Groups:

(a) Symmetric Encryption

,

(b) Asymmetric Encryption

• commonly used for securing data in transit.

• requires the sender and receiver to share the same secret key.

• does not require the sender and receiver to share a secret key.

• provides better security compared to symmetric encryption.

• less secure than asymmetric encryption due to the shared key.
