17 3.3 Modes of Operat ion The module has the following FIPS ap proved modes of operations: • Remote AP ( RAP) FIP S mode – When the module is co nfigured as a Remote AP, it is intended to be deplo yed in a remote location (relative to the Mobilit y Controller).
18 5. Enable FIP S mode o n the AP. This accomplished b y going to the Configuration > Wireless > AP Configuration > AP Group p age. There, you click the E dit button for the appropriate AP group, and then select AP > AP Syste m Profile. Then, check the “Fips Enable” bo x, check “ Apply”, and save the configuration.
19 6. If the staging controller does not pr ovide PoE, either ens ure the presence of a P oE injector for the LAN co nnection between the module and the controller , o r ens ure the prese nc e o f a D C po wer supply appropriate to the particular model of the module 7.
20 represents the o nly exception. That is, nothing o ther than a P oE injector should be present between the module and the sta ging controller. 8. Once the module is connected to the controller by the Ethernet cable, navigate to the Configuration > Wireless > AP Installa tion page, where you sho uld see an entry for the AP.
21 select AP > AP Syste m Profile. Then, check the “Fips Enable” bo x, check “ Apply”, and save the configuration. 6. If the staging controller does not pr ovide PoE, either ens ure the pre.
22 Linux impleme ntation is not provided d irectly. O nly Aruba-pro vided Crypto O fficer interfaces ar e used. There is no user interface p rovided. 3.5 Logical Interfaces The physical interfaces are divided into logical interface s defi ned b y FIP S 14 0 -2 as described in the following table.
23 4 Roles, Authentication and Ser vices 4.1 Roles The module supports the roles of Cr ypto Officer, User, and Wireless Client; no add itional roles (e.g., Maintenance) are supported . Administrative oper ations car ried out b y the Aruba Mobility Controller map to the Crypto O fficer role.
24 4.1.2 User Authentication Authentication for the User role depends on the module co nfiguration. When the module is configured as a Mesh AP , the User role is authenticated via the WP A2 preshared key.
25 Authentication Mechanis m Mechanis m Strengt h Wireless Client WPA2-PSK (Wireless Client Role) For WPA2 -PSK there are at least 95^1 6 (=4.4 x 10^31 ) possible combinations. In order to test a guessed key, the attac ker must complete the 4-way handshake with the AP.
26 4.2 Services The module provides vario us services depending o n role. These are described below. 4.2.1 Crypto Officer Services The CO role in each of FIP S modes defi ned in section 3.
27 Service Description CSPs Accessed (see sectio n 6 below for complete descriptio n of CSPs) Creation/use of secure management session bet ween module and CO The module supports use of IPSec for securing the management channel.
28 Service Description CSPs Accessed (see sectio n 6 below for complete d escription of CSPs) 802.11i AES-C CM key 802.11i GMK 802.11i GTK Use of WPA preshared ke y for establishment of IEEE 802.11i keys When the module is i n mesh configuration, the inter -module mesh links are secured with 802.
29 4.2.4 Unauthenticated Serv ices The module pr ovides the foll owing unauthenticated services, which are available regardless o f ro le. No CSPs are accessed b y these services. System status – SYSLOG and module LEDs 802.11 a/b/g/n FTP TFTP NTP GRE tunneling of 802 .
30 5 Cryp tographic A l gorithms FIPS-approved cryptographic algorithms have bee n implemented in hard w are and firmware. The firmware suppo rts the following cryptographic imple mentations. ArubaOS OpenSSL AP Module implements the follo wing FIPS -appr oved algorithms: o AES (Cert.
31 6 Critical Securit y Parameters The following Critical Sec urity Parameters (CSPs) are used by the module: CSP CSP TYPE GENERATION STORAGE And ZEROIZATI ON USE Key E ncryption Key (KEK) Triple-DES 168 -bits key Hard-coded Stored in flash, zeroized b y the ‘ ap wipe out flash’ command.
32 CSP CSP TYPE GENERATION STORAGE And ZEROIZATI ON USE IKEv1/IKEv2 Diffie - Hellman Private key 1024 -bit Diffie- Hellman private key Generated internall y during IKEv1/IKEv2 negotiation Stored in pl.

34 CSP CSP TYPE GENERATION STORAGE And ZEROIZATI ON USE 802.11i Gro up Master Key (GMK) 256 -bit secret used to derive GTK Generated from appro ved RNG Stored in plaintext in volatile memory; zeroized o n reboot Used to derive Group Transient Key (GTK) 802.
35 7 Self T ests The module performs the following Self Tests after being configured into either Remote AP mode or Remote Mesh P ortal mode. The module perfor ms both po wer-up and conditio nal self -tests. In the eve nt any se lf -test fails, t he module enters an error state, logs the error, and reb oots automatically.
