Covert communications refer to the practice of sending and receiving information in a discreet or hidden manner to prevent detection by unauthorized parties. This research area focuses on developing techniques and methods for encoding, transmitting, and decoding messages in such a way that they are not easily intercepted or understood by unintended recipients. This field is particularly important in fields such as cryptography, cybersecurity, and intelligence gathering, where the secrecy and confidentiality of information are paramount. Researchers in this area often explore a range of communication channels, encryption algorithms, steganography techniques, and other methods to ensure the covert and secure transmission of data.
