Security Policy, page by page

Zebra Technologies Corporation Non-Proprietary FIPS 140-3 Security Policy For Zebra 8887 Cryptographic Module Firmware-Hybrid Module HW ID:9134 Firmware Versions: FIPS Driver Firmware Version 2.1 and NXP Firmware Version 15.68.19.p59 Documentation Version 1.1 Last Update: June 18, 2024 Zebra Technologies Public Material – May be reproduced only in its original entirety (without revision).

This document defines the Security Policy for Zebra 8887 Cryptographic Module from Zebra Technologies Corporation; hereinafter referred to as the Module. The module resides in the wireless LAN (WLAN) data plane of several Zebra Technologies devices. The Module meets FIPS 140-3 overall Level 1 requirements. The module is intended for use by US Federal agencies and other markets that require FIPS 140-3 validated Zebra devices. The below table indicates the individual cause levels and over levels. Table 1 - Security Levels The module is a multi-chip standalone Firmware-hybrid module. The module’s cryptographic boundary includes the NXP 88W8887 CPU and the driver firmware providing the interface to the 88W8887 CPU. The module’s cryptographic boundary includes the following components: Zebra Technologies Public Material – May be reproduced only in its original entirety (without revision).

The module has been tested on the following platforms: Table 3

• Tested Operational Environments The CMVP makes no statement as to the correct operation of the module or the security strengths of the generated keys when ported to an operational environment which is not listed on the validation certificate. Modes of Operation By design, the module can only support approved mode of operation and does not implement any NonApproved Security Functions. The module does not claim the implementation of a degraded mode of operation. The table below lists all approved security functions of the module, including specific key size(s) -in bits unless otherwise noted- employed for approved services, and implemented modes of operation. There are some algorithm modes that were tested but not implemented by the module. Only the algorithms, modes, and key sizes that are implemented by the module are shown in this table. Table 4
• Approved Algorithms As the module can only be operated in the Approved mode of operation, and any algorithms not listed in table 4 above will be rejected by the module while in the approved mode, the tables defined in SP800140B for the following categories are missing from this document.
• Non-Approved Algorithms Allowed in Approved Mode of Operation
• Non-Approved Algorithms Allowed in Approved Mode of Operation with No Security Claimed
• Non-Approved Algorithms Not Allowed in Approved Mode of Operation Zebra Technologies Public Material
• May be reproduced only in its original entirety (without revision).

Cryptographic Boundary The module is defined as a multi-chip standalone Firmware-hybrid module (thin red line area), with the boundary of the Tested Operational Environment’s Physical Perimeter (TOEPP) being defined as the physical perimeter of the tested platform enclosure around which everything runs.

• May be reproduced only in its original entirety (without revision).

The module’s physical perimeter encompasses the case of the tested platform mentioned in Table

2. The module provides its logical interfaces via Application Programming Interface (API) calls. The logical interfaces provided by the module are mapped onto the FIPS 140-3 interfaces (data input, data output, Table 5 – Ports and Interfaces
3. Roles, Services, and Authentication The module supports Crypto Officer (CO) role. The cryptographic module does not provide any authentication methods. The module does not allow concurrent operators. The Crypto Officer is implicitly assumed based on the service requested. The module provides the following services to the Zebra Technologies Public Material – May be reproduced only in its original entirety (without revision).

The table below lists all approved services that can be used in the approved mode of operation. The abbreviations of the access rights to keys and SSPs have the following interpretation: G = Generate: The module generates or derives the SSP. R = Read: The SSP is read from the module. W = Write: The SSP is updated, imported, or written to the module. E = Execute: The module uses the SSP in performing a cryptographic operation. N/A = The service does not access any SSP during its operation. Table 7

• Approved Services Integrity Techniques The module is provided in the form of binary executable code. To ensure the firmware security, the module is protected by HMAC-SHA-1 (HMAC Cert. #A2718) algorithm. The firmware integrity test key (non-SSP) was preloaded to the module’s binary at the factory and used for firmware integrity test only at Zebra Technologies Public Material

the pre-operational self-test. At module initialization, the HMAC value is recalculated and compared to the hardcoded build-time generated MAC value. If at load time the signature does not match, the crypto module library exits with error. If at any point the integrity checks or known answer test fails, the module will go into an error state and will not be useable until the module is power cycled, and the integrity checks and known answer tests are run again. Integrity Test On-Demand While the integrity test is performed as part of the Pre-Operational Self Tests, the operator can also run the on-demand tests at any time using the API or by power cycling the device.

