Abstract

On the Android platform, antivirus software suffers from significant deficiencies. Due to platform limitations, it cannot access or monitor an Android device's file system, or dynamic behavior of installed apps. This includes the downloading of malicious files after installation, and other file system alterations. That has grave consequences for device security, as any app - even without openly malicious code in its package file - can still download and execute malicious files without any danger of being detected by antivirus software. In this paper, we present a proposal for an antivirus interface to be added to the Android API. It allows for three primary operations: (1) on-demand file system scanning and traversal, (2) on-change file system monitoring, (3) a set of basic operations that allow for scanning of arbitrary file system objects without disclosing their contents. This interface can enable Android antivirus software to deploy techniques for malware recognition similar to those of desktop antivirus systems. The proposed measures comply with Android's security architecture and user data privacy is maintained. Through our approach, antivirus software on the Android platform would reach a level of effectiveness significantly higher than currently, and comparable to that of desktop antivirus software.

Android恶意软件识别的反病毒API

在Android平台上，杀毒软件存在明显缺陷。由于平台的限制，它不能访问或监控Android设备的文件系统，或安装的应用程序的动态行为。这包括在安装后下载恶意文件，以及其他文件系统更改。这对设备安全造成了严重后果，因为任何应用程序——即使其包文件中没有公开的恶意代码——仍然可以下载并执行恶意文件，而不会有被杀毒软件检测到的危险。在本文中，我们提出了一个将防病毒接口添加到Android API中的建议。它允许三种主要操作:(1)按需文件系统扫描和遍历;(2)随变化文件系统监控;(3)一组基本操作，允许扫描任意文件系统对象而不泄露其内容。该接口可以使Android杀毒软件部署类似桌面杀毒系统的恶意软件识别技术。建议的措施符合Android的安全架构，并维护用户数据隐私。通过我们的方法，Android平台上的杀毒软件将达到比目前显著提高的有效性水平，与桌面杀毒软件相当。
