“…For the second type of image encryption methods, the DNA coding algorithm proposed by Adleman [12] in 1994 has provided a new development idea and technology for cryptography and been widely in image encryption field because of its low-consumption and high-density information storage capacity. DNA coding is one of the fastest developing new technologies in the field of genetic research [13].…”

With the international development of the medical service informatisation, medical information sharing has become the key standard to measure the degree of medical informatisation. In this process, it is important to ensure the security of patients' medical information such as patients' records, examination reports, images and so on. In this article, an image encryption scheme based on Secure Hash Algorithm 3 (SHA‐3), DNA coding and high dimensional chaos system is proposed to promote the security level of medical images in information sharing processes such as over the network. First, SHA‐3 algorithm is used to calculate the hash value of the input image, and the result is taken as the initial value of the hyper‐chaotic system. Second, the intensity value of the input image is converted into a serial binary digital stream. Third, the pseudo‐random sequence generated by a 4‐dimensional hyper‐chaotic system is used to perturb the bit stream globally so as to achieve the purpose of hiding the effective information of the input image. During the operation of hyper‐chaotic sequence and DNA sequence, algebraic and complementary operations are performed on DNA encoding values to enhance encryption performance. Finally, simulations have been applied on an open‐source medical image database, and the results demonstrate obvious encryption effectiveness and high security level of the proposed encryption algorithm in the robustness of noise and clipping attacks.
