What is the difference between symmetric and asymmetric encryption in cybersecurity?

Symmetric encryption uses the same key for both encryption and decryption, while asymmetric encryption uses a pair of keys: a public key for encryption and a private key for decryption.

When to use Symmetric Encryption:

• In situations where speed and efficiency are crucial, symmetric encryption is preferred.
• It is commonly used for encrypting large amounts of data or for secure communication between known parties.

When to use Asymmetric Encryption:

• Asymmetric encryption is ideal for secure communication between unknown parties where key exchange is required.
• It is often used for digital signatures, secure email communication, and securing online transactions.

Overall, the choice between symmetric and asymmetric encryption in a secure communication system depends on the specific requirements of the system and the level of trust between the communicating parties.
