Question

What are the differences between symmetric and asymmetric key systems?

Answer 1

Symmetric does not use a key, and asymmetric makes use of keys.

Symmetric is one way, and
asymmetric is a two way function.

Symmetric uses one key to both encrypt and decrypt, and asymmetric uses two keys, one to encrypt and another to decrypt.

 Symmetric encryption is strong and
 asymmetric encryption is weak.

hope it helps

Answer 2

The basic difference between symmetric and asymmetric key cryptography is that symmetric encryption requires the same key to be encrypted and decrypted. In the other hand, asymmetric encryption uses a key for encryption and uses another key for decryption. A single key for both decryption and encryption.
