A few DNA-based security techniques

Biological systems have been a rich source of inspiration for computer security professionals. In this paper we briefly review some of the security proposals inspired by DNA. By looking at the procedures of genetic information processing we propose a few techniques that can be applied to protect information, including a secure communication protocol inspired by primer-based gene recognition, DNA-based key distribution inspired by DNA base sequence complementarities, DNA-based steganography with the chemical information of the bases co-inspired by the LSB-based image steganography, and steganography with intronization inspired by the intron removal process in the central dogma of biology. The security of the proposed techniques is briefly analyzed.
