Differentiate symmetric and asymmetric encryption.
Understand the Problem
The question is asking for the distinctions between symmetric and asymmetric encryption, focusing on their definitions, characteristics, and differences.
Answer
Symmetric encryption uses one key; asymmetric encryption uses two keys.
Symmetric encryption uses a single key for both encryption and decryption, while asymmetric encryption uses two keys—a public key and a private key—to achieve the same purpose.
Answer for screen readers
Symmetric encryption uses a single key for both encryption and decryption, while asymmetric encryption uses two keys—a public key and a private key—to achieve the same purpose.
More Information
Symmetric encryption is generally faster and more suitable for encrypting large amounts of data, whereas asymmetric encryption provides better security for smaller data transactions or key exchanges.
Tips
A common mistake is assuming that asymmetric encryption is always better due to its security advantages; however, the choice depends on the specific use case and need for speed vs. security.
