The security should be commiserate with the value of the assembly.
One customer mechanically removed any programmed device before it left the
building even it it destroyed the PCA, +$30k each.
Another added iron oxide to the potting to obscure the PCA.
If the device ends up intact in the hands of someone willing to spend the
time and money to reverse engineer it. It will be reverse engineered.
Using fake counterfeit chips, loops that erase programs, obscuring schemes,
highly engineered customised devices can all be defeated. What is is
worth?
There are legendary stories of a number of reverse engineered devices.
Including PCB's with poorly incorporated EC's on the original showing up in
the counterfeitt.
Is there a way to keep the device out of the unintended hands?
Larry is exactly right. If time and money exist to do the work, then the
reverse Engineering will happen.
