Which principle does encryption support in the practice of information warfare?

• A. Maximizing data transparency
• B. Ensuring data confidentiality and security
• C. Fostering data collaboration
• D. Minimizing data redundancy

Answer: (B)

Encryption protects information by turning readable data into ciphertext that only someone with the right key can decrypt. In information warfare, keeping sensitive content secret from adversaries is essential, so encryption directly supports confidentiality and overall security by preventing unauthorized access even if the data is intercepted. When used with proper keys and, often, authentication, it can also help ensure data integrity and verify who sent it. The other ideas don’t fit this purpose. Encryption doesn’t maximize transparency; it hides content to protect it. It isn’t primarily about enabling collaboration, since sharing requires secure key management, which encryption can complicate if not handled correctly. And it doesn’t address data redundancy, which concerns storage efficiency rather than protecting content.
