What does CCI stand for in communications terminology?

CCI in communications terminology stands for Controlled Cryptographic Items. This term refers to specific items that are used in the cryptographic processes of various secure communications systems. These items are critical components in ensuring the confidentiality, integrity, and authenticity of transmitted information. They are managed under strict guidelines and protocols to prevent unauthorized access and possible security breaches.

The significance of CCI lies in its role within military and government communications, where secure transmission of data is paramount. It's imperative that controlled cryptographic items are safeguarded and accounted for, given their importance to national security and military operations.

In contrast, the other options, while seemingly relevant to communications, do not accurately define CCI in the context of cryptography and secure communications practices.
