Re: 802.15.4 security

Hi Simon,

sorry for taking so long to reply. Unfortunately, there's currently no
actual documentation for the crypto layer (and I probably won't come
around to write any sometime soon), but I have built an application
that works with llsec [1].

The process to set up a crypto config for a network is rougly outlined
in [2] and [3]. There are more options to the crypto layer than are used
there, but the process is pretty much the same: you add a number of
devices you want to securely communicate with, add the keys those
devices will use to communicate, and then set the general parameters
for llsec (like default llsec, enabling the crypto layer and such).

Hope that helps a little,
Phoebe
