一种驱动类软件的保护方法

A Protection Method for Driver Softwares

首先讨论了软件加密技术的现状及常用的几种加密技术,并分析了驱动类软件加密的必要性及其限制。然后详细描述了一种驱动类软件的保护方法及其实现,针对每种限制均给出了完整的解决方案和具体的实现,并描述了此种保护方法中采用的几种反破解技术。最后,讨论了这种方法的局限性及其改进。

This article first describes the current status of software encryption and some technologies on it,then analyzes the necessarily of encryption in driver modules and a few restrictions to overcome.Further,we introduces a method to provide the protection of driver modules and the entire implementation.Each of the restrictions analyzed is resolved by the implementation.Some anti-cracking technologies in the implementation are also described afterward.At the end,we show some shortage of the current version and our expectation.
