CompTIA Security+ study material · question 557 of 611

Why can a protocol using only static long-term keys not provide forward secrecy?

• Security architecture
• Cryptography

1. Static keys are shorter than ephemeral ones
2. Static keys cannot be stored in hardware
3. Static keys cannot be validated by a certificate authority
4. The same key protects every session, so compromising it exposes all recorded traffic
