Detailed Description

Layer for implementing link layer security.

NETSTACK_LLSEC sits in between NETSTACK_MAC and NETSTACK_NETWORK protocols. All NETSTACK_MAC protocols invoke NETSTACK_LLSEC.input() for incoming packets. Likewise, all NETSTACK_NETWORK protocols invoke NETSTACK_LLSEC.send(...) for outgoing packets.

The bootstrap function of llsec_drivers can be used to defer the start of upper layers so as to bootstrap pairwise keys. Only contiki-sky-main.c supports this at the moment.
