摘要：DNA Cryptography is one of the speedily growing technologies in the world as unbreakable algorithms, as well as to design and implement more complex and resistant to differential attack crypto algorithms. DNA computing had more speed, minimal required storage, and lower power consumption. DNA cryptography participates well-known cryptographic techniques and the characteristics of DNA. Nowadays, there exist several DNA cryptosystems proposed either as an algorithmic approaches or as an integral part of data secrecy applications. Algorithmic approaches were studied by very few researches that integrate both biological and arithmetic operations to gratify the necessity of system optimality. In addition, DNA cryptosystems provide layered security in applications besides other traditional cryptographic algorithms. This study provides a review of DNA cryptographic techniques and algorithm approaches proposed by recent researchers. This study aims to provide a review of DNA cryptographic techniques, algorithms, and approaches proposed by recent researchers, it aims also used to classify which approaches fulfil most of the evaluation parameters, and which is a lightweight cryptography. Most recent publications on DNA cryptographic approaches were reviewed from 2018 to 2022; using a keyword such as “DNA LWC”, “DNA Encryption” among different scientific databases. The findings of this study showed that most articles on DNA cryptography techniques neither provide complete security analysis nor built on mathematical methods. The researchers mostly demonstrated the proposed system model and tested the approaches using computer simulations. Nonetheless, no DNA computation implantations of the surveyed techniques were carried out. This study will assist researches as a reference for researches in future.
