Method and system for setting up a secure environment in wireless universal plug and play (UPnP) networks

The invention describes a method of setting up a secure environment in wireless Universal Plug and Play (UPnP) networks, comprising a UPnP security console and UPnP controlled devices defined in the UPnP Device Security specification, wherein the entry of information concerning the UPnP security bootstrap as required in the UPnP Device Security specification (particularly an initialization public/private key pair) into the devices is realized via a short-range key transmitter (SKT). A special user-friendly implementation of the UPnP TakeOwnership procedure renders any user interaction other than entering information from a SKT into the devices superfluous. The invention further describes a security system for wireless UPnP networks, comprising a short-range key transmitter (SKT), a security console and a controlled device as defined in the UPnP device security specification.
