fc

uint32_t ieee802154_sec_aux_t::fc

frame counter

Definition at line 296 of file ieee802154_security.h.

key_id

uint8_t ieee802154_sec_aux_t::key_id[]

mode

scf

uint8_t ieee802154_sec_aux_t::scf

Security Control field (SCF)

Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 +-----—+-----—+-----—+-----—+-----—+-----—+-----—+-----—+ | security level | key id. mode | fc sup.| ASN | r | r | +-----—+-----—+-----—+-----—+-----—+-----—+-----—+-----—+

security level: one of IEEE802154_SEC_SCF_SECLEVEL_* key identifier mode: one of IEEE802154_SEC_SCF_KEY_* frame counter suppression: basically always zero because we do not support TSCH right now ASN: basically always zero because we do not support TSCG right now
