You can use cryptography to protect IP and to prevent cloning of microchips
even if they get reverse-engineered, but the cipher would have to possess
special properties similar to those of VEST ciphers (see
http://www.ecrypt.eu.org/stream/vestp2.html), like support family keying to
make every ASIC chip implement different secret but secure logic, etc.
eBeam, lasers and other technologies are available for that. ECC and other
standard ciphers can't possibly do that.
