基于主动式加壳的反破解技术

Anticrack technology based on active shell

对当前主流加壳方式特征进行了分析,指出了现有的软件加壳方式在反破解上存在的缺陷.根据主动式防御的思路,设计了一个能自动追踪破解行为的防御结构.主动式加壳可防止系统内存被直接转储,保护软件的原始入口点.通过对数据指令进行动态螺旋变换,可以增强主动式加壳的安全性和反破解能力.软件加壳试验表明,这种方法在安全和性能上达到了良好的平衡.

After analyzing the characteristics of present essential shell, it is pointed out that current available software shells have shortcomings and problems in the anticrack. Supported by this foundation, a defensive structure of automatic tracking crack behavior is designed based on active defence. In view of crack, active shell can prevent the system memory by the direct tool dump, and protect the original entry point of software. Through dynamic spiral transform on this shell method,its security and anticrack capacity of active shell may be enhanced. The software experimental results show that the method can balance its safety and performance.
