摘要

Android system since its introduction, with regard to the obvious advantage of the gradual expansion of market share. Android is an open system, much favored by developers, its security is essential. Studied the Android system user ID mechanism, an application signature mechanism, isolated sandbox security policy mechanism ,analyzed Android security risks exist in terms of hardware, Linux kernel and itself permission mechanism.%Android系统自推出以来，就以明显的优势逐渐扩大市场占有份额。Android是一个开放性的系统，备受开发者的青睐，其安全性至关重要。研究了Android系统的用户ID机制、应用程序签名机制、沙箱隔离机制等安全策略，分析了它在硬件方面、Linux内核方面及Android自身权限机制方面存在的安全隐患。