6. Operational Environment The module operates QNX 7.0.4, which is a non-modifiable operational environment installed on a generic operating platform (e.g., printer). The firmware driver component of the module is loaded onto the embedded OS prior to deployment to the end user. The QNX 7.0 embedded operating system runs in single operator mode only. The module has been tested on QNX 7.0 running on a Zebra ZQ521 printer with i.MX6ULL CPU.
7. Physical Security The module’s physical boundary is drawn at the casing of the tested operational platform (Zebra ZQ521 printer). The physical components that comprise the module are production grade. All ICs are coated with industry standard passivation.
8. Non-Invasive Security The module does not claim any non-invasive security.
9. Sensitive Security Parameters Management The following table summarizes the keys and Sensitive Security Parameters (SSPs) that are used by the cryptographic services implemented in the module. Table 8 – SSPs Zebra Technologies Public Material – May be reproduced only in its original entirety (without revision).

10. Self-Tests When the module is loaded or instantiated (after being powered off, rebooted, etc.), the module runs pre-operational self-tests. The operating system is responsible for the initialization process and loading of the library. The module is designed with a default entry point (DEP) which ensures that the self-tests are initiated automatically when the module is loaded. Prior to the module providing any data output via the data output interface, the module performs and passes the pre-operational self-tests. Following the successful pre-operational self-tests, the module executes the Conditional Cryptographic Algorithm Selftests (CASTs). The self-test success or failure results are an output of the return value of the library load API call, which is functioning as the self-test status indicator. If any one of the self-tests fails, the module transitions into an error state and outputs the error message via the module’s status output interface. While the module is in the error state, all data through the data output interface and all cryptographic operations are disabled. The error state can only be cleared by reloading the module. All self-tests must be completed successfully before the module transitions to the operational state. Below are the details of the self-tests conducted by the module.
11. Pre-Operational Self-Tests: • Pre-operational Firmware Integrity Test o HMAC-SHA-1 KAT o SHA-1 KAT o Firmware Integrity Test (HMA-SHA-1)
12. Conditional Self-Test: • Conditional Cryptographic Algorithm Self-Tests (CASTs) o AES-ECB 128 bits Encrypt KAT o AES-ECB 128 bits Decrypt KAT o AES-CCM 128 bits Authenticated Encrypt KAT o AES-CCM 128 bits Authenticated Decrypt KAT o HMAC-SHA-1 KAT o SHA-1 KAT
13. Life-Cycle Assurance Secure Operation The validated firmware binary files, including the Zebra 8887 FIPS driver firmware binary file: devnpmv8887-fips.so, and the NXP firmware binary file: sd8887_uapsta.bin, were loaded/installed into the module while being manufactured, and cannot be updated by the operator. The module is enabled by default (and hence used automatically) as part of the device without any user configuration. The module always runs in the Approved Mode of Operation and does not implement any Non-Approved Security Functions. When the module is instantiated (after being powered off, rebooted, etc.), the module runs pre-operational self-tests without any operator intervention. The Module will be operated in an approved mode of operation when pre-operational self-tests have completed successfully. The module is provided directly to solution developers and is not intended for direct download by the general public.

The module supports a Crypto Officer role only. The module provides no authentication. When the module has not been placed in a valid role, the operator shall not have access to any cryptographic services. The operator shall be capable of commanding the module to perform the power up self-tests by cycling power or resetting the module. Power-up self-tests do not require any operator action. Data output shall be inhibited during self-tests, zeroization, and error states. Status information does not contain CSPs or sensitive data that if misused could lead to a compromise of the module. There are no restrictions on which keys or CSPs are zeroized by the zeroization service. The module does not support concurrent operators. The module does not support a maintenance interface or role. The module does not support manual key entry. The module does not have any external input/output devices used for entry/output of data. The module does not output plaintext CSPs. The module does not output intermediate key values. 12. Mitigation of Other Attacks The module has not been designed to mitigate any specific attacks outside the scope of FIPS 140-3 requirements.
