NAME

struct_ieee80211_key_conf - key information

SYNOPSIS

 struct ieee80211_key_conf {
   enum ieee80211_key_alg alg;
   u8 icv_len;
   u8 iv_len;
   u8 hw_key_idx;
   u8 flags;
   s8 keyidx;
   u8 keylen;
   u8 key[0];
 };

MEMBERS

alg

The key algorithm.

icv_len

The ICV length for this key type

iv_len

The IV length for this key type

hw_key_idx

To be set by the driver, this is the key index the driver wants to be given when a frame is transmitted and needs to be encrypted in hardware.

flags

key flags, see enum ieee80211_key_flags.

keyidx

the key index (0-3)

keylen

key material length

key[0]

key material. For ALG_TKIP the key is encoded as a 256-bit (32 byte)

DESCRIPTION

This key information is given by mac80211 to the driver by the set_key callback in struct ieee80211_ops.

DATA BLOCK

- Temporal Encryption Key (128 bits) - Temporal Authenticator Tx MIC Key (64 bits) - Temporal Authenticator Rx MIC Key (64 bits)
