Link layer security is implemented as a new netstack layer, which is located in between the MAC and the NETWORK layer. The interface of LLSEC drivers is defined in [llsec.h](llsec.h). Additionally, LLSEC drivers may define a special [FRAMER](../mac/framer.h), which calls the actual FRAMER underneath. By default, the LLSEC driver `nullsec` is used, which does nothing.
# TODO
* Most main files do not call LLSEC.init, yet

`noncoresec` is a noncompromise-resilient 802.15.4 security implementation, which uses a network-wide key. Add these lines to your `project_conf.h` to enable `noncoresec`:
```c
#undef LLSEC802154_CONF_ENABLED
#define LLSEC802154_CONF_ENABLED 1
#undef NETSTACK_CONF_FRAMER
#define NETSTACK_CONF_FRAMER noncoresec_framer
#undef NETSTACK_CONF_LLSEC
#define NETSTACK_CONF_LLSEC noncoresec_driver
#undef NONCORESEC_CONF_SEC_LVL
#define NONCORESEC_CONF_SEC_LVL 1
```
`NONCORESEC_CONF_SEC_LVL` defines the length of MICs and whether encryption is enabled or not.
Setting the network-wide key works as follows:
```c
#define NONCORESEC_CONF_KEY { 0x00 , 0x01 , 0x02 , 0x03 , \
0x04 , 0x05 , 0x06 , 0x07 , \
0x08 , 0x09 , 0x0A , 0x0B , \
0x0C , 0x0D , 0x0E , 0x0F }
```
