Wouldn't be a flash stored unique key would be safer for the password
encryption? There's a little inconvenience making every flash image
randomized and the flash read protected, but can be done and cost
could be lower than the DS2401 for volume. And the LPC-DS2401 boundary
is not protected in any way, the number can be sniffed, duplicated and
so on.
