System Architecture

1. User Input

• The system begins with a user uploading medical images for encryption or requesting decryption of encrypted images.

2. Preprocessing

• The uploaded medical images undergo preprocessing to prepare them for encryption.

3. Encryption Process

• AES Encryption:

  • The image data is encrypted using the AES algorithm.

  • The AES key is also encrypted to secure the encryption key itself.

• DES Encryption:

  • The output of AES encryption and the encrypted AES key are further secured using the DES algorithm.

  • The resulting data is stored in Encrypted Image Storage and Encrypted AES Key Storage.

4. Decryption Process

• Request Decryption:

  • The user initiates decryption to retrieve the original image.

• DES Decryption:

  • The DES layer is removed first to decrypt the AES key.

• AES Decryption:

  • Using the decrypted AES key, the original image data is reconstructed.

5. Final Output

• The decrypted image is reconstructed and saved, ensuring it matches the original medical image.
