基于组合式算法的Android恶意软件检测方法

为解决当前恶意软件静态检测方法中适用面较窄、实用性较低的问题，通过组合式算法筛选出最优分类器，并以此为基础实现了一个检测系统。首先使用逆向工程技术提取软件的特征库，并通过多段筛选得到分类器的初步结果。提出了一种基于最小风险贝叶斯的分类器评价标准，并以此为核心，通过对初步结果赋权值的方式得到最优分类器结果。最后以最优结果为核心实现了一个Android恶意软件检测系统原型。实验结果表明，该检测系统的分析精度为86.4%，并且不依赖于恶意代码的特征。

Android malware detection method based on combined algorithm

In order to solve the problems in applicability and usability of today's static malware detection method, a detection system was implemented by using the optimal classifier selected by a combined algorithm as the core. Firstly, the reverse engineering was used to extract the software feature, then the preliminary results of the classifier was got by multi-stage screening. A classifier evaluation was presented based on minimum risk Bayes. Using the new one as the core, the optimal classifier results was got by assignment. Finally, an Android malware detection system prototype was realized using the optimal results as the core. Experimental results show that the analysis accuracy of the proposed detection system was 86.4%, and does not depend on characteristics of the malicious code.
