Enhanced DNA Computing Biological Model for Implementing a Covert Communication Channel
DNA computing, also known as molecular computing,is a new approach to massively parallel computation. It harnesses the enormous parallel computing ability and high memory density of biomolecules,which brings potential challenges and opportunities to traditional cryptography. DNA Steganography is a new field arising with DNA computing research in recent years. Most of the techniques that were implemented were based on modulating a media file to hide the information required to be transmitted. If the transmission is rather continuous in time, one may refer to the technique as a covert communication channel between two parties.Various methods of advanced steganalysis techniques, with varying degrees of success, were developed to detect the existence of such hidden messages in a media file.
In this work, we present an alternative approach to hiding data in text files. We use different DNA-operations and the message is embedded within a vector sequence. The proposed method covers all the words of English Dictionary for framing a message.
