Solution

The primary purpose of cryptography in network security is to protect data from unauthorized access. Cryptography is a method of storing and transmitting data in a particular form so that only those for whom it is intended can read and process it. This is done by encrypting the data.

Encryption is the process of converting plaintext into ciphertext, which is a scrambled version of the original data that is unreadable without the correct decryption key.

In the context of network security, cryptography is used to prevent unauthorized users from accessing the data as it is transmitted across the network. This is particularly important in situations where sensitive data is being transmitted, such as financial transactions or personal information.

So, in summary, the primary purpose of cryptography in network security is to protect data from unauthorized access as it is transmitted across a network.
