Abstract

In today's era, the traditional cryptographic methods are not sufficient to provide security to the data. Everyone wants to secure their data whether the data is bank transaction, email transaction, personal data or the data related to work. To provide security to the data, DNA cryptography emerges as a new field. DNA cryptography is a new branch of cryptography. It provides security to the data by converting the data in the form of DNA sequence. A lot of research has been done in the area of this cryptography. It consists of various stages like converting data in the form of DNA, reverse conversion, various methods of encryption etc. Various methods of encryption are present until now in the DNA cryptography. But the problem with them is that they all have more emphasis on biological encryption methods. There is a need of methods which make use of simple biological methods and complex binary or other number system encryption. In this paper, the authors are proposing a new algorithm for providing security to the data at two levels. The authors propose a parabolic transposition in a circular arrangement of data. In the proposed algorithm, data is arranged in a circular way. The number of rows and columns acts as a key for binary encryption. For encrypting the DNA sequence, the authors convert the DNA sequence into amino acid. This amino acid sequence will act as a cipher text and send to the receiver through the open environment. The proposed algorithm is a type of block cipher. It is a transposition cipher. It changes the position of data for binary encryption.

2. Dna Cryptography

For understanding the DNA cryptography, the researcher must know about the DNA. DNA stands for Deoxyribo nucleic acid. It is the basic genetic element of every living organism whether it is a small organism or a human being. It is a blueprint of living organism. It is unique for everyone. It consists of four nucleotides i.e. adenine (A), thymine (T), cytosine (C) and guanine (G). DNA forms the double helical complementary structure. This structure was identified by James Watson and Francis Crick (Watson et.al., 1953).

DNA cryptography is a new branch of cryptography. DNA cryptography provides the security by converting data in the DNA sequence. It provides security at the two levels. It provides security at the binary level by using traditional cryptographic method or mathematical operations and provides security at the DNA sequence level using biological operations like complement, transcription and amino acid conversion etc. This science was introduced in 1994 by Dr. Leonard M. Adelman of the University of South California to solve the complex mathematical problem (L. Adelman, 1994). It takes binary data and converts it into DNA sequence and then encrypts it. The converted DNA sequence acts as a plaintext in DNA cryptography. DNA cryptography is further divided into three sub branches:

  • Asymmetric DNA Cryptography

  • Symmetric DNA Cryptography

  • Pseudo DNA Cryptography
