An encryption scheme based on DNA microdots technology

Abstract

As a new research area of information security, DNA cryptography has achieved rapid advancements over recent years. It has been demonstrated that data hiding and encryption can be realized based on DNA digital encoding and microdots steganographic techniques. Here we present a more secure encryption scheme utilizing DNA microdots. It is noteworthy that the scheme achieves double concealing, which combines the properties of traditional cryptography and DNA microdots. The security of the scheme is analyzed from several aspects as well. Finally, the simulation proved a strong confidentiality of the encryption scheme.
