Symmetry and Asymmetry in Information Security and Network Security

This Reprint presents a curated collection of cutting-edge research exploring the dual roles of symmetry and asymmetry within the critical domains of information security and network security. The included contributions delve into how symmetric and asymmetric properties manifest in hidden patterns, covert communication channels, and data hiding techniques. By analyzing these structural characteristics, the works included in this Reprint provide valuable insights into the design of more robust, secure, and undetectable network data hiding methods. The collection examines how understanding and configuring the symmetry of hidden patterns can enhance security properties such as robustness, capacity, and undetectability, ultimately contributing to the advancement of practical network security solutions.
