RCS (Radio Communications Security)

Radio Communications Security (RCS) involves protecting wireless transmissions from unauthorized access, eavesdropping, or tampering. It uses encryption and secure protocols to ensure that messages sent via radio waves are only accessible to intended recipients. RCS is essential for maintaining confidentiality and integrity in military, governmental, and critical communication systems, preventing adversaries from intercepting sensitive information. Techniques include frequency hopping, secure key management, and encrypted channels, all designed to make radio communications more resilient against security threats while allowing authorized parties to communicate reliably and securely.
