3.2 Physical Security
The Aruba Wireless AP is a scalable, multi-processor standalone network device and is enclosed in a robust
plastic housing. The AP enclosure is resistant to probing (please note that this feature has not been tested as
part of the FIPS 140-2 validation) and is opaque within the visible spectrum. The enclosure of the AP has
been designed to satisfy FIPS 140-2 Level 2 physical security requirements.
3.2.1 Applying TELs
The Crypto Officer is responsible for securing and having control at all times of any unused tamper evident
labels. The Crypto Officer should employ TELs as follows:
 Before applying a TEL, make sure the target surfaces are clean and dry.
 Do not cut, trim, punch, or otherwise alter the TEL.
 Apply the wholly intact TEL firmly and completely to the target surfaces.
 Ensure that TEL placement is not defeated by simultaneous removal of multiple modules.
 Allow 24 hours for the TEL adhesive seal to completely cure.
 Record the position and serial number of each applied TEL in a security log.
For physical security, the AP requires Tamper-Evident Labels (TELs) to allow detection of the opening of
the device, and to block the serial console port (on the bottom of the device). The tamper-evident labels
shall be installed for the module to operate in a FIPS approved mode of operation. To protect the device
from tampering, TELs should be applied by the Crypto Officer as pictured below:

3.3 Modes of Operation
The module has the following FIPS approved modes of operations:
• Remote AP (RAP) FIPS mode – When the module is configured as a Remote AP, it is intended to
be deployed in a remote location (relative to the Mobility Controller). The module provides
cryptographic processing in the form of IPSec for all traffic to and from the Mobility Controller.
• Control Plane Security (CPSec) protected AP FIPS mode – When the module is configured as a
Control Plane Security protected AP it is intended to be deployed in a local/private location (LAN,
WAN, MPLS) relative to the Mobility Controller). The module provides cryptographic processing
in the form of IPSec for all Control traffic to and from the Mobility Controller.
• Remote Mesh Portal FIPS mode – When the module is configured in Mesh Portal mode, it is
intended to be connected over a physical wire to the mobility controller. These modules serve as
the connection point between the Mesh Point and the Mobility Controller. Mesh Portals
communicate with the Mobility Controller through IPSec and with Mesh Points via 802.11i
session. The Crypto Officer role is the Mobility Controller that authenticates via IKEv1/IKEv2
pre-shared key or RSA certificate authentication method, and Users are the "n" Mesh Points that
authenticate via 802.11i preshared key.
• Mesh Point FIPS MODE – an AP that establishes all wireless path to the Remote Mesh portal in
FIPS mode over 802.11 and an IPSec tunnel via the Remote Mesh Portal to the controller.
This section explains how to place the module in FIPS mode in either Remote AP FIPS mode, Control
Plane Security AP FIPS Mode, Remote Mesh Portal FIPS mode or Mesh Point FIPS Mode. How to verify
that it is in FIPS mode. An important point in the Aruba APs is that to change configurations from any one
mode to any other mode requires the module to be re-provisioned and rebooted before any new configured
mode can be enabled.
The access point is managed by an Aruba Mobility Controller in FIPS mode, and access to the Mobility
Controller’s administrative interface via a non-networked general purpose computer is required to assist in
placing the module in FIPS mode. The controller used to provision the AP is referred to below as the
“staging controller”. The staging controller must be provisioned with the appropriate firmware image for
the module, which has been tested to FIPS 140-2, prior to initiating AP provisioning.
After setting up the Access Point by following the basic installation instructions in the module User
Manual, the Crypto Officer performs the following steps:
3.3.1 Configuring Remote AP FIPS Mode
1. Apply TELs according to the directions in section 3.2
2. Log into the administrative console of the staging controller
3. Deploying the AP in Remote FIPS mode configure the controller for supporting Remote APs, For
detailed instructions and steps, see Section “Configuring the Secure Remote Access Point Service”
in Chapter “Remote Access Points” of the Aruba OS User Manual.
4. Enable FIPS mode on the controller. This is accomplished by going to the Configuration > Network
> Controller > System Settings page (this is the default page when you click the Configuration tab), and
clicking the FIPS Mode for Mobility Controller Enable checkbox.
5. Enable FIPS mode on the AP. This accomplished by going to the Configuration > Wireless > AP
Configuration > AP Group page. There, you click the Edit button for the appropriate AP group, and then
select AP > AP System Profile. Then, check the “Fips Enable” box, check “Apply”, and save the
configuration.

