Question

Which type of cryptography uses two mathematically linked keys, one key encrypting the data and the other decrypting the data?

Asymmetric
Encoding
Firewall
Symmetric

Answer 1

Asymmetric.

Step-by-step explanation:

Encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.

Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.

There are two (2) main types of encryption techniques used in cryptography and these are;

I. Symmetric encryption.

II. Asymmetric encryption.

Asymmetric encryption is a type of cryptography which uses two mathematically linked keys, one key encrypting the data and the other decrypting the data. These two keys are generally referred to as a public key and a private key respectively.

This ultimately implies that, a pair of key (two keys) that are different in values is required or needed to make a computer system secured.
