Abstract
A virtual private network (VPN) client receives data including a pre-shared key (PSK). The VPN client decrypts the data based on a short-term key pair to obtain a ciphertext. The VPN client then decrypts the ciphertext based on a short-term quantum-resistant key pair to obtain the PSK. A VPN tunnel is then established between the VPN client and a VPN server based on the PSK.