6. If the staging controller does not provide PoE, either ensure the presence of a PoE injector for the
LAN connection between the module and the controller, or ensure the presence of a DC power
supply appropriate to the particular model of the module.
7. Connect the module via an Ethernet cable to the staging controller; note that this should be a direct
connection, with no intervening network or devices; if PoE is being supplied by an injector, this
represents the only exception. That is, nothing other than a PoE injector should be present between
the module and the staging controller.
8. Once the module is connected to the controller by the Ethernet cable, navigate to the
Configuration > Wireless > AP Installation page, where you should see an entry for the AP. Select
that AP, click the “Provision” button, which will open the provisioning window. Now provision
the AP as Remote AP by filling in the form appropriately. Detailed steps are listed in Section
“Provisioning an Individual AP” of Chapter “The Basic User-Centric Networks” of the Aruba OS
User Guide. Click “Apply and Reboot” to complete the provisioning process.
a. During the provisioning process as Remote AP if Pre-shared key is selected to be the
Remote IP Authentication Method, the IKE pre-shared key (which is at least 8 characters
in length) is input to the module during provisioning. Generation of this key is outside the
scope of this policy. In the initial provisioning of an AP, this key will be entered in
plaintext; subsequently, during provisioning, it will be entered encrypted over the secure
IPSec session. If certificate based authentication is chosen, AP’s RSA key pair is used to
authenticate AP to controller during IPSec. AP’s RSA private key is contained in the
AP’s non volatile memory and is generated at manufacturing time in factory.
9. Via the logging facility of the staging controller, ensure that the module (the AP) is successfully
provisioned with firmware and configuration
10. Terminate the administrative session
11. Disconnect the module from the staging controller, and install it on the deployment network; when
power is applied, the module will attempt to discover and connect to an Aruba Mobility Controller
on the network.
3.3.2 Configuring Control Plane Security (CPSec) protected AP FIPS mode
1. Apply TELs according to the directions in section 3.2
2. Log into the administrative console of the staging controller
3. Deploying the AP in CPSec AP mode, configure the staging controller with CPSec under
Configuration > Controller > Control Plane Security tab. AP will authenticate to the controller
using certificate based authentication to establish IPSec. AP is configured with RSA key pair at
manufacturing. AP’s certificate is signed by Aruba Certification Authority (trusted by all Aruba
controllers) and the AP’s RSA private key is stored in non-volatile memory. Refer to “Configuring
Control Plane Security” Section in ArubaOS User Manual for details on the steps.
4. Enable FIPS mode on the controller. This is accomplished by going to the Configuration > Network
> Controller > System Settings page (this is the default page when you click the Configuration tab), and
clicking the FIPS Mode for Mobility Controller Enable checkbox.
5. Enable FIPS mode on the AP. This accomplished by going to the
Configuration > Wireless > AP Configuration > AP Group page. There, you click the Edit button for the

“Provisioning an Individual AP” of Chapter “The Basic User-Centric Networks” of the Aruba OS
User Guide. Click “Apply and Reboot” to complete the provisioning process.
a. For CPSec AP mode, the AP always uses certificate based authentication to establish
IPSec connection with controller. AP uses the RSA key pair assigned to it at
manufacturing to authenticate itself to controller during IPSec. Refer to “Configuring
Control Plane Security” Section in Aruba OS User Manual for details on the steps to
provision an AP with CPSec enabled on controller.
9. Via the logging facility of the staging controller, ensure that the module (the AP) is successfully

3.5 Logical Interfaces
The physical interfaces are divided into logical interfaces defined by FIPS 140-2 as described in the
following table.
Table 6 - FIPS 140-2 Logical Interfaces
FIPS 140-2 Logical Interface Module Physical Interface
Data Input Interface 10/100/1000 Ethernet Ports

Power Interface Power Supply
Data input and output, control input, status output, and power interfaces are defined as follows:
 Data input and output are the packets that use the networking functionality of the module.
 Control input consists of manual control inputs for power and reset through the power interfaces.
It also consists of all of the data that is entered into the access point while using the management
interfaces.
 Status output consists of the status indicators displayed through the LEDs, the status data that is
output from the module while using the management interfaces, and the log file.
o LEDs indicate the physical state of the module, such as power-up (or rebooting),
utilization level, and activation state. The log file records the results of self-tests,
configuration errors, and monitoring data.
 A power supply may be used to connect the electric power cable. Operating power may also be
provided via Power Over Ethernet (POE) device when connected. The power is provided through
the connected Ethernet cable.
 Console port is disabled when operating in each of FIPS modes.
The module distinguishes between different forms of data, control , and status traffic over the network ports
by analyzing the packet headers and contents.

