“…The enormous parallelism and eccentric information capacity available in DNA molecules are used for cryptographic principles such as encryption, authentication, and signature. DNA cryptography based on conventional cryptographic approach consists of key generation, encryption and decryption process [4]. But the differences exist in it from conventional one is we use key sequences in a DNA format like ATCGCCAG.…”

During Communication, Information Encryption plays a very important role. While transmitting data, unusual kinds of attacks may occur. To enhance the security during data transmission, cryptographic techniques are used. Cryptography is thus a study in which the message to be transmitted is converted into unreadable form and then sent so that unauthorized users may not be able to read the information. The information is transformed during a phase called Encryption, before being stored or transmitted, based on a Secret key. To guarantee the privacy and validity of the furtive data, a variety of cryptographic techniques have been developed and researchers are continuously working on it to afford better technique towards information security. Though many algorithms have been developed for hiding the data, biomolecular DNA (Deoxyribonucleic acid) sequences based data encryption seems to be a promising approach for satisfying the current information security needs. In this work, the enormous number of features available in DNA sequences are taken and combined with the well known cryptographic algorithm, the Data Encryption Standard (DES). The proposed technique which combines the features of DNA sequences and the Data Encryption Standard is thus named as NDES (Novel Data Encryption Standard) algorithm. This technique thus enhances the security by conversion, manipulation, substitution, confusion and hence provides complexity.

In a way to minimize the gap between digital computing and DNA computing, it is needed to transfer DNA between the two fields, and to make use of the two technologies in generating ideas of data integrity and information security. One of the critical problems in amino acid analysis is how to establish a digital coding system to better reflect the properties of amino acids and their degeneracy. This paper introduces a method to convert digital data to the form of DNA and then to the form of amino acids using the natural RNA codons distribution on the 20 natural amino acids which preserves their biological properties. The Decoding method also convert the amino acids to a digital form. The method solves the problem of ambiguity that more than one codon correspond to the same amino acid. Applicability and reversibility of the method is proven and successfully implemented.The presented encoding method can serve in DNA computers and biological experiments by representing data in the form of amino acids. This mainly aims at increasing the flexibility of converting data between biological medium and digital medium. Although it does not include the use of secret key but it can also be used as an auxiliary factor in cryptographic and steganographic applications like data integrity and digital signature.

“…Although there are many DNA cryptosystems based on the DNA coding sequence to achieve their purposes, DNASC used DNA chip technology. This novel technology offers many advantages in detecting, reading and extracting DNA data [31]. Lai [26] extended Lu's idea and proposed a DNA asymmetric-key cryptosystem (DNA-PKC) based on novel approaches which used DNA probes and DNA chips (microarray).…”

DNA cryptography is a relatively new paradigm that has attracted great interest in the field of information security. Although there are many problems in DNA cryptography, scientists are trying to solve them because they believe that, with the extraordinary information density and the vast parallelism that are inherent in DNA computers, it is possible to make a secure system. In this study, we primarily focus on modern cryptography, which is based on quantum and DNA cryptography. Furthermore, a novel method to encrypt data by using DNA-based cryptography is discussed. In our study, DNA coding technology is used to convert binary data to DNA strings. Finally, the proposed DNA cryptography algorithm's strength is evaluated based on the properties of DNA strands and probability theories.
