This study introduces a novel method for secure image transmission, combining double random-phase encryption with Rivest-Shamir-Adelman encryption. The technique allows partial data decryption for acceptable results, ensuring secure key and image delivery.

Area of Science:

  • Cryptography and Information Security
  • Digital Image Processing
  • Data Transmission

Background:

  • Secure transmission of sensitive data, particularly images, remains a critical challenge.
  • Existing encryption methods may face limitations in efficiency or security robustness.
  • The need for integrated solutions that simultaneously transmit encrypted data and keys is growing.

Purpose of the Study:

  • To develop a novel method for simultaneous transmission of an encrypted image and its decryption key.
  • To enhance the security of image transmission by integrating double random-phase encryption and RSA public-key cryptography.
  • To achieve acceptable decryption results even with partial data retrieval.

Main Methods:

  • Encoding the original image using double random-phase encryption (DRPE).

Related Experiment Videos

  • Encrypting the DRPE key using the Rivest-Shamir-Adelman (RSA) public-key algorithm.
  • Modulating the amplitude of the encrypted image with the RSA-encoded key to create a combined encoded image.
  • Transmitting the single encoded image containing both encrypted image and key data.

    • Main Results:

    • Successful creation of an encoded image carrying both the encrypted image and the encoded key.
    • Demonstration that acceptable decryption is achievable with partial data.
    • Guaranteed secure transmission through the robust RSA cipher system.
    • Simultaneous delivery of encrypted image and its corresponding key.

    Conclusions:

    • The proposed method offers a secure and efficient approach for transmitting encrypted images and their keys simultaneously.
    • The integration of DRPE and RSA encryption provides a robust security framework.
    • The technique's ability to yield acceptable results from partial data enhances its practical applicability in secure communication systems.
