What could be considered a limitation of encryption in information warfare?

• A. It requires significant computational resources
• B. It does not require a decryption key
• C. It decreases global data exchange
• D. It simplifies password management for users

Answer: (A)

The main idea being tested is the practical trade-offs of using encryption in information warfare: while encryption protects information, it also demands resources that can limit operations. Encrypting data, especially with strong algorithms and long keys, requires CPU time to perform the math, memory to store keys and cryptograms, and energy to power devices and networks. In fast-paced or resource-constrained environments—think real-time communications, large-scale data flows, or devices with limited processing power—this overhead can introduce latency, reduce throughput, or constrain power budgets. Those performance and resource pressures are the real limitation encryption can pose in warfare scenarios. The other statements don’t capture this constraint. Decryption typically relies on the correct key, so saying decryption doesn’t require a key misstates how encryption works. Encryption isn’t inherently corrosive to global data exchange; it can be implemented with manageable overhead and secure data transfer. And encryption does not inherently simplify password management; in fact, it often adds complexity around key and credential management.
