Alastair Irvine will be presenting on IPsec, which is a cross-platform, network-layer crypto facility built into the TCP/IP stack of all modern operating systems. It was designed for IPv6 but was back-ported to IPv4 many years ago.

One of the ways in which IPsec can be used is "tunnel mode", which is indistinguishable in practice from regular VPNs provided by OpenVPN or Cisco's vpnc client for example.

This presentation will cover the use of IPsec with locally-generated X.509 certificates. I'll describe a Makefile that I wrote that acts as a Public Key Infrastructure (a.k.a. Certificate Authority) facility, allowing a trust framework to be established without relying on passwords or external authorisation. Only someone who has been issued a certificate can connect, and any of these certificates can be revoked on request by adding it to a list on the VPN server.

The strongSwan software is used on the server, and on Linux/Unix clients, but clients on other platforms are supported.
