XML File Encryption

<gs_provision version="1"> <mac>000b82123456</mac> <config version="1">

<P271>0</P271> <P270>Account name</P270>

</config> </gs_provision>

The mac element is not mandatory. It is designed this way because not all provision systems support MAC address. If it is present, the provision program will validate the mac element with the actual MAC address on the device.

The XML configuration file may be encrypted using AES-256-CBC algorithm. The encryption password is defined in P1359 (XML Config File Password) of the configuration file. The encryption may use salt to enhance security. The algorithm to derive the key and IV from a password is the same as the one used by OpenSSL:

The OpenSSL command-line to encrypt the file is as follows:

Openssl enc –e –aes-256-cbc –k password –in config.xml –out cfgxxxxxxxxxxxx.xml

Alternatively, users can also set the XML Config File Password in the web UI of the phone.

Figure 2: Using web UI to define the XML Configuration File Password

When the XML configuration file is encrypted using this method, the phone would only be able to decrypt and parse the file if user set the XML Config File Password in P1349 of binary configuration file or in the web UI.
