Note that capture shown below has taken when AG2 connecting to different AP advertising same SSID, CWAP-TEST.ДЄP respond with Association Response message with status code unsuccessful ( failure code 43 вЂ“ Invalid AKMP) Once exchange two open Auth frames, it is sending Association Request with AKM as PSK ( 00-0F-AC:2). Since it is not supporting WPA3 ( with v4.0 firmware), it wonвЂ™t able to connect. Here is when AirCheckG2 is trying to connect to this SSID.

In this method, there is no way of decrypting that traffic, even if SSID password being compromised.

Once encryption keys derive, all data traffic will be encrypted. Then AP & STA go through 4 way handshake to derive its encryption keys. You will see вЂњsuccessfulвЂќstatus in association response. Note that AKM 00-0F-AC:8 is used to indicate SAE is in use. Once SAE message exchange complete, client send Association Request. Here is the вЂњConfirmвЂќ message goes from AP to STA. It includes a hash of the key generated where other party can verify it once received. Through вЂњConfirmвЂќ messages both side confirm that they have same keys. Commit message contain Grooup ID, a Scalar & an element (FFE) that is produced using PWE (equivalent to public key)ДЄP also send an authentication frame that include Group Number & its pubic key (FFE) Her is the first Authentication frame details. A group is selected and minimum ECDH-Group 19 support (256 bit) must be there for interoperablity.ДЇirst two auth messages are SAE message type вЂњ Commit or 1вЂќ (Auth Seq No 1) and other two are SAE message type вЂњ Confirm or 2вЂќ (Auth Seq No 2). Prior to exchange SAE auth messages, both side generate a secret element PWEВ ( Password Element) & two secret values ( rand & mask). Below shows different Auth Algorithm numbers used in WiFi. Note that Authentication Algorithm number is 3, which is used for SAE. If you look at those Authentication frames, you will notice there are 4 frames in total. WPA3-SAE Certification does not require to have FT support. Note that 00-0F-AC:9 also for SAE with FT support. Highlighted AKM is the one seen in our capture ( 00-0F-AC:8 which is SAE). Table below shown AKM suite defined in IEEE 802.11-2016 standard.

AKM Suite list field contains a series of AKM suite selectors. Highlighted Group Data Cipher Suite, Pairwise Cipher Suite (CCMP-128) and Group Management Cipher Suite (BIP-CMAC-128) used in given BSS in my capture.ДЄKM Suite Count field indicate the number of AKM suite selectors in the AKM Suite list field. When management frame protection is negotiated, the negotiated pairwise cipher suite is used to protect individually addressed robust Management frames, and the group management cipher suite is used to protect group addressed robust Management frames.Д¬ipher Suite Selectors defined in IEEE802.11-2016 standard (table 9.131) shown below. Group Management Cipher Suite вЂ“ cipher suite selector used by BSS to protect group addressed robust management frames. Pairwise Cipher Suit ListвЂ“ contain series of cipher suite selectors that indicate pairwise cipher suites.ДЈ. Group Data Cipher Suite вЂ“ contain cipher suite selector used by BSS to protect group addressed frames.Дў. In RSNE, there are three type of cipher suitesДЎ. Also note that both MFP Required & MFP Capable set to true (In other words management frame protection is mandatory with SAE). If you look at details of a Beacon frame, you will notice AKM Suite is 00-0F-AC:8 (SAE) under RSNE. If you look at the frame exchange,you will see it includes 4 Authentication frames, Association Request, Association Response followed by 4-Way Handshake (M1-M4 messages). Here is a packet capture when client is connecting to above SSID (follow this post to see packets as 802.11 frames). Here is the WLAN security configuration on my SSID. Pls note that following restriction applies when you configure WPA3-SAE in AireOS 8.10.x version. In this post we use AireOS based WLAN configuration to study WPA3-SAE operation. Protected Management Frames (PMF) is mandatory in WPA3-SAE mode.Д¬isco introduced WPA3 support to its AireOS based controllers from version 8.10.x onward (It is 16.12 onward for IOS-XE based controllers). WiFi Alliance also introduced WPA3-SAE Transition Mode which we will look at in a later post.

With WPA3-Personal, PMK is not depend on the password. In WPA2-Personal, PMK is derived from the password hence a major weakness of that mechanism (it is very easy to decrypt WPA2-PSK traffic). It is based on SAE вЂ“ Simultaneous Authentication of Equals, an password based authentication and key establishment protocol initially introduced in IEEE 802.11s for mesh networks.

In this post, we will look at WiFi Alliance WPA3-SAE (also known as WPA3-Personal) to replace WPA2-Personal which is susceptible to offline dictionary attack.
