Abstract
With the growing demand for information security, the need for protecting both images and audio continues to increase. While several multimedia encryption schemes have been proposed, their ability to simultaneously handle both data types with high efficiency and security remains limited, largely due to the distinct structural characteristics of images (spatial correlations) and audio (temporal correlations). This study introduces an integrated solution inspired by the structure of gift box ribbons. We propose a multi-image and audio-compatible encryption algorithm based on a hyperchaotic memristive map and cross-cube confusion. First, images and audio signals were vectorized and fused into three-dimensional cubes, enabling their simultaneous encryption within a unified spatial structure. Next, point-to-point confusion was applied to the entire cube, followed by block-wise confusion, where the specific confusion method was dynamically selected by random sequences. Finally, modular diffusion was performed to obtain the ciphertext, effectively randomizing all data values. Performance tests and security analyses confirmed that all evaluation metrics met the required standards while offering advantages in robustness and encryption speed. This algorithm provides a novel and practical approach for integrated multimedia encryption.
