Hi Phoebe,
I am having some problems with the 802.15.4 security.
What kernel version/gitref did you last test the 802.15.4 security on?
What level of security are you using? (1-7)
I can then have a look what has changed since and try and debug the
problems I am seeing.
I find if I set the security level to 1,2,3 I get a kernel panic
whenever a packet is sent.
If I set the security level to 4 the packets sent are corrupt.
If I set the security level to 5-7 wireshark decodes the packets as MIC
check failed.
Regards
Simon

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

What is the status of the crypto-layer? I can see a lot of crypto
functionality in the mac layer but I can't work out how to setup the
keys and enable encryption/authentication. Will this be part of the
wpan-tools?
