symmetrical and asymmetrical

The two main forms of key encryption are symmetrical and asymmetrical.

The two main forms of key encryption are symmetrical and asymmetrical encryption.

Symmetrical encryption, also known as shared-key or private-key encryption, uses the same key for both the encryption and decryption processes. Both the sender and the receiver share the same key, which they use to encrypt and decrypt the data. This method is comparatively faster and simpler but requires secure distribution of the key.

Asymmetrical encryption, also known as public-key encryption, uses a pair of keys: a public key for encryption and a private key for decryption. The public key is freely available and can be shared with anyone, whereas the private key is kept secret by the owner. When someone wants to send a secure message, they use the recipient's public key to encrypt it, and only the recipient can decrypt it using their private key. Asymmetric encryption provides better security and eliminates the need for secure key exchange but is computationally more expensive than symmetrical encryption.

To determine the terms that describe the two main forms of key encryption, you can review the given options and select the correct one, which in this case is "symmetrical and asymmetrical."
