GUI - Circular Shifts for Efficient Chaotic Image Encryption

GUI imoplementing a chaotic encryption algorithm

The GUI implements the chaotic encryption algorithm proposed in the following work:

Moysis, L., Lawnik, M., Alexan, W., Goudos, S. K., Baptista, M. S., & Fragulis, G. F. (2025). Exploiting Circular Shifts for Efficient Chaotic Image Encryption. IEEE Access.

https://ieeexplore.ieee.org/document/11009169

Please cite this work if you use the code below.

The work is open access, so you can find information about the algorithm and its steps in the pdf.

The encryption code is also available in: https://uk.mathworks.com/matlabcentral/fileexchange/181195-circular-shifts-for-efficient-chaotic-image-encryption?s_tid=srchtitle

The algorithm uses the DataHash function by Jan, from:

https://uk.mathworks.com/matlabcentral/fileexchange/31272-datahash

The GUI works as this:

Encryption:

- Load the image you want to encrypt.

- Press Encrypt and Save key.

- The image in encrypted, and you get automatically prompted to save the encryption key in a .txt file.

- You can then save your encrypted image.

Decryption:

- Load the image you want to decrypt.

- Load the decryption key.

- Choose the Decryption option.

- You can now save your decrypted image.

Remember, save the images in png format.
