Review on DNA Cryptography

As a new encryption method, the DNA cryptography takes DNA as the information carrier, and makes full use of the advantages of DNA molecules, such as ultra-high storage density, ultra-low energy consumption, and the potential of ultra-large-scale parallel computing to realize the cryptographic functions of information encryption, authentication, and signature. In this paper, the current research status of DNA cryptography is reviewed, the encryption and authentication based on the DNA molecule and the analysis of traditional cryptography based on the DNA computing are introduced, and the DNA encryption algorithm based on the DNA origami is discussed. The future development of the DNA cryptography is also prospected.
