具有技术保护功能的单片机程序固化系统设计

MCU Program Downloading System with IP Protection

本设计是一种特殊的加解密系统,目的是保护技术开发者的知识产权。通过远程监测和控制产品单片机的程序固化过程,保证技术开发者与产品生产者根据生产量进行的合理利益分配的落实。技术开发者对生产方的技术购入(注册)、生产(产量授权)和技术升级进行远程监控,如同网上购物一样方便、安全。利用AVR单片机具有的串行编程以及Boot自编程功能实现产品单片机的程序固化操作,保证产品生产的顺利执行。

A special encryption/decryption system is designed, with the purpose of protecting developers＇ intellectual properties. Through remote-supervision and controlling the process of program download of MCU, it guarantees that the profit is distributed appropriately based on production quantity between developers and producers. Its technical character is that developers can supervise technology purchase （register）, production （production authorization） and technical upgrading of the producers, as conveniently and safely as purchasing on the Internet. Serial programming and Boot self-programming functions of AVR MCU are used to carry out the operation of program download of MCU and to ensure smooth production.
