An efficient image encryption algorithm based on S-box and DNA code

Abstract

In order to ensure the security of image information transmission, a new image encryption algorithm is proposed based on S-box and DNA coding theory. Through the construction of the dynamic S-box, the key space of the encryption algorithm is enlarged, and the encryption process is more flexible. The flexibility of DNA encoding allows for a larger key volume and higher security in image encryption. Experimental results show that the encrypted image gray level distribution is uniform, the correlation between adjacent pixels is lower, the encryption effect is good, and it has good security.
