2 Introduction
The Huawei SWITCH are multi-chip standalone cryptographic modules enclosed in hard,
commercial grade metal cases. The cryptographic boundary for these modules is the
enclosure. The primary purpose of these modules is to provide secure communication for data
transmitted between different networks. The modules provide network interfaces for data
input and output. The appliance encryption technology uses FIPS approved algorithms.
FIPS approved algorithms are approved by the U.S. government for protecting Unclassified
data.
The module is designated as a limited operational environment under the FIPS 140-2
definitions. The module includes a firmware load service to support necessary updates. New
firmware versions within the scope of this validation must be validated through the FIPS 140-
2 CMVP. Any other firmware loaded into this module is out of the scope of this validation
and require a separate FIPS 140-2 validation.

4 Cryptographic Functionality
The cryptographic protocols and primitives implemented and used by the modules are listed
in this section. Table 4-1 and Table 4-2 list the TLS ciphersuites available in the Approved and
non-Approved modes, respectively. Table 4-3 lists the SSH security methods; unlike TLS
ciphersuites, SSH methods are independently selectable and may be used in any combination.
The module supports both an Approved and non-Approved mode of operation. By default,
the module comes configured in the non-Approved mode. In the Approved mode, only the
services listed in Tables 5-2 and 5-3 are available; further, the SSHv2 service is constrained to
use only the Approved SSH options listed in Table 4-3. In the non-approved mode, all
services in Tables 5-2, 5-3 and 5-4 are available for use, and all SSH options from Tables 4-3
are available.
The module supports https using TLS ciphersuites below in the Approved mode, supporting
TLS to redirect all http connections to https (with TLS) and FTP to FTPS (with TLS) and to
assure that a user cannot accidently downgrade browser security.

5 Roles, Authentication and Services
5.1 Assumption of Roles
The module does not support a maintenance role or bypass capability. The module supports
concurrent use by End Users and Administrators. The cryptographic module enforces the
separation of roles by the partitioning of major subsystems (such as end user traffic vs. shell
or administrative functions), and by partitioning of the administrative interfaces (e.g. by
organization of the web GUI pages). Authentication status does not persist across module
power cycles. To change roles, an operator must first log out, then log in using another role.
Table 5-1 lists the available roles; the options for authentication type and data are common
across roles.

5.2 Authentication Methods
The Local password verification method requires an 8 character minimum password using
characters from at least two categories of printable character sets (upper case, lower case,
special character, and numbers).
Since there are 28 possible special characters, 10 number characters and 26 upper or
lower case characters, the weakest password that meets the policy but whose
components are still chosen randomly would be 7 digits and one upper or lower case
character. This results in an upper bound probability of (10^7) x 26. So, the probability
of guessing the password with a single attempt is 1/(2.6x10^8) which is less than one in
1,000,000.
For SSH connections, after n consecutive unsuccessful authentication attempts, the module
will lockout additional authentication requests for a minimum of 5 minutes. The default value
for n is 3, but per the security rules must be less than 2600.
The probability of false authentication in a one minute period is 2599/(2.6x10^8) =
1/100038.
Huawei S7700 Series Switches FIPS 140-2 Security Policy
Issue 1.1 (2017-07-26) Copyright © Huawei Technologies Co., Ltd. 21
For console access, after 1 unsuccessful attempt, the module requires a waiting period of 5
seconds before accepting another authentication attempt. Thus, only 12 authentication
attempts are possible over the console in a one minute period.
The probability of a false authentication in a one minute period is 12/(2.6x10^8), which
is less than 1 in 100,000.
The digital signature verification method, used for SSH client-side authentication, is based on
the verification of a 2048-bit RSA or DSA digital signature, which has a minimum equivalent
computational resistance to attack of 2112
.
The probability of a successful random attempt is 1/ (2112
), which is less than
1/1,000,000.
Processing speed limits the number of failed authentication attempts in a one-minute period to
120 attempts.
The probability of a success with multiple consecutive attempts in a one-minute period
is 120/(2112
), which is less than 1/100,000.

The Module Reset service instantiates the DRBG, with 1024 bytes of entropy input (DRBG-
EI) produced by the Allowed NDRNG. The generation of DRBG-State uses the [SP 800-90A]
Hash_df with 660 bits of entropy input. Internally generated symmetric keys are the result of
unmodified output from the DRBG. The zeroization of session keys by this service covers the
case of module shutdown or power-cycle while a secure channels session (SSH, TLS) is
active.
The Show Status service does not access CSPs or public keys.

