DOT11_KEY_ALGO_CCMP structure (windot11.h)
Syntax
typedef struct DOT11_KEY_ALGO_CCMP {
UCHAR ucIV48Counter[6];
ULONG ulCCMPKeyLength;
UCHAR ucCCMPKey[1];
} DOT11_KEY_ALGO_CCMP, *PDOT11_KEY_ALGO_CCMP;
Members
ucIV48Counter[6]
The initial 48-bit value of the AES-CCMP Packet Number (PN), which is used for replay protection. For more information about the PN, see AES-CCMP.
ulCCMPKeyLength
The length, in bytes, of the AES-CCMP key material in the ucCCMPKey array. If the authentication and cipher key derivation is performed by the operating system, this member will always have a value of 16.
ucCCMPKey[1]
The AES-CCMP key material.
Remarks
When the AES-CCMP key is created, the 802.11 station must maintain separate PN counters for the key for the send and receive path. The station must initialize the PN counters in the following way:
- Initialize the PN counter used for the receive path to the value specified in the ucIV48Counter member.
- Initialize the PN counter used for the send path to any value.
