IT SecurityQuestion 65 of 100
What is the difference between symmetric and asymmetric encryption?
a.Symmetric uses one shared key while asymmetric uses a public/private key pair
b.Symmetric is always weaker than asymmetric
c.Asymmetric does not use keys
d.There is no difference
Explanation
Symmetric encryption uses a single shared key for both encrypting and decrypting data, which is fast but requires securely sharing the key. Asymmetric encryption uses a mathematically linked public and private key pair, allowing secure exchange without sharing a secret key. Many systems combine both for efficiency and security.
