File system encryption

By default, the Android file system is not encrypted. This is an important attack vector on an embedded product. Digi Embedded for Android allows you to encrypt the data partition of your Android device to increase the security level of your system. See System architecture for a visual of the Android system layout.

CAUTION! Only the data partition on your Android device will be encrypted; all other partitions will remain unencrypted.

CAUTION! Use file system encryption only on closed devices. File system encryption is not secure on open devices because the encryption key is secured with a test master key.
