Configuring WLAN security

About WLAN security

WLAN security mechanisms include Pre Robust Security Network Association (Pre-RSNA), 802.11i, and 802.11w.

Pre-RSNA defines the original security mechanism, which is vulnerable to security attacks. To enhance WLAN security, 802.11i was introduced, but it encrypts only WLAN data traffic. Based on the 802.11i framework, 802.11w offers management frame protection to prevent attacks such as forged de-authentication and disassociation frames.

Pre-RSNA mechanism

The pre-RSNA mechanism uses the open system and shared key algorithms for authentication and uses WEP for data encryption. WEP uses the stream cipher RC4 for confidentiality and supports key sizes of 40 bits (WEP40), 104 bits (WEP104), and 128 bits (WEP128).

Open system authentication

Open system authentication is the default and simplest authentication algorithm. Any client that requests authentication by using this algorithm can pass the authentication.

Open system authentication uses the following process:

1.     The client sends an authentication request to the AP.

2.     The AP sends an authentication response to the client after the client passes the authentication.

Figure 1 Open system authentication process

Shared key authentication

Shared key authentication uses a WEP key for the AP and client to complete authentication.

Shared key authentication uses the following process:

1.     The client sends an authentication request to the AP.

2.     The AP randomly generates a challenge text and sends it to the client.

3.     The client uses the WEP key to encrypt the challenge text and sends it to the AP.

4.     The AP uses the WEP key to decrypt the challenge text and compares the decrypted challenge text with the original challenge text. If they are identical, the client passes the authentication. If they are not, the authentication fails.

Figure 2 Shared key authentication process

802.11i mechanism

IMPORTANT

IMPORTANT:

802.11i requires open system authentication for link layer authentication.

Security modes

The 802.11i mechanism (the RSNA mechanism) provides WPA and RSN security modes. WPA implements a subset of an 802.11i draft to provide enhanced security over WEP and RSN implements the full 802.11i.

AKM

The 802.11i mechanism uses the following authentication and key management (AKM) modes for authenticating user integrity and dynamically generating and updating keys:

·     802.1X—802.1X performs user authentication and generates the pairwise master key (PMK) during authentication. The client and AP use the PMK to generate the pairwise transient key (PTK).

·     Private PSK—The MAC address of the client is used as the PSK to generate the PMK. The client and AP use the PMK to generate the PTK.

·     PSK—The PSK is used to generate the PMK. The client and AP use the PMK to generate the PTK.

Authentication

802.1X authentication is more secure than PSK authentication. For more information about 802.1X authentication, see "Configuring WLAN user access authentication."

PSK authentication requires the same PSK to be configured for both an AP and a client. PSK integrity is verified during the four-way handshake. If PTK negotiation succeeds, the client passes the authentication.

Key management

Key management defines how to generate and update the PTK and group temporary key (GTK). The PTK is used in unicast and the GTK is used in multicast and broadcast.

PTK and GTK

·     PTK structure

¡     EAPOL-Key Confirmation Key (KCK) is used to verify the integrity of an EAPOL-Key frame.

¡     EAPOL-Key Encryption Key (KEK) is used to encrypt the key data in the EAPOL-Key frame.

¡     Temporal Key (TK) is used to encrypt unicast packets.

·     The GTK includes the TK and other fields. The TK is used to encrypt multicast and broadcast packets.

EAPOL-Key packet

The IEEE 802.11i protocol uses EAPOL-Key packets during key negotiation.

Figure 3 EAPOL-Key structure

Table 1 EAPOL-Key field description

Field

Description

Descriptor type

Specifies the network type:

·     WPA network.

·     RSN network.

Key information

For more information about this field, see Table 2.

Key length

Length of the key.

Key replay counter

Records the total number of GTK updates to prevent replay attacks.

The AP sets this field to 0 at the beginning of the negotiation and increments the value on each successive EAPOL-Key frame.

The client records this field from the last valid EAPOL-Key frame that it received if this field is greater than the field recorded previously.

EAPOL-Key frame retransmission is required in the following situations:

·     The field received by the client is smaller than or equal to the field recorded by the client.

·     The field received by the AP is not equal to the field recorded on the AP.

If the retransmission attempts exceed the maximum number, the AP disconnects the client.

Key nonce

Random value used to generate the PTK.

EAPOL Key IV

Encrypts the TKIP. This field is valid only when the encryption type is not CCMP.

Key RSC

Records the total number of multicast packets or broadcast packets to prevent replay attacks. The AP increments the value of this field on transmission of each multicast or broadcast packet.

Reserved

Reserved field.

Key MIC

Message integrity check.

