secure communications
Coded information exchange
Secure communications are exchanges of information protected from interception or tampering by unauthorized parties.
The term spans encrypted messaging apps, military radio channels, and diplomatic cables.
In practice, secure communications involve both technology (encryption, secure networks) and protocol (need-to-know access, authentication): All sensitive discussions should go through secure communications channels.
