An autodidact, he wrote mail transfer agents as a teenager, and in the
1990s, after failing at high energy physics, found his calling designing and
building embedded networking products in the security sector. Michael has
built multiple IPsec systems, joining the FreeS/WAN team in 2001, and
founding Xelerance.com in 2003. He has operated many networks, worked on
DNSSEC and root name servers, and built several boutique ISPs along the way.
Starting in 2008 Michael began to work on IoT mesh routing, eventually chairing the IETF ROLL working group for a few years.
Michael has since moved on to the problem of how to securely connect and
control IoT devices too small to have user interfaces. The first of these specifications is RFC8366, with several more in the pipeline.
