Native encryption was not available in the Android operating system before Android 3.0, although some vendors may have developed other methods of supporting encryption on certain devices. The native operating system support for encryption was added in Android 3.0 and is based off Linux dm-crypt [4]. The standard encryption at that level was 128 AES while devices running on the Android 4.2 software now support AES-256 bit encryption [5]. Encryption requires the device to have a PIN or password enabled on the device. The PIN or password may not be disabled as long as the device is encrypted. Unlike other mobile operating systems such as iOS, Android does not currently have a hardware based encryption system requirement, which might be required by some organizational policies.
