SSC CGL Tier II - 19 Jan 2026 - Shift 1 • Computer • Q146

Which of the following is a limitation of using symmetric encryption for securing communications?

Show answer & explanation

Correct answer: D

Explanation

The correct answer is Option 4, i.e., Key distribution and management become challenging.

In symmetric encryption, the same key is used for both encryption and decryption.

  • The shared secret key must be securely distributed to both sender and receiver
  • If the key is intercepted during transfer, security is compromised
  • Managing many keys in large systems becomes complex

This is known as the key distribution problem.
