medium📝 Analysis Q13 of 15
Step-by-Step Solution
Solution:
Step 1: Identify quantum algorithms relevant to factoring
Shor's algorithm is a quantum algorithm designed to factor large numbers efficiently, which classical computers cannot do quickly.Step 2: Match algorithm to RSA vulnerability
RSA security depends on factoring large numbers being hard; Shor's algorithm breaks this assumption, making RSA vulnerable.Final Answer:
Quantum computers use Shor's algorithm which factors numbers quickly -> Option BQuick Check:
Shor's algorithm breaks RSA factoring [OK]
Quick Trick: Shor's algorithm = fast factoring, breaks RSA [OK]
Common Mistakes:
MISTAKES- Confusing Grover's algorithm with factoring
- Thinking quantum computers guess keys randomly
- Assuming brute force is the main quantum method
