Certified Information Privacy Technologist (CIPT) — Question 29

What is the potential advantage of homomorphic encryption?

Answer options

• A. Encrypted information can be analyzed without decrypting it first.
• B. Ciphertext size decreases as the security level increases.
• C. It allows greater security and faster processing times.
• D. It makes data impenetrable to attacks.

Correct answer: A

Explanation

The correct answer is A because homomorphic encryption enables computations to be performed on ciphertext, allowing data analysis without the need for decryption. Option B is incorrect as increasing security levels typically results in larger ciphertext sizes. Option C is misleading since while it enhances security, it may also lead to slower processing times due to the complexity of operations on encrypted data. Option D is inaccurate, as no encryption method can guarantee absolute impenetrability against all attacks.
