Cracking the encryption: Parallel computing with molecular finite-state automata and fluorescently labeled DNA molecules has been used to decipher two different images encrypted onto a single DNA chip (see picture). The images were deciphered by a mixture of input molecules that were processed by biomolecular automata, a strategy that potentially offers a huge diversity of encrypted images.
