1 Executive Summary
This report documents the assessment of the National Information Assurance Partnership
(NIAP) Validation team of the evaluation of Google Pixel Phones on Android 12.0 solution
provided by Google LLC. It presents the evaluation results, their justifications, and the
conformance results. This Validation Report (VR) is not an endorsement of the Target of
Evaluation (TOE) by any agency of the U.S. government, and no warranty is either expressed
or implied.
The evaluation was performed by the Gossamer Security Solutions (Gossamer) Common
Criteria Testing Laboratory (CCTL) in Columbia, MD, United States of America, and was
completed in February 2022. The information in this report is largely derived from the
Evaluation Technical Report (ETR) and associated test reports, all written by Gossamer
Security Solutions. The evaluation determined that the product is both Common Criteria
Part 2 Extended and Part 3 Extended and meets the assurance requirements of the Protection
Profile For Mobile Device Fundamentals, Version 3.1, 16 June 2017 and the General
Purpose Operating Systems Protection Profile/Mobile Device Fundamentals Protection
Profile Extended Package (EP) Wireless Local Area Network (WLAN) Clients, Version 1.0,
08 February 2016.
The TOE is the Google Pixel Phones on Android 12.0. The TOE identified in this VR has
been evaluated at a NIAP approved CCTL using the Common Methodology for IT Security
Evaluation (Version 3.1, Rev 5) for conformance to the Common Criteria for IT Security
Evaluation (Version 3.1, Rev 5). This VR applies only to the specific version of the TOE as
evaluated. The evaluation has been conducted in accordance with the provisions of the NIAP
Common Criteria Evaluation and Validation Scheme (CCEVS) and the conclusions of the
testing laboratory in the ETR are consistent with the evidence provided.
The Validation team monitored the activities of the Evaluation team, provided guidance on
technical issues and evaluation processes, and reviewed the individual work units and
successive versions of the ETR. The Validation team found that the evaluation showed that
the product satisfies all the functional requirements and assurance requirements stated in the
Security Target (ST). Therefore, the Validation team concludes that the testing laboratory’s
findings are accurate, the conclusions justified, and the conformance results are correct. The
conclusions of the testing laboratory in the ETR are consistent with the evidence produced.
The technical information included in this report was obtained from the Google Pixel Phones
on Android 12.0 Security Target, version 1.0, 2/7/2022 and analysis performed by the
Validation Team.

3 Architectural Information
The TOE is Google Pixel Phones on Android 12.0. The TOE allows basic telephony features
(make and receive phone calls, send and receive SMS/MMS messages) as well as advanced
network connectivity (allowing connections to both 802.11 Wi-Fi and 2G/3G/4G LTE/5G
Google Pixel Phones on Android 12.0 Validation Report Version 1.0, February 28, 2022
3
mobile data networks). The TOE supports using client certificates to connect to access points
offering WPA2/WPA3 networks with 802.1x/EAP-TLS, or alternatively connecting to
cellular base stations when utilizing mobile data.
3.1 TOE Evaluated Platforms
Google manufactures some of the phones in two variants, differing in size (normal and large,
“XL”, or “Pro”) or build materials (entry and premium). The evaluated configuration
consists of the following models and versions:

Google Pixel 3 G013A/B Qualcomm Snapdragon™ 845 4.9
3.2 TOE Architecture
The TOE provides a rich Application Programming Interface (API) to mobile applications
and provides users installing an application the option to either approve or reject an
application based upon the API access that the application requires (or to grant applications
access at runtime).
The TOE also provides users with the ability to protect Data-At-Rest with AES encryption,
including all user and mobile application data stored in the user’s data partition. The TOE
uses a key hierarchy that combines a REK with the user’s password to provide protection to
all user and application cryptographic keys stored in the TOE.
The TOE includes an additional hardware security chip (Titan M) that provides dedicated
key storage (Does not apply to the Pixel 6 Pro and 6). The TOE makes this secure, hardware
key storage available to mobile applications through the StrongBox extensions to Android’s
Keystore. Currently, the StrongBox extension is not used for any system keys but remains
an option for applications to use should they desire the protections it provides.
