Abstract

The integrity and confidentiality of transmitted data are the main requirements of any data security system. To achieve these goals, many techniques have been developed, including cryptography and steganography. Recently, DNA-based steganography has emerged as a very powerful and promising approach to ensure the safety of sensitive information transmitted over an untrusted channel. In this paper, a two-level encryption/decryption scheme combining cryptography and steganography is proposed. First, the plain-text is concealed in a cover image by scattering its letters over randomly selected pixels. Then, the modified image is encrypted by encoding its pixels in a DNA sequence using a symmetric key. Simulations have shown that the proposed scheme is more robust than any other system based on standalone techniques and requires less computing resources.
