Full-disk encryption is the process of encoding all user data on an Android device using an encrypted key. Once a device is encrypted, all user-created data is automatically encrypted before committing it to disk and all reads automatically decrypt data before returning it to the calling process. Full-disk encryption was introduced to Android in 4. Caution: Devices upgraded to Android 5. New Android 5. Android full-disk encryption is based on dm-cryptwhich is a kernel feature that works at the block device layer.

Because of this, encryption works with Embedded MultiMediaCard eMMC and similar flash devices that present themselves to the kernel as block devices. You must use bits or more for the key with being optional.

Upon first boot, the device creates a randomly generated bit master key and then hashes it with a default password and stored salt. You can find the default password defined in the Android Open Source Project cryptfs. Note that managed device may be subject to PIN, pattern, or password restrictions.

Encryption is managed by init and vold. Other parts of the system also look at the properties to conduct tasks such as report status, ask for a password, or prompt to factory reset in the case of a fatal error. This allows Android to prompt for passwords, show progress, or suggest a data wipe as needed.

To trigger these actions, the vold. To kill and restart services, the init commands are:. There are four flows for an encrypted device. A device is encrypted just once and then follows a normal boot flow.

Each of the flows are explained in detail below.

I am developing an application that has SQLite database to store personal information that must be protected. What are some ways of protecting these personal data? Additionally, how can a database of a mobile application be protected? The easiest way is to make users unable to access to the Java Class program.

This is the most fundamental way, and it has a variety of specific ways to achieve this. For example, developers can place the key Java Class on the server, clients acquire services by access relevant interfaces of the server rather than access to the Class file directly.

So there is no way for hackers to decompile Class files. But there are lots of applications are not suitable for this protection. For example, Java programs in stand-alone programs are unable to isolate. To prevent Class files from being decompiled directly, many developers will encrypt some key Class files, such as registration number, serial number management and other related classes. Before using these encrypted classes, the program needs to decrypt these classes first, then loading these classes into JVM.

These classes can be decrypted by hardware, or software. Developers often loading cryptographic classes through a customed ClassLoader class Applet does not support customed ClassLoader because of security. Customed ClassLoader will find cryptographic classes first, then decrypt them. And finally loading the decrypted classes to JVM.
