    Abstract: Some examples relate to a pre-shared key based virtual private network. In an example, a VPN server generates a unique pre-shared key (PSK) corresponding to an identity of a VPN client. The VPN server creates a mapping between the identity and the unique PSK of the VPN client, and stores it in a database. The VPN server shares the unique PSK with the VPN client. In response to receiving an IKE packet comprising an encrypted identity of the VPN client, the VPN server decrypts the encrypted identity of the VPN client from the IKE packet to determine the identity of the VPN client associated with the IKE packet. The VPN server retrieves the unique PSK corresponding to the identity of the VPN client associated with the IKE packet from the mapping stored in the database. The VPN server establishes a VPN connection with the VPN client.
