摘　　要：近年来,随着Android应用数量的增长针对Android应用的攻击手段也在不断增加.应用程序重打包这类软件剽窃手段会快速且大量增加Android应用市场中恶意应用程序的数量,这会对Android生态系统的安全构成威胁.Android应用水印作为一种能缓解应用程序重打包威胁的方法,已有研究者提出一些水印方案.而考虑到应用程序水印被破坏后难以验证的事实,本文提出一种采用中国剩余定理构造的可恢复应用程序水印方法,对于被部分破坏的水印仍然能够实现验证.实验结果显示:对于部分被破坏的水印方案仍能有效恢复出完整水印,而且对于用户来说方案亦具有较小的性能开销.In recent year, with the growth of the Android apps, attacks on these apps are also increasing. Software plagiarism （ app repackaging ） will quickly and greatly increase the number of malicious applications in Android markets, which poses a threat to the Android ecosystem security. Watermarking for Android apps can mitigate the threat of app repackaging, some watermarking schemes have been proposed by researchers. And considering the fact that it is difficult to verify damaged watermarking,a recoverable watermarking scheme is proposed for Android apps with Chinese Remainder Theorem, for part of the destroyed watermark can still achieve validation. The experiments demonstrate that the proposed scheme for the part of the damaged watermark can still effectively recover the full watermark, but also introduces a small performance overhead to users.