Key data length

Length of the key data.

Key data

Data to be transmitted, such as the GTK and pairwise master key identifier (PMKID).

3-bit reserved field. The sender sets this field to 0, and the receiver ignores this field.

WPA key negotiation

WPA uses EAPOL-Key packets in the four-way handshake to negotiate the PTK, and in the two-way handshake to negotiate the GTK.

Figure 5 WPA key negotiation process

WPA key negotiation uses the following process:

1.     The AP sends the client EAPOL-Key message 1 that contains a random value ANonce.

2.     The client performs the following operations:

a.     Uses the random value SNonce, ANonce, and PMK to generate a PTK by using the key derivation function (KDF).

b.     Uses the KCK in the PTK to generate the MIC.

c.     Returns EAPOL-Key message 2 that contains the SNonce and MIC.

3.     The AP performs the following operations:

a.     Uses the SNonce, ANonce, and PMK to generate a PTK by using the KDF.

b.     Uses the KCK in the PTK to generate the MIC.

c.     Compares the received MIC with the local MIC.

d.     Returns EAPOL-Key message 3 that contains the PTK installation request tag and MIC if the two MICs are the same.

4.     The client performs the following operations:

a.     Compares the received MIC with the local MIC.

b.     Installs the PTK and returns EAPOL-Key message 4 that contains the MIC if the two MICs are the same.

5.     The AP performs the following operations:

a.     Compares the received MIC with the local MIC.

b.     Installs the PTK and generates a GTK with the GMK and MAC address of the AP by using the KDF if the two MICs are the same.

c.     Returns EAPOL-Key group message 1 that contains the GTK and MIC.

6.     The client performs the following operations:

a.     Installs the GTK if the two MICs are the same.

b.     Returns EAPOL-Key group message 2 that contains the MIC.

7.     The AP performs the following operations:

a.     Compares the received MIC with the local MIC.

b.     Installs the GTK if the MICs are the same.

RSN key negotiation

RSN uses EAPOL-Key packets in the four-way handshake to negotiate the PTK and the GTK.

Figure 6 RSN key negotiation process

RSN key negotiation uses the following process:

1.     The AP sends the client EAPOL-Key message 1 that contains a random value ANonce.

2.     The client performs the following operations:

a.     Uses the random value SNonce, ANonce, and PMK to generate a PTK by using the KDF.

b.     Uses the KCK in the PTK to generate the MIC.

c.     Returns EAPOL-Key message 2 that contains the SNonce and MIC.

3.     The AP performs the following operations:

a.     Uses the SNonce, ANonce, and PMK to generate a PTK by using the KDF.

b.     Uses the KCK in the PTK to generate the MIC.

c.     Compares the received MIC with the local MIC.

d.     Generates a GTK with the random GMK and MAC address of the AP by using the KDF if the two MICs are the same.

e.     Returns EAPOL-Key message 3 that contains the key installation request tag, MIC, and GTK.

4.     The client performs the following operations:

a.     Compares the received MIC with the local MIC.

b.     Installs the PTK and GTK if the two MICs are the same.

c.     Returns EAPOL-Key message 4 that contains the MIC.

5.     The AP performs the following operations:

a.     Compares the received MIC with the local MIC.

b.     Installs the PTK and GTK if the two MICs are the same.

Key updates

Key updates enhance WLAN security. Key updates include PTK updates and GTK updates.

·     PTK updates—Updates for the unicast keys using the four-way handshake negotiation.

·     GTK updates—Updates for the multicast keys using the two-way handshake negotiation.

Cipher suites

TKIP

Temporal Key Integrity Protocol (TKIP) and WEP both use the RC4 algorithm. You can change the cipher suite from WEP to TKIP by updating the software without changing the hardware. TKIP has the following advantages over WEP:

·     TKIP provides longer initialization vectors (IVs) to enhance encryption security. Compared with WEP encryption, TKIP encryption uses the 128-bit RC4 encryption algorithm, and increases the length of IVs from 24 bits to 48 bits.

·     TKIP allows for dynamic key negotiation to avoid static key configuration. TKIP dynamic keys cannot be easily deciphered.

·     TKIP offers MIC and countermeasures. If a packet has been tampered with, it will fail the MIC. If two packets fail the MIC in a period, the AP automatically takes countermeasures by stopping providing services in a period to prevent attacks.

CCMP

Counter mode with CBC-MAC Protocol (CCMP) is based on the Counter-Mode/CBC-MAC (CCM) of the Advanced Encryption Standard (AES) encryption algorithm.

