Help¶

This option will expose the hardware AES encryption from CC2520. Such feature should not be used for anything but 802.15.4 security. The crypto device exposed will only support synchronous CCM operation.

Direct dependencies¶

NET_L2_IEEE802154_SECURITY && IEEE802154_CC2520 && IEEE802154

(Includes any dependencies from ifs and menus.)
