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 approved as well as non-approved RNGs.

Bypass test



RSA Pairwise Consistency test



ECDSA Pairwise Consistency test



Firmware Load Test



Self-test results are logged in a log file. Upon successful completion of the power-up self tests, the module

logs a KATS: passed message into a log file. Confirm the file update by checking the associated time of the

file.

In the event of a hardware KATs failure, the log file records one of the following messages depending on the

algorith being tested:



AES256 HMAC-SHA1 hash failed



AES256 Encrypt failed



AES256 Decrypt Failed



3DES HMAC-SHA1 hash failed



3DES Encrypt failed



3DES Decrypt Failed



DES HMAC-SHA1 hash failed



DES Encrypt failed



DES Decrypt Failed



HW KAT test failed for AESCCM CTR. Rebooting



AESCCM Encrypt Failed

This text is followed by this message:

The POST Test failed!!!!

Alternating Bypass State

The controller implements an alternating bypass state when:

a port is configured in trusted mode to provide unauthenticated services



a configuration provides wireless access without encryption



The alternating bypass status can be identified by retrieving the port configuration or the wireless network

configuration.

Mitigation of Other Attacks

ArubaOS includes two modules that provide protection from attacks. These are:

XSec



Wireless Intrusion Protection



XSec

xSec is a highly secure data link layer (Layer 2) protocol that provides a unified framework for securing all

wired and wireless connections using strong encryption and authentication. xSec provides greater security

than Layer 3 encryption technologies through the use of FIPS-validated encryption algorithms (AES-CBC-

256 with HMAC-SHA1) to secure Layer 2 traffic, as well as the encryption of Layer 2 header information

including MAC addresses. xSec was jointly developed by Aruba Networks and Funk Software.
