Chemical passwords could lead to unbreakable molecular lock

(Phys.org) —If you're in the business of cracking codes, it would be pretty difficult to break into a security system that you don't even know is there. That's one of the advantages of molecular keypad locks, whose small sizes make them very difficult to detect. As such, these locks are an example of steganography, since not only is the password hidden, but the very existence of the lock itself is concealed. Another advantage of these tiny locks is that, instead of using electronic signals, they use chemical and optical signals that further complicate their cracking.
