4 Submission January 2014doc.:IEEE 802.11-14/0157r0 Menzo Wentink, Qualcomm CCMP Header Compression Compression of the CCMP header consists of three steps 1.The packet number (PN) is transmitted only partly 2.The transmitted part is combined with Sequence Control (SC) 3.Key ID and Ext IV are omitted CCMP header compression is proposed in combination with the 802.11ah short frame format Slide 4 PN0PN1Rsvd Key ID - Ext IV - Key ID PN2PN3PN4PN5 Current CCMP header 802.11ah short frame MAC header (A3, A4 are optional)

5 Submission January 2014doc.:IEEE 802.11-14/0157r0 Menzo Wentink, Qualcomm 1. Transmit only part of the Packet Number The PN is split into a Base PN (BPN) and a Transmitted PN (TPN) –Transmitted PN = PN0|PN1 - transmitted –Base PN = PN2|PN3|PN4|PN5 - stored –The PN can be reconstructed as BPN|TPN –The TPN rolls over every 2^16 packets the TPN size coincides with sequence control size, but exact size TBD the TPN size should be large enough to avoid frequent BPN sync events Slide 5 PN0PN1PN2PN3PN4PN5 Transmitted PN (TPN) - transmitted with each packetBase PN (BPN) - stored

6 Submission January 2014doc.:IEEE 802.11-14/0157r0 Menzo Wentink, Qualcomm 2. Combine Packet PN with Sequence Control Combining the Transmitted PN (TPN) with Sequence Control causes that the Packet Number becomes unique per TID –The TID is included in the Nonce, so the Nonce is still unique Technically the TID does not even have to be included in the Nonce, because there is a replay counter per TID –The Packet Number now has to be fixed when the Sequence Number is determined This is not considered to be a problem –The Fragment Number (FN) effectively reduces the PN space with 4 bits TPN range effectively becomes 2^12 when no fragmentation is used Slide 6 PN0PN1 FN (4b) SN (12b) = Transmitted PNSequence Control

7 Submission January 2014doc.:IEEE 802.11-14/0157r0 Menzo Wentink, Qualcomm 3. Omit Key ID and Ext IV Ext IV is always 0 for CCMP, so it can be omitted The Key ID is typically fixed for unicast traffic, but it can change for group traffic –when the GTK is rekeyed and it is not possible to delay certain group traffic during this process, normal frames (with a Key ID) can be used to transmit such group frames Slide 7
