Special Issue Information

Dear Colleagues,

In modern society, various cryptosystems, encompassing both software-based and hardware-based solutions, have been developed to protect private data. As for software-based cryptosystems, various encryption algorithms have been applied in people’s daily lives, where different cryptosystems have been developed for different applications. Furthermore, with the development of quantum computing and optical computing, researchers have proposed hardware-based cryptosystems, offering significantly higher encryption speeds and enhanced security levels.

Despite rising concerns about private data, cryptosystems continue to be a focal point of long-term research. To evaluate the proposed cryptosystems, it is essential to investigate various attack methods, such as the rapidly evolving neural network-based techniques, to identify potential vulnerabilities. Additionally, as an emerging technology, hardware-based cryptosystems have garnered considerable research interest. However, their practical applications remain limited and warrant further exploration.

This Special Issue aims to gather the latest advancements and research findings on cryptosystems, emphasizing the development of both software-based and hardware-based methods. We welcome contributions that address encryption algorithms, innovative attack methods, quantum and optical computing advancements, etc.

The exponential growth of multimedia communication necessitates advanced techniques for secure data transmission. This paper details a new data hiding method centered on a predictive voting mechanism that leverages neighboring pixels to estimate a pixel’s value. Secret data are concealed within these predictions via a purpose-built lookup table, and the retrieval process involves re-estimating the predicted pixels and applying an inverse mapping function. Experimental results demonstrate that the proposed method achieves an embedding capacity of up to 686,874 bits, significantly outperforming previous approaches while maintaining reliable data recovery. Compared with existing schemes, our approach offers improved performance in terms of both embedding capacity and extraction accuracy, making it an effective solution for robust multimedia steganography.
