Abstract: This paper proposes a new image encryption scheme that uses DNA sequences and Residue number system. The design of this scheme is based on the binary to residue data message conversion, then impeding the message secretly inside the DNA sequence. This merge will be leaded to perform multilayer encryption with different keys to increase the security and more flexibility, with less complexity. As the security is one of the most important issues in communication systems, the evolvement of cryptography and cryptographic analysis are considered as the fields of ongoing research. Thus, a straight forward algorithm that achieves efficiency as multi-layer encryption techniques are implemented.
