Detailed Description

Interface-level security attributes, see section 9.5.

Field Documentation

frame_counter

uint32_t ieee802154_security_ctx::frame_counter

Interface-level outgoing frame counter, section 9.5, table 9-8, secFrameCounter.

Only used when the driver does not implement key-specific frame counters.

key

uint8_t ieee802154_security_ctx::key[16]

Interface-level frame encryption security key material.

Currently native L2 only supports a single secKeySource, see section 9.5, table 9-9, in combination with secKeyMode zero (implicit key mode), see section 9.4.2.3, table 9-7.

Warning

This is no longer in accordance with the 2015+ versions of the standard and needs to be extended in the future for full security procedure compliance.

key_len

uint8_t ieee802154_security_ctx::key_len

Length in bytes of the interface-level security key material.

key_mode

uint8_t ieee802154_security_ctx::key_mode

Frame security key mode.

Currently only implicit key mode is partially supported, see section 9.4.2.3, table 9-7, secKeyMode.

Warning

This is no longer in accordance with the 2015+ versions of the standard and needs to be extended in the future for full security procedure compliance.

level

uint8_t ieee802154_security_ctx::level

Frame security level, possible values are defined in section 9.4.2.2, table 9-6.

Warning

Currently native L2 allows to configure one common security level for all frame types, commands and information elements. This is no longer in accordance with the 2015+ versions of the standard and needs to be extended in the future for full security procedure compliance.
