摘要/Abstract

摘要： 总结了软件迷乱技术的发展现状，提出一种在分布式环境下利用并发进程的局部状态构造分布式不透明分支、利用进程间的通信模式改变局部状态以增强迷乱强度的代码保护方案，对现有的分布式代码迷乱算法做了一定的改进，并对该方案做了性能分析。

关键词: 迷乱变换, 分布式不透明分支, 进程通信

Abstract: After analyzing the software obfuscation technology, a code obfuscation scheme under distributed environments was proposed. The local states of concurrent processes were used to construct the distributed opaque predicates, and the communication patterns between concurrent processes were exploited to update the local states so as to increase the obfuscation strength. The proposed scheme improves the existing algorithms of code obfuscation in distributed systems.

Key words: obfuscating transform, distributed opaque predicate, process communication
