What is VPN?
VPN (Virtual Private Network) is a secure connection between private networks over a public network such as the Internet. In order to keep the data confidential, the traffic and thus the information is sent encrypted over the public network.
The traffic is routed through the tunnel to the TUnet, unpacked, and from there as unencrypted IP traffic to the target computers at the TU or via our connection to the Internet.
The encrypted connection of the users ends at a so-called VPN concentrator (it is said that the encrypted tunnel is terminated at the concentrator).
The main features of VPN are:
The sender encrypts the information before sending it over the network. This means that no one can decipher any information that may have been intercepted.
- Data integrity:
The recipient can verify that the data has not been altered in any way during transmission over the Internet.
- Authenticity of the data source:
The recipient can clearly identify and verify the data source and thus the origin of the information.
