Detailed explanation-1: -On an IP-based network, network encryption is implemented through Internet Protocol Security (IPSec)-based encryption techniques and standards. Each message sent is in an encrypted form and is decrypted and converted back into plain text/original form at the recipient’s end using encryption/decryption keys.
Detailed explanation-2: -Encrypting personal data whilst it is being transferred from one device to another (eg across the internet or over wired or wireless connections) provides effective protection against interception of the communication by a third party whilst the data is in transfer.
Detailed explanation-3: -Encryption works by encoding “plaintext” into “ciphertext, ‘’ typically through the use of cryptographic mathematical models known as algorithms. To decode the data back to plaintext requires the use of a decryption key, a string of numbers or a password also created by an algorithm.
