CompTIA Security+ (SY0-601) — Question 31

Which of the following will increase cryptographic security?

Answer options

• A. High data entropy
• B. Algorithms that require less computing power
• C. Longer key longevity
• D. Hashing

Correct answer: A

Explanation

High data entropy is crucial for cryptographic security as it ensures greater randomness in keys, making them harder to predict and attack. While algorithms that require less computing power may be efficient, they could compromise security. Longer key longevity can be beneficial, but without high entropy, even long keys can be vulnerable. Hashing is important for data integrity but does not directly enhance the security of keys.