Finally, the TOE can interact with a Mobile Device Management (MDM) system (not part
of this evaluation) to allow enterprise control of the configuration and operation of the device
so as to ensure adherence to enterprise-wide policies (for example, restricting use of a
corporate provided device’s camera, forced configuration of maximum login attempts,
pulling of audit logs off the TOE, etc.) as well as policies governing enterprise applications
Google Pixel Phones on Android 12.0 Validation Report Version 1.0, February 28, 2022
4
and data (in a an employee-owned device [BYOD] scenario). An MDM is made up of two
parts: the MDM agent and MDM server. The MDM Agent is installed on the phone as an
administrator with elevated permissions (allowing it to change the relevant settings on the
phone) while the MDM Server is used to issue the commands to the MDM Agent. Neither
portion of the MDM process is considered part of the TOE, and therefore not being directly
evaluated.
The TOE includes several different levels of execution including (from lowest to highest):
hardware, a Trusted Execution Environment, Android’s bootloader, and Android’s user
space, which provides APIs allowing applications to leverage the cryptographic functionality
of the device.
3.3 Physical Boundaries
The TOE’s physical boundary is the physical perimeter of its enclosure. The TOE runs
Android as its software/OS, executing on the Google Tensor or Qualcomm Snapdragon
processors. The TOE does not include the user applications that run on top of the operating
system, but does include controls that limit application behavior. Further, the device provides
support for downloadable MDM agents to be installed to limit or permit different
functionality of the device. There is no built-in MDM agent pre-installed on the device.
The TOE communicates and interacts with 802.11-2012 Access Points and mobile data
networks to establish network connectivity, and through that connectivity interacts with
MDM servers that allow administrative control of the TOE.
4 Security Policy
This section summaries the security functionality of the TOE:
1. Security audit
2. Cryptographic support
3. User data protection
4. Identification and authentication
5. Security management
6. Protection of the TSF
7. TOE access
8. Trusted path/channels
4.1 Security audit
The TOE implements a security log and logcat that are each stored in a circular memory
buffer. An MDM agent can read/fetch the security logs, can retrieve logcat logs, and then
handle appropriately (potentially storing the log to Flash or transmitting its contents to the
MDM server). These log methods meet the logging requirements outlined by FAU_GEN.1
in PP_MD_V3.1.
Google Pixel Phones on Android 12.0 Validation Report Version 1.0, February 28, 2022

4.2 Cryptographic support
The TOE includes multiple cryptographic libraries with ACVP certified algorithms for a
wide range of cryptographic functions including the following: asymmetric key generation
and establishment, symmetric key generation, encryption/decryption, cryptographic hashing
and keyed-hash message authentication. These functions are supported with suitable random
bit generation, key derivation, salt generation, initialization vector generation, secure key
storage, and key and protected data destruction. These primitive cryptographic functions are
used to implement security protocols such as TLS, EAP-TLS, and HTTPS and to encrypt the
media (including the generation and protection of data and key encryption keys) used by the
TOE. Many of these cryptographic functions are also accessible as services to applications
running on the TOE allowing application developers to ensure their application meets the
required criteria to remain compliant to PP_MD_V3.1 standards.
4.3 User data protection
The TOE controls access to system services by hosted applications, including protection of
the Trust Anchor Database. Additionally, the TOE protects user and other sensitive data
using encryption so that even if a device is physically lost, the data remains protected. The
TOE’s evaluated configuration supports Android Enterprise profiles to provide additional
separation between application and application data belonging to the Enterprise profile.
Please see the Admin Guide for additional details regarding how to set up and use Enterprise
profiles.
4.4 Identification and authentication
The TOE supports a number of features related to identification and authentication. From a
user perspective, except for FCC mandated (making phone calls to an emergency number)
or non-sensitive functions (e.g., choosing the keyboard input method or taking screen shots),
a password (i.e., Password Authentication Factor) must be correctly entered to unlock the
TOE. Also, even when unlocked, the TOE requires the user re-enter the password to change
the password. Passwords are obscured when entered so they cannot be read from the TOE's
display and the frequency of entering passwords is limited and when a configured number of
failures occurs, the TOE will be wiped to protect its contents. Passwords can be constructed
using upper and lower cases characters, numbers, and special characters and passwords up
to 16 characters are supported.
The TOE can also serve as an 802.1X supplicant and can both use and validate X.509v3
certificates for EAP-TLS, TLS, and HTTPS exchanges.
