A method comprising downloading a boot image onto a mobile communication device and generating a device-bound certificate (“DBC”). The DBC preferably comprises an authentication code generated using a hashed message authentication code algorithm and a key specific to the device. The method may further comprise storing the DBC on the boot image, thus binding the boot image to the mobile communication device.