4 Roles, Authentication and Services
4.1 Roles
The module supports the roles of Crypto Officer, User, and Wireless Client; no additional roles (e.g.,
Maintenance) are supported. Administrative operations carried out by the Aruba Mobility Controller map
to the Crypto Officer role. The Crypto Officer has the ability to configure, manage, and monitor the
module, including the configuration, loading, and zeroization of CSPs.
Defining characteristics of the roles depend on whether the module is configured as a Remote AP mode or
as a Remote Mesh Portal mode.
 Remote AP:
o Crypto Officer Role: the Crypto Officer is the Aruba Mobility Controller that has the
ability to configure, manage, and monitor the module, including the configuration,
loading, and zeroization of CSPs.
o User role: in the standard configuration, the User operator shares the same services and
authentication techniques as the Mobility Controller in the Crypto Officer role.
o Wireless Client role: in Remote AP configuration, a wireless client can create a
connection to the module using WPA2 and access wireless network access/bridging
services. In advanced Remote AP configuration, when Remote AP cannot communicate
with the controller, the wireless client role authenticates to the module via WPA2-PSK
only.
 CPSec AP:
o Crypto Officer Role: the Crypto Officer is the Aruba Mobility Controller that has the
ability to configure, manage, and monitor the module, including the configuration,
loading, and zeroization of CSPs.
o User role: in the standard configuration, the User operator shares the same services and
authentication techniques as the Mobility Controller in the Crypto Officer
o Wireless Client role: in CPSec AP configuration, a wireless client can create a connection
to the module using WPA2 and access wireless network access services.
 Mesh AP (Mesh Point or Remote Mesh Portal configuration):
o Crypto Officer role: the Crypto Officer role is the Aruba Mobility Controller that has the
ability to configure, manage, and monitor the module, including the configuration,
loading, and zeroization of CSPs.
o User role: the second (or third, or nth) AP in a given mesh cluster
o Wireless Client role: in Mesh AP configuration, a wireless client can create a connection
to the module using WPA2 and access wireless network access services.
4.1.1 Crypto Officer Authentication
In each of FIPS approved modes, the Aruba Mobility Controller implements the Crypto Officer role.
Connections between the module and the mobility controller are protected using IPSec. Crypto Officer
authentication is accomplished via either proof of possession of the IKEv1/IKEv2 pre-shared key or RSA
certificate, which occurs during the IKEv1/IKEv2 key exchange.
Page: 32
33
4.1.2 User Authentication
Authentication for the User role depends on the module configuration. When the module is configured as a
Remote Mesh Portal FIPS mode and Remote Mesh Point FIPS mode, the User role is authenticated via the
WPA2 pre-shared key. When the module is configured as a Remote AP FIPS mode and CPSec protected
AP FIPS mode, the User role is authenticated via the same IKEv1/IKEv2 pre-shared key/RSA certificate
that is used by the Crypto Officer
4.1.3 Wireless Client Authentication
The wireless client role defined in each of FIPS approved modes authenticates to the module via WPA2.
Please notice that WEP and/or Open System configurations are not permitted in FIPS mode. In advanced
Remote AP configuration, when Remote AP cannot communicate with the controller, the wireless client
role authenticates to the module via WPA2-PSK only.
4.1.4 Strength of Authentication Mechanisms
The following table describes the relative strength of each supported authentication mechanism.
Authentication
Mechanism
Mechanism Strength
IKEv1/IKEv2
shared secret (CO
role)
For IKEv1/IKEv2, there are a 95^8 (=6.63 x 10^15) possible pre-shared keys.
In order to test the guessed key, the attacker must complete an IKEv1/IKEv2
aggressive mode exchange with the module. IKEv1/IKEv2 aggressive mode
consists of a 3 packet exchange, but for simplicity, let’s ignore the final
packet sent from the AP to the attacker.
An IKEv1/IKEv2 aggressive mode initiator packet with a single transform,
using Diffie-Hellman group 2, and having an eight character group name has
an IKEv1/IKEv2 packet size of 256 bytes. Adding the eight byte UDP header
and 20 byte IP header gives a total size of 284 bytes (2272 bits).
The response packet is very similar in size, except that it also contains the
HASH_R payload (an additional 16 bytes), so the total size of the second
packet is 300 bytes (2400 bits).
Assuming a link speed of 1Gbits/sec (this is the maximum rate supported by
the module), this gives a maximum idealized guessing rate of 60,000,000,000
/ 4,672 = 12,842,466 guesses per minute. This means the odds of guessing a
correct key in one minute is less than 12,842,466/(6.63x10^15) = 1.94 x 10^-
9, which is much less than 1 in 10^5.
Page: 33
34
Authentication
Mechanism
Mechanism Strength
Wireless Client
WPA2-PSK
(Wireless Client
role)
For WPA2-PSK there are at least 95^16 (=4.4 x 10^31) possible
combinations. In order to test a guessed key, the attacker must complete the
4-way handshake with the AP. Prior to completing the 4-way handshake, the
attacker must complete the 802.11 association process. That process involves
the following packet exchange:
 Attacker sends Authentication request (at least 34 bytes)
 AP sends Authentication response (at least 34 bytes)
 Attacker sends Associate Request (at least 36 bytes)
 AP sends Associate Response (at least 36 bytes)
Total bytes sent: at least 140. Note that since we do not include the actual 4-
way handshake, this is less than half the bytes that would actually be sent, so
the numbers we derive will absolutely bound the answer.
The theoretical bandwidth limit for IEEE 802.11n is 300Mbit, which is
37,500,000 bytes/sec. In the real world, actual throughput is significantly less
than this, but we will use this idealized number to ensure that our estimate is
very conservative.
This means that the maximum number of associations (assume no delays, no
inter-frame gaps) that could be completed is less than 37,500,000/214 =
267,857 per second, or 16,071,429 associations per minute. This means that
an attacker could certainly not try more than this many keys per second (it
would actually be MUCH less, due to the added overhead of the 4-way
handshake in each case), and the probability of a successful attack in any 60
second interval MUST be less than 16,071,429/(4.4 x 10^31), or roughly 1 in
10^25, which is much less than 1 in 10^5.
Mesh AP WPA2
PSK (User role)
Same as Wireless Client WPA2-PSK above
RSA Certificate
based authentication
(CO role)
The module supports RSA 1024 bit keys and 2048-bit RSA keys. RSA 1024
bit keys correspond to 80 bits of security. The probability of a successful
random attempt is 1/(2^80), which is less than 1/1,000,000. The probability of
a success with multiple consecutive attempts in a one-minute period is less
than 1/100,000.

