中文摘要：

研究了细颗粒动态污点分析的瓶颈所在，提出一种基于roBDD的细颗粒度离线污点分析方法。实验结果表明该方法能够显著提高细颗粒度污点分析的性能，并减低内存需求，为进一步扩大细颗粒度污点分析的应用提供了途径。

英文摘要：

The bottleneck of fine-grained taint analysis is figured out. A roBDD-based fine-grained off-linetaint analysis approach is proposed. The experiment results show that the proposed approach can significantly improve the performance of fine-grained taint analysis, and reduce the memory usage.
