This idea fully exploits the configurable logic aspect of the 74aup2g57gm. This idea work similarly to AES encryption. Each configurable logic device would be act as a tumbler preceding the logic device before it. The opens and shorts would determine the resulting logic which would result in an unique code for that message. To further encrypt a GPS Time sync could be added to allow for a more obscure message. To decrypt the device would simply need to be inverted...so a message could be uniquely encoded using a basic ASCII binary representation. The hardware device would be the key for the message. so something like this could be realized. There's probably a patent lurking somewhere within this one.... :-)
