Exercise 34

Does a VPN use link encryption or end-to-end? Justify your answer.

Step 1 of 2

VPN uses both Link and End-to-end Encryption

To provide secure remote access to the individual user in a network the infrastructure used is known as Virtual private access (VPN).

The methodology for the communication security which is used for encryption and decryption of all the traffic at both the ends of the communication line is known as link encryption.

The methodology that is used for the confidentiality and integrity of the data which is transmitted by encryption at start point of the communication line and decryption at the end point of the communication line is known as end-to-end encryption.

VPN uses both Link encryption and end-to-end encryption for the security of the data.