CCMP contains a dynamic key negotiation and management method. Each client can dynamically negotiate a key suite, which can be updated periodically to further enhance the security of the CCMP cipher suite. During the encryption process, CCMP uses a 48-bit packet number (PN) to make sure each encrypted packet uses a different PN. This improves WLAN security.

Dynamic WEP mechanism

IMPORTANT

IMPORTANT:

The dynamic WEP mechanism uses open system authentication for link layer authentication.

802.11 provides the dynamic WEP mechanism to ensure that each user uses a private WEP key.

·     For unicast communications, the mechanism uses the WEP key negotiated by the client and server during 802.1X authentication.

·     For multicast and broadcast communications, the mechanism uses the configured WEP key. If you do not configure a WEP key, the AP randomly generates a WEP key for broadcast and multicast communications.

After the client passes 802.1X authentication, the AP sends the client an RC4-EAPOL packet that contains the unicast WEP key ID, and the multicast and broadcast WEP key and key ID. The unicast WEP key ID is 4.

802.11w management frame protection

About 802.11w management frame protection

The management frame protection service protects a set of robust management frames, such as de-authentication, disassociation, and some robust action frames.

·     For unicast management frames, it uses the PTK to encrypt the frames and provides secrecy, integrity, and replay protection.

·     For broadcast and multicast management frames, it uses the Broadcast Integrity Protocol (BIP) to provide integrity and replay protection.

The security association (SA) query mechanism is used to enhance security if the AP and client negotiate to use management frame protection. SA queries include active SA queries and passive SA queries.

Active SA query

As shown in Figure 7, active SA query uses the following process:

1.     The client sends an association or reassociation request to the AP.

2.     Upon receiving the request, the AP sends a response to inform the client that the request is denied and the client can associate at a later time. The response contains the association comeback time.

3.     The AP sends an SA query request to verify the status of the client:

¡     If the AP receives an SA query response within the timeout time, it considers the client online.

¡     If the AP does not receive an SA query response within the timeout time, it sends another SA query request. If the AP receives an SA query response within the retransmission time, it considers the client online. The AP does not respond to any association or reassociation requests from the client until the association comeback time times out.

¡     If the AP does not receive an SA query response within the retransmission time, it considers the client offline and allows the client to reassociate.

Figure 7 Active SA query process

Passive SA query

As shown in Figure 8, passive SA query uses the following process:

1.     The client triggers the SA query process upon receiving an unencrypted disassociation or deauthentication frame.

2.     The client sends an SA query request to the AP.

3.     The AP sends an SA query response to the client:

¡     If the client receives the response, the client determines that the AP is online and does not process the disassociation or deauthentication frame.

¡     If the client does not receive a response, the client determines that the AP is offline and disassociates with the AP.

Figure 8 Passive SA query process

Enhanced open system authentication

Enhanced open system authentication uses Opportunistic Wireless Encryption (OWE) to negotiate keys for encrypting data packets of OWE-capable clients, providing open system authentication with enhanced security performance.

Enhanced open system authentication uses the following procedure:

1.     The client sends an authentication request to the AP.

2.     The AP determines that the client can pass wireless link layer authentication and sends an authentication response to the client to notify the client of the authentication success.

3.     The client and the AP perform 4-way handshake to generate a key for encryption.

Enabling PPSK fail-permit

About this task

With PPSK authentication over the cloud platform enabled, clients and devices must connect to the cloud platform for authentication. PPSK fail-permit allows clients to bypass the cloud platform and access the WLAN when the cloud platform is unavailable.

If the cloud platform becomes unavailable, PPSK fail-permit provides the following functions:

·     Allows online clients to stay online until the MAC-password binding entries expire. When the MAC-password binding entries expire, the device logs all online clients.

·     Allows clients whose MAC-password binding entries have not expired to re-access the WLAN.

·     Allows clients that have a correct PPSK password but have never come online to access the WLAN.

Restrictions and guidelines

Make sure the service template has been disabled before you configure this feature.

 

Procedure

1.     Enter system view.

Specifying a recommended service template in transition mode

About this task

During the transition from open WLANs to enhanced open WLANs, WLANs of both types might exist to accommodate OWE-incapable and OWE-capable clients. In this case, if an OWE-capable client attempts to access an open WLAN or if an OWE-incapable client attempts to access an enhanced open WLAN, the corresponding AP will reject the access request.

This feature allows clients to fast access an appropriate WLAN that matches its capability.

Restrictions and guidelines

Configure this feature in both an open service template and an enhanced open service template, and specify them as the recommended template of each other.

Bind a service template and its recommended service template to the same radio.

Enable SSID hidden for the enhanced open service template.

Procedure

1.     Enter system view.

system-view

2.     Enter service template view.
