title: A theoretical application of selectable markers in bacterial episomes for a DNA cryptosystem.
abstract: A theoretical model utilizing the principle of selection for the purposes of DNA cryptography is proposed. A method to enhance the security of DNA cryptosystems that utilize polymerase chain reaction primer keys is presented. Double-encryption systems--encryption systems that have two keys--like the cryptosystem advanced in this paper, are generally more secure than systems that have one key. Two problems with this model are also discussed, and a hypothetical solution to the most major problem is proposed. The chief advantage of this DNA cryptosystem over other DNA cryptosystems is that it has, in theory, two equally secure keys an intruder must break through in order to access a secret message. No experimental analysis has been conducted by the author regarding any of the theoretical methods proposed in this paper.
