CompTIA Security+ (SY0-501) — Question 1011
An administrator is testing the collision resistance of different hashing algorithms.
Which of the following is the strongest collision resistance test?
Answer options
- A. Find two identical messages with different hashes
- B. Find two identical messages with the same hash
- C. Find a common has between two specific messages
- D. Find a common hash between a specific message and a random message
Correct answer: A
Explanation
The correct answer, A, demonstrates the strongest collision resistance because it shows that even with identical inputs, the hashing algorithm produces different outputs. Options B, C, and D do not provide strong evidence of collision resistance; B indicates a flaw since identical messages should always produce the same hash, while C and D do not confirm the uniqueness of hashes across different inputs.
