Abstract: 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.
