Current image encryption methods have many shortcomings for the medical image encryption with high resolution, strong correlation and large storage space, and it is difficult to obtain reliable clinically applicable medical images. Therefore, this paper proposes a medical image encryption algorithm based on a new five-dimensional three-leaf chaotic system and genetic operation. And the dynamic analysis of the phase diagram and bifurcation diagram of the five-dimensional three-leaf chaotic system selected in this paper is carried out, and NIST is used to test the randomness of its chaotic sequence. This algorithm follows the diffusion-scrambling framework, especially using the principle of DNA recombination combined with the five-dimensional three-leaf chaotic system to generate a chaotic matrix that participates in the operation. The bit-level DNA mutation operation is introduced in the diffusion, and the scrambling and diffusion effects have been further improved. Algorithm security and randomness have been enhanced. This paper evaluates the efficiency of this algorithm for medical image encryption in terms of security analysis and time performance. Security analysis is carried out from key space, information entropy, histogram, similarity between decrypted image and original image, PSNR, correlation, sensitivity, noise attack, cropping attack and so on. Perform time efficiency analysis from the perspective of time performance. The comparison between this algorithm and the experimental results obtained by some of the latest medical image encryption algorithms shows that this algorithm is superior to the existing medical image encryption algorithms to a certain extent in terms of security and time efficiency.

“…Usually, these two methods are applied together, but this paper focuses on the encryption algorithm of data. Guo et al [5] proposed an image encryption scheme based on fractional-order chaotic time series. The experimental results showed that the key space was large enough to resist brute force attacks and the encrypted image had a random distribution of gray values.…”

The involvement of the Internet in the production of daily life has increased the demand for the security of private data on the Internet. This paper briefly introduced the principles of advanced encryption standard (AES) and data encryption standard (DES) algorithms and then conducted simulation experiments on the two encryption algorithms in a laboratory server. The results showed that both algorithms had excellent sensitivity to plaintext keys, and the sensitivity of the AES algorithm was higher; the encryption and decryption time of both algorithms increased as the file got larger, and the encryption and decryption time of the same algorithm was not much different; the encryption and decryption time of the AES algorithm was less than that of the DES algorithm for the same file, and the time taken to crack the AES-encrypted data by brute force was also much longer; during the transmission of encrypted data, as the data increased, the integrity of the ciphertext decryption by the third-party decreased, and the integrity of the AES algorithm-encrypted file was significantly smaller than that of the DES algorithm-encrypted file when it was decrypted.
