and the authorization operating efficiency of the data code is greatly improved.

Description

[0001] technical field [0002] The invention relates to the field of electronic technology, in particular to a remote encryption, decryption and programming processing method for an MCU programmer. [0003] Background technique [0004] At present, when a general solution provider authorizes software programming for customers, it will set a quantity encryption in the programmer, and then send the MCU programmer to the customer for batch programming on the production line. When the programming quantity of the production line reaches the authorized quantity, if the customer needs to continue programming or has other new products that need to be programmed, the customer needs to send the programmer back to the solution provider for re-authorization or another authorization. In this way, the operating efficiency will be reduced, and especially for foreign customers, the operating efficiency will be even lower. [0005] Contents of the invention [0006] Aiming at the defic...
