中文摘要：

针对Android智能终端安全问题,构建Android智能终端安全分层体系。首先从远程防盗、生物身份验证和硬件安全模块方面阐述了Android设备安全的安全威胁及保护措施,然后从无线安全网络、病毒传播查杀和防钓鱼攻击说明了Android网络安全的隐患及防范,之后从内核安全、本地库运行时环境安全和应用框架安全角度介绍了Android操作系统安全的研究内容,接着从静态检测和应用行为动态检测、应用加固和应用评估方面展示了Android应用安全的研究成果,接下来着眼于数据本身总结了Android数据的追踪、加密和备份等安全保护技术,最后结合实际需求展望了Android安全未来在安全增强框架、智能应用行为分析等方向的发展。

英文摘要：

Aiming at the security, the layered security system was constructed. Firstly, the devices safety protection based on remote anti-theft, biometric identity verification and hardware security module was expounded. Secondly, network security referring to the wireless security network, virus propagation killing and anti-phishing was illustrated. Thirdly, the OS safety was introduced from the perspective of system kernel, runtime environment and application framework. Fourthly, application security was showed containing the reverse engineering static analysis, behavior dynamic analysis, safety reinforcement and safety assessment. Fifthly, the privacy data protection was summarized including tracking, encryption and backup. Finally, the future development direction was prospected on the security framework and intelligent behavior analysis.
