Analysis And Research Of System Security Based On

3 What is Android? Android is a software stack for mobile devices that includes an operating system, middleware and key applications.

Android SDK Uses Java programming language Planned to run on different types of devices.

Android platform is based on Linux technology. Composed of OS, user interface and application components. Its issuance breaks the monopoly status of Microsoft windows mobile OS and Nokia’s Symbian OS. Allows anyone to develop him own applications. User is likely to download and install malicious softwares written by software hackers.

Android Platform Architecture Android has built in tools. Android platform composed of Linux kernel, system libraries, android run time, application framework and so on five parts.

Linux kernel Android relies on Linux 2.6 version It provides core system services security,memory management, process management, network group, driven model. The core part is equivalent to an abstract level between the hardware layer and other software in the systems.

Libraries Android includes a set of C/C++ libraries. Android’s core libraries provide most of the function to the Java class libraries.

Android runtime Android runtime consists of two components. First, a set of core libraries. Second, the Virtual machine Dalvik. Java programs are received and translated by the VM Dalvik. Applications will be encapsulated in Dalvik. A VM is available for each and every program even if some programs are running in parallel.

Application Framework An application framework is a software framework that is used to implement a standard structure of an application for a specific OS. Any application can publish its own features. These functions can be used by any other application.

Applications Applications are written in Java programming language. The Android SDK tools compile the code into an android package,an archive file with a.apk suffix. The android software platform come with a set of basic applications. These applications can run simultaneously.

Important Features Application framework Dalvik VM Integrated browser Optimized graphics SQLite Media support GSM telephony Bluetooth,EDGE,3G and WiFi Camera,GPS,compass and accelerometer Rich development environment.

Android System Security In the default settings, no application has permission to perform any operations that would adversely impact other applications, the OS, or the user. Android’s security mechanism is mainly reflected in 2 aspects:Android system security and data security.

Android system security protection Android system safety inherited the design of Linux in the design ideology. In practice, each Android application runs in its own process. In the OS, each application runs with a unique system identity. Most of the security functions are provided by the permission mechanism. Permission can be restricted to particular specific process operations.

Android data security protection Android is privilege separated. Data security mainly relies on software signature mechanism.

It uses AndroidManifest.xml file When specified software services are called,the system first checks this file. To make use of protected features of the device, one must include in AndroidManifest.xml,one or more tags declaring the permissions.
