Explanation:

What is Computer Network Security?

The security of a computer network can be implemented in a variety of ways. For network transmissions to be secure, privacy, message integrity, authentication, and non-repudiation are required properties.

A privacy method is a way of transmitting data with the highest level of protection. It is only possible for the sender and intended receiver to understand a message. It involves two methods of encrypting and decrypting the data.

What are Encryption and Decryption?

An Encryption method converts information into a form that cannot be understood by others and sends it over the network. Data in this form is known as encrypted data or cipher text.

The Decryption process is the reverse operation of encryption. This process restores the original form of encrypted data. The receiver is responsible for this.

Given:

Person X received an encrypted message and wants to convert it to the actual message. So, he should use the decryption method.

Answer 2

Answer:

The technique he should use is called Decryption.

Explanation:

Decryption

Encryption and decryption are collectively called Cryptography. And they are used to cipher and decipher the normal text that is transferred during digital communication.

When a message is transmitted after the encryption it becomes the cipher text. And the cipher text cannot be read and understood until it is changed in the normal text form.

For doing so, we use the decryption technique.  Generally, a private key is used for performing the decryption and it is only known to the recipient of the message.

Without having the private key to the decryption, the message cannot be transformed into normal text. It saves the message from being read by an unauthorized user.
