Abstract
Recent research is focused on the exploitation of DNA-based molecules for data encryption due to their high capacity to store larger volumes of data and lower computation requirements [1, 2]. This study proposes a Hybrid Image Encryption method (HIE) that convolves DNA sequence encoding with the Rivest–Shamir–Adleman (RSA) algorithm to enhance the security of image encryption. The proposed scheme uses small prime numbers to encrypt the image, which is then encoded as a DNA sequence. Subsequently, the encrypted DNA sequence is stored in a physical medium. The encrypted DNA sequence can then be decrypted using the RSA algorithm and the corresponding private key to recover the original image. The results show that using small prime numbers for RSA encryption of an image and encoding it as a DNA sequence can enhance security and reduce computational time.
