International Journal of Academic Engineering Research (IJAER)   Year: 2019 | Volume: 3 | Issue: 1 | Page No.: 1-5 DNA Computing and Its Application to Information and Data Security Field?: A Survey Omar G. Abood, Shawkat K. Guirguis Abstract: The emergence of the research topic of DNA in the field of Information Storage, Security and Cryptography has promised new heights to the field. DNA computing is a novel method of simulating the bio-molecular structure of DNA and computing. The promise it came with was a brand-new mean of data structure and calculation which would provide a brand-new generation for storage and more importantly, security and cryptography due to the wide array of parallelism in DNA. The field of cryptography would thrive if the DNA is properly used as it can realize several security technologies such as Encryption, Steganography, Signature and Authentication through the DNA molecular as information medium. This work presents the broad idea of using the existing DNA cryptosystems which utilize the use of the four DNA symbols (A, T, C and G) that represent the four binary two-tuples (00, 01, 10, and 11). However, the obstacles facing the DNA cryptography systems stand in the influence of Turing in the corresponding theoretical computing model. Where it stands in the theoretical stage, it seems to have the ability to solve major problems regarding the security of systems through cryptography.
