1.  Introduction

   Mobile devices such as laptops, smartphones or tablets have different
   requirements than the traditional fixed devices.  These mobile
   devices often change their network attachment.  They are often
   attached to trusted networks, but sometimes they need to be connected
   to untrusted networks where their communications can be eavesdropped,
   filtered or modified.  In these situations, the classical approach is
   to rely on VPN protocols such as DTLS or IPSec.  These VPN protocols
   provide the encryption and authentication functions to protect those
   mobile clients from malicious behaviors in untrusted networks.

   However, some networks have deployed filters that block these VPN
   protocols.  When faced with such filters, users can either switch off