7 Self Tests
The module performs the following Self Tests after being configured into either Remote AP mode or
Remote Mesh Portal mode. The module performs both power-up and conditional self-tests. In the event any
self-test fails, the module enters an error state, logs the error, and reboots automatically.
The module performs the following power-up self-tests:
 Aruba Hardware known Answer tests:
o AES KAT
o HMAC-SHA1 KAT
o Triple-DES KAT
 ArubaOS OpenSSL AP Module
o AES KAT
o HMAC (HMAC-SHA1, HMAC-SHA256 and HMAC SHA384) KAT
o RNG KAT
o RSA KAT
o SHS (SHA1, SHA256 and SHA384) KAT
o Triple-DES KAT
 ArubaOS Cryptographic Module
o AES KAT
o HMAC (HMAC-SHA1, HMAC-SHA256, HMAC SHA384, and HMAC512) KAT
o FIPS 186-2 RNG KAT
o RSA (sign/verify)
o SHS (SHA1, SHA256, SHA384, and SHA512) KAT
o Triple-DES KAT
 ArubaOS Uboot Bootloader Module
o Firmware Integrity Test: RSA 2048-bit Signature Validation
 Aruba Atheros hardware CCM
o AES-CCM KAT
The following Conditional Self-tests are performed in the module:
 Continuous Random Number Generator Test–This test is run upon generation of random data by
the module’s random number generators to detect failure to a constant value. The module stores
the first random number for subsequent comparison, and the module compares the value of the
new random number with the random number generated in the previous round and enters an error
state if the comparison is successful. The test is performed for the approved as well as non-
approved RNGs.
 RSA pairwise Consistency Test
 Firmware load test
These self-tests are run for the Atheros hardware cryptographic implementation as well as for the Aruba
OpenSSL and ArubaOS cryptographic module implementations.
Page: 44
45
Self-test results are written to the serial console.
In the event of a KATs failure, the AP logs different messages, depending on the error.
For an ArubaOS OpenSSL AP module and ArubaOS cryptographic module KAT failure:
AP rebooted [DATE][TIME] : Restarting System, SW FIPS KAT failed
For an AES Atheros hardware POST failure:
Starting HW SHA1 KAT ...Completed HW SHA1 AT
Starting HW HMAC-SHA1 KAT ...Completed HW HMAC-SHA1 KAT
Starting HW DES KAT ...Completed HW DES KAT
Starting HW AES KAT ...Restarting system.
