该文提出了一种Android平台环境自适应的安全机制:EAdroid。该机制通过对Android系统内核层和框架层的改造,为用户提供了易用的安全策略的定制方式,使得Android系统框架层与内核层中的安全规则能够根据终端所处的环境上下文进行自适应。测试表明:提出的环境自适应安全机制能够在较少的性能开销下有效地抵御恶意扣费、Root提权攻击,保护用户设备及信息的安全。
This paper describes an environment adaptive security mechanism (EAdroid) for Android platforms which provides a simple way for users or trusted third party institutions to customize the security policy of their Android devices. The system reforms the framework and kernel layers of the Android system and then uses the I.inux Smack security module. The security rules of the framework and kernel layers in this system can adapt to the current environment context. Tests show that this system efficiently protects user devices and privacy against malware with little increase in the overhead.