6 Self-tests
Each time the module is powered up it tests that the cryptographic algorithms still operate
correctly and that sensitive data have not been damaged. Power up self–tests are available on
demand by power cycling the module.
On power up or reset, the module performs the self tests described in below. All KATs must
be completed successfully prior to any other use of cryptography by the module. Once called,
the initialization function does not allow any user intervention.
All data output via the data output interface is inhibited when an error state exists and during
self-tests. Upon successful completion of the self-tests the modules SYS LED will go from
Red to Green. If a failure of a self-test occurs, the module enters an error state, outputs the
following error message on the console and forces the module to reboot: “Self-Test Fail…”

10 Security Rules and Guidance
The module design corresponds to the module security rules. The module implements and
enforces the following security rules:
1. An unauthenticated operator does not have access to any CSPs or cryptographic services.
2. The module inhibits data output during power up self-tests and error states.
3. Status information does not contain CSPs or sensitive data that if misused could lead to a
compromise of the module.
4. Zeroization overwrites all CSPs.
5. The module does not share CSPs between the Approved mode of operation and the non-
Approved mode of operation.
The following security rules must be adhered to for operation in the FIPS 140-2 Approved
mode:
6. Upon first time initialization, the Root Administrator (CO) shall authenticate to the
module using the default username and password:
Username: admin
Password: Admin@huawei
7. Set the workmode to FIPS:
The following CLI command initiates the steps for placing the controller in FIPS
approved mode of operations, and enabling all necessary algorithm restrictions. All
necessary self-tests are carried out in both FIPS and non-FIPS modes.
[quidway]set work-mode fips
Warning: The work mode of device will change and system will restart. Continue?
[Y/N]: y
After completing the steps, saving the configuration and rebooting, the Controller stays in
FIPS mode unless the FIPS mode is explicitly disabled. The non-approved cryptographic
algorithms do not get used in FIPS mode unless they are explicitly configured.
To view the current mode of operation, the following CLI command needs to be used:
[quidway]display work-mode
Work mode : FIPS
Upon the reboot the CO shall update from the default username and password. The
minimum password strength is enforced by the module per Section 3.2. The CO can then
create Administrator and End User accounts and proceed with module configuration per
the vendor provided user manual (available here: http://
http://support.huawei.com/enterprise/en/switch/s7700-pid-6805481).
A crypto officer can use the following CLI command to set user passwords:
[quidway-aaa]local-user user-name password irreversible-cipher password
[quidway-aaa]local-user user-name service-type https/ssh
[quidway-aaa]local-user user-name privilege level 15
[quidway-aaa]local-aaa-user password policy administrator (optional)
Note that this and all subsequent configuration steps may also be performed through
HTTPS. However, only the CLI commands are included in this document.
8. Configure SSH using the following:
Huawei S7700 Series Switches FIPS 140-2 Security Policy
Issue 1.1 (2017-07-26) Copyright © Huawei Technologies Co., Ltd. 35
[quidway]ssh user user-name
[quidway] ssh user user-name authentication-type {password | rsa | password-rsa | all |
dsa | password-dsa}
[quidway] ssh user username service-type stelnet / sftp
[quidway] rsa local-key-pair create, or dsa local-key-pair create.
[quidway] ssh server key-exchange dh_group_exchange_sha1
9. Configure an HTTPS Certificate
The following commands configure the web server to use the manufacturer-installed
switch device certificate for the HTTPS server. It must be executed after enabling FIPS
mode of operation:
[quidway] ssl policy policy-name
Load a PEM certificate or certificate chain. Run either of the following commands based
on whether a user obtains a digital certificate or certificate chain from the CA.
[quidway] certificate load pem-cert cert-filename key-pair { dsa | rsa } key-file key-
filename auth-code cipher auth-code
A PEM digital certificate is loaded and the private key file is specified.
Or:
[quidway] certificate load pem-chain cert-filename key-pair { dsa | rsa } key-file key-
filename auth-code cipher auth-code
A PEM certificate chain is loaded and the private key file is specified.
[quidway] certificate load asn1-cert cert-filename key-pair { dsa | rsa } key-file key-
filename
An ASN1 digital certificate is loaded and the private key file is specified.
[quidway] certificate load pfx-cert cert-filename key-pair { dsa | rsa } { mac cipher
mac-code | key-file key-filename } auth-code cipher auth-code
A PFX digital certificate is loaded and the private key file is specified.
[quidway] http secure-server ssl-policy policy-name
In non-FIPS mode, a self-signed certificate may be used for the HTTPS server.
10. The CO must not configure the failed authentication limit setting for more than 2599.
11. Save and Reboot
After executing the above commands, you must save the configuration and reboot the
system:
<quidway> save
<quidway> reboot
An operator of the module can determine if the module is running the in Approved mode
of operation by adhering to the above rules.
