Alternative DNA security using bioJava

Abstract

This paper presents alternative security methods based on DNA. From the alternative security methods available, a DNA algorithm was implemented using symmetric coding in BioJava and MatLab. As results, a comparison has been made between the performances of different standard symmetrical algorithms using dedicated applications. In addition to this, we also present an asymmetric key generation and DNA security algorithm. The asymmetric key generation algorithm starts from a password phrase. The asymmetric DNA algorithm proposes a mechanism which makes use of more encryption technologies. Therefore, it is more reliable and more powerful than the OTP DNA symmetric algorithm. © 2011 Springer-Verlag Berlin Heidelberg.
