Abstract

Information security plays a vital role in almost every application that we handle in our day-to-day life since the communication needs to be protected in terms of the messages that we send and receive. Thus, cryptography the science of encoding the secret information provides security from being known by the unintended receivers. It ensured confidentiality, integrity, and authentication of messages. To simplify the methodology of traditional cryptography with the usage of genetic concepts lead to the field of DNA cryptography. This chapter gives an insight on various methods so far proposed related to DNA cryptography that involves the characteristics of DNA incorporating the traditional cryptographic techniques and a detailed comparison of these techniques thereby proposing the requirements for an efficient DNA-based cryptographic system. These techniques also include the area of steganography that conceals the message within a cover or a career media to eschew the attacks from the intruders.

Background

Until today, there are so many DNA cryptosystems proposed either as an algorithmic approach or implemented as a part of an application to provide data confidentiality to the application data. Among algorithmic approach there are very few authors who incorporate both the biological and arithmetic operations to satisfy the optimality of the system (Hussain, 2015). Other than that, DNA cryptosystems are used for providing layered security in applications that also includes other cryptographic algorithms like traditional cryptosystems (Raju, 2015).
