Establishing secure channels between a pair of hosts is an attractive way when the direct exchange of important data is required. IPsec provides various security services for traffic at the IP layer so we can use it to establish secure channels between a pair of hosts. However, IPsec is difficult to use because there are many parameters to set up for secure channels, and the configuration is complicated, hence our previous proposal of an automatic configuration method to set up the end-to-end secure channels between a pair of hosts; facilitating the use of IPsec. In this paper, we overview our proposed method and describe its implementation and evaluation. In addition, we show how the IPsec setup for 10 hosts on a host implementing our method is completed within a few seconds or so.
