We describe a scheme that utilizes pre-shared keys from a quantum key distribution (QKD) system to authenticate site-to-site IPsec tunnels. Testbed measurements indicate sustained TCP connections between the site networks, incurring a throughput reduction of about 30% for approximately a minute during key updates.
