limitations and clarifications of this evaluation.
Certification Report Page 10
Note that:
 This evaluation covers only the specific software version identified in this
document, and not any earlier or later versions released or in process. .(for
the detailed information of TOE version and TOE Components version refer
to the [Table 2])
5. Architectural Information
The architecture of Samsung Smart TV is basically composed based on the ARM
TrustZone technology provided by ARM CPU. The execution environment of Samsung
Smart TV is classified as Trusted Execution Environment(TEE) and Rich OS Application
Environment(REE). TEE functions based on TrustWare V2.0(Operating System Self-
Developed by Samsung Electronics) and Rich OS Application Environment functions in
Tizen 3.0 Operating System. Among the security functions of the TOE, System Integrity
Monitoring function is executed in TEE and REE, whereas Web App Protection function,
Data Encryption/Decryption function, Phishing Site Blocking function, Update Server
Communication function are executed in REE.
5.1 Physical Scope of TOE
The TOE consists of software provided in the form of a library, and developer guidance.
The TOE is distributed to the developers of Samsung Smart TV, and is operated in the
form of a library for its operation after installation. The scope of the TOE includes only
some of the library that is in charge of security function out of all the elements that
compose the whole Samsung Smart TV. That is, the physical scope of TOE includes the
library and the developer guidance of the API provided by the library. The following
security functions are provided in the form of a library by the TOE
Certification Report Page 11
- System Integrity Monitoring
- Web App Protection
- Data Encryption/Decryption
- Phishing Site Blocking
- Update Server Communication
5.2 Logical Scope of TOE
Logical scope of the TOE includes all the aspects that are included in the physical scope
of TOE. That is, all the functions provided by the library are included in the logical scope
of TOE. The following security functions are provided by the TOE
System Integrity Monitoring
The TOE periodically performs the verification on the kernel integrity of Tizen OS while
in normal operation through System Integrity Monitoring function so as to ensure safe
operation of Samsung Smart TV.
System Integrity Monitoring function can be separated into three parts: the part that starts
System Integrity Monitoring function on the application area of Tizen OS; the part that
does system integrity monitoring on the dynamic kernel memory area, while operating
on the kernel module area of Tizen OS, when TOE gets operated; the part that does the
system integrity monitoring on the static area while operating on the application area of
TrustWare.
The System Integrity Monitoring function that operates on application of Tizen OS starts
the monitoring process after being installed in the application area of Tizen OS, and
inserts the part that performs system integrity monitoring on the dynamic kernel memory
area into kernel as a LKM(Loadable Kernel Module) so that the monitoring function can
get operated on the kernel area of Tizen OS.
Certification Report Page 12
As mentioned earlier, the System Integrity Monitoring function that operates on the kernel
module area of Tizen OS performs a part of functions of TOE. Thus, this operates while
being inserted as a LKM(Loadable Kernel Module) by the System Integrity Monitoring
function that operates on the application of Tizen OS. When monitoring function starts,
this performs system integrity monitoring for dynamic kernel memory area.
The System Integrity Monitoring function that operates in the application area of
TrustWare detects whether there is any distortion or not by periodically comparing the
memory value of the static kernel memory and the original value. This also receives the
detected result from the System Integrity Monitoring function that operates on the kernel
module area of Tizen OS, and saves the result along with the result detected in static
kernel memory.
Web App Protection
The TOE provides Web App Protection function in order to prevent execution of an
unauthorized Web App in Samsung Smart TV. Samsung Smart TV can download and
store only the Web App provided in App Store (hereinafter “App Contents Server”)
provided by Samsung Electronics. When registering Web App in App Contents server,
Samsung Electronics registered after encrypting the Web App, and Samsung Smart TV
User can download the Web App from App Contents Server and store it on Samsung
Smart TV. In order to execute the stored Web App, the decryption process is required.
During the decryption process of the Web App, if the Web App is determined to be
modified, the execution of the relevant Web App will be blocked. The TOE uses AES
Algorithm (CTR mode) for decryption of Web App, and the 128-bit sizes of the
cryptographic key.
Data Encryption/Decryption
Certification Report Page 13
The TOE provides encryption/decryption function for important data used in Web App.
The TOE uses AES algorithm (CBC mode) for encryption, and the 256-bit sizes of the
cryptographic key. The cryptographic key is derived from hardware using PBKDF2
algorithm. The Cryptographic key exists on memory after being generated, and is
destroyed after encryption/decryption operation is completed. The zeroization is used as
the cryptographic key destruction method.
Phishing Site Blocking
The TOE provides Phishing Site Blocking function in order to prevent private information
from being exposed to any risks through the access to a harmful phishing site by
Samsung Smart TV User. If Samsung Smart TV User accesses web sites using Web
Browser(Tizen Browser), Phishing Site Blocking function checks the site based on the
phishing site database stored in Smart TV. If the site is suspected for being a phishing
site, Google Safe Browsing service is used to check whether the relevant site is a
phishing site or not. If the relevant site is confirmed to be a phishing site, the information
of such for the site being a phishing site is informed to the user. If the user selects to
block the access to the site, the access to the phishing site is blocked to protect private
information of the user. The TOE also provides Smart TV user the ability to either disable
or enable the Phishing Site Blocking function. If a user disables to use the Phishing Site
Blocking function, the Phishing Site Blocking function is not performed.
The list of Phishing Site on the database is updated periodically through Update Server.
※ When communicating with the TOE and Google Safe Browsing server, the
transmitted data is protected by using TLS protocol provided by the operational
environment.
Update Server Communication
TOE provides the function of updating the database for the list of phishing sites by
Certification Report Page 14
communicating with Update Server. The TOE uses OpenSSL provided in the operational
environment so as to protect transmitted data when communicating with Update server.
6. Documentation
