Certified Information Systems Security Professional (CISSP) — Question 286

Which of the following is the MOST significant key management problem due to the number of keys created?

Answer options

• A. Exponential growth when using symmetric keys
• B. Exponential growth when using asymmetric keys
• C. Storage of the keys require increased security
• D. Keys are more difficult to provision and revoke

Correct answer: A

Explanation

The correct answer is A because symmetric key algorithms require a unique key for each pair of users, leading to an exponential increase in the number of keys needed as the number of users grows. Options B, C, and D address valid concerns in key management but do not represent the most significant issue related to the sheer quantity of keys generated.