4.5 Security management
The TOE provides all the interfaces necessary to manage the security functions identified in
the Security Target as well as other functions commonly found in mobile devices. Many of
the available functions are available to users of the TOE while many are restricted to
administrators operating through a Mobile Device Management solution once the TOE has
Google Pixel Phones on Android 12.0 Validation Report Version 1.0, February 28, 2022
6
been enrolled. Once the TOE has been enrolled and then un-enrolled, it will remove
Enterprise applications and remove MDM policies.
4.6 Protection of the TSF
The TOE implements a number of features to protect itself to ensure the reliability and
integrity of its security features. It protects particularly sensitive data such as cryptographic
keys so that they are not accessible or exportable through the use of the application
processor’s hardware. The TOE disallows all read access to the Root Encryption Key (REK)
and retains all keys derived from the REK within its Trusted Execution Environment (TEE).
Application software can only use keys derived from the REK by reference and receive the
result.
The TOE also provides its own timing mechanism to ensure that reliable time information is
available (e.g., for log accountability). It enforces read, write, and execute memory page
protections, uses address space layout randomization, and stack-based buffer overflow
protections to minimize the potential to exploit application flaws. It also protects itself from
modification by applications as well as to isolate the address spaces of applications from one
another to protect those applications.
The TOE includes functions to perform self-tests and software/firmware integrity checking
so that it might detect when it is failing or may be corrupt. If any self-tests fail, the TOE will
not go into an operational mode. It also includes mechanisms (i.e., verification of the digital
signature of each new image) so that the TOE itself can be updated while ensuring that the
updates will not introduce malicious or other unexpected changes in the TOE. Digital
signature checking also extends to verifying applications prior to their installation as all
applications must have signatures (even if self-signed).
4.7 TOE access
The TOE can be locked, obscuring its display, by the user or after a configured interval of
inactivity. The TOE also has the capability to display an administrator specified (using the
TOE’s MDM API) advisory message (banner) when the user unlocks the TOE for the first
use after reboot.
The TOE is also able to attempt to connect to wireless networks as configured.
4.8 Trusted path/channels
The TOE supports the use of IEEE 802.11-2012, 802.1X, and EAP-TLS and TLS, HTTPS
to secure communications channels between itself and other trusted network devices.
5 Assumptions & Clarification of Scope
5.1 Assumptions
The Security Problem Definition, including the assumptions, may be found in the following
documents:
Google Pixel Phones on Android 12.0 Validation Report Version 1.0, February 28, 2022
7
• Protection Profile For Mobile Device Fundamentals, Version 3.1, 16 June 2017;
• General Purpose Operating Systems Protection Profile/Mobile Device Fundamentals
Protection Profile Extended Package (EP) Wireless Local Area Network (WLAN)
Clients, Version 1.0, 08 February 2016
That information has not been reproduced here and the MDFPP31/WLANCEP10 should be
consulted if there is interest in that material.
5.2 Clarification of scope
The scope of this evaluation was limited to the functionality and assurances covered in the
MDFPP31/WLANCEP10 as described for this TOE in the ST. Other functionality included
in the product was not assessed as part of this evaluation. All other functionality provided by
the devices needs to be assessed separately, and no further conclusions can be drawn about
their effectiveness.
All evaluations (and all products) have limitations, as well as potential misconceptions that
need clarification. This text covers some of the more important limitations and clarifications
of this evaluation. Note that:
• As with any evaluation, this evaluation only shows that the evaluated configuration
meets the security claims made with a certain level of assurance (the assurance
activities specified in the Mobile Device Fundamentals Protection Profile and the
Wireless Local Area Network Clients Extended Package and performed by the
Evaluation team).
• This evaluation covers only the specific device models and software as identified in
this document, and not any earlier or later versions released or in process.
• Apart from the Admin Guide identified in Section 6, additional customer
documentation for the specific Mobile Device models was not included in the scope
of the evaluation and therefore should not be relied upon when configuring or
operating the device as evaluated.
• This evaluation did not specifically search for, nor attempt to exploit, vulnerabilities
that were not “obvious” or vulnerabilities to objectives not claimed in the ST. The
CEM defines an “obvious” vulnerability as one that is easily exploited with a
minimum of understanding of the TOE, technical sophistication, and resources.
• The functionality evaluated is scoped exclusively to the security functional
requirements specified in the MDFPP31/WLANCEP10 and applicable Technical
Decisions. Any additional security related functional capabilities of the TOE were
not covered by this evaluation.
