Which statement describes the effect of key length in deterring an attacker from hacking through an encryption key?
- The length of a key will not vary between encryption algorithms.
- The length of a key does not affect the degree of security.
- The shorter the key, the harder it is to break.
- The longer the key, the more key possibilities exist.
Answers Explanation & Hints:
While preventing brute-force attacks and other forced decryption concerns, the longer the key length, the harder it is to break. A 64-bit key can take one year to break with a sophisticated computer, while a 128-bit key may take 10 19 years to decrypt. Different encryption algorithms will provide varying key lengths for implementation.
