1. Executive Summary
This report describes the certification result drawn by the certification body on the
results of the APE evaluation of Korean National Protection Profile for Electronic
Document Encryption V3.0 (“PP” hereinafter) [1] with reference to the Common Criteria
for Information Technology Security Evaluation (“CC” hereinafter) [2]. It describes the
evaluation result and its soundness and conformity. The authors of the PP [1] are
National Security Research Institute (NSR).
The Target of Evaluation (TOE) in the PP [1] is Electronic Document Encryption
designed to protect important documents managed by the organization based on the
encryption/decryption. Also, the TOE shall provide a variety of security features:
security audit, the user identification and authentication including mutual authentication
between TOE components, security management, the TOE access session
management, and the TSF protection function, etc. These TOE Security Functional
Requirements (SFRs) are outlined in the PP [1].
The evaluation of the PP [1] has been carried out by Korea Security Evaluation
Laboratory Co., Ltd. (KSEL) and completed on 10 Nov 2022. This report grounds on
the evaluation technical report (ETR) KSEL had submitted [6]. The evaluation of the PP
[1] was performed in accordance with the APE (Protection Profile Evaluation)
requirements in CC Part 3 and the Common Methodology for Information Technology
Security Evaluation (“CEM” hereinafter) [3].
The PP [1] does not claim conformance to any other Protection Profile. All Security
Assurance Requirements (SARs) in the PP [1] are based only upon assurance
component in CC Part 3, and the assurance package is EAL1 augmented by
ATE_FUN.1. Therefore the PP [1] is CC Part 3 conformant. The Security Functional
Requirements (SFRs) are based upon both functional components in CC Part 2 and
newly defined components in the Extended component definition chapter of the PP [1].
Therefore the PP [1] is CC Part 2 extended. The PP [1] requires strict conformance.
The operational environment of the Electronic Document Encryption is as shown in
[Figure 1] and [Figure 2].

Certification Validity: The certificate is not an endorsement of the Protection Profile by
ITSCC or by any other organization that recognizes or gives effect to this certificate,
and no warranty of the Protection Profile by ITSCC or by any other organization
recognizes or gives effect to the certificate, is either expressed or implied.

3. Security Policy
The PP [1] has reduced content of a low assurance PP, thus the PP [1] does not have
any explicit security problem definition (i.e., threats, organisational security policies,
and/or assumptions) and security objectives for the TOE. The TOE defined in the PP [1]
provides security features in accordance with the SFRs. Refer to the PP [1] chapter 5
for details.
4. Assumptions and Clarification of Scope
The PP [1] has reduced content of a low assurance PP, thus the PP [1] does not have
any explicit assumptions. The TOE defined in the PP [1] is the Electronic Document
Encryption.
5. Results of the Evaluation
The PP [1] claims EAL1+ (ATE_FUN.1), thus has reduced content of a low assurance
PP.
The evaluation facility provided the evaluation result in the ETR [6] which references a
Single Evaluation Report for APE requirements and Observation Reports. The
evaluation result was based on the CC [2] and CEM [3].
As a result of the evaluation, the verdict PASS is assigned to all assurance
components of APE.
5.1 Protection Profile Evaluation (APE)
The PP Introduction correctly identifies the PP, and the PP reference and the TOE
overview are consistent with each other. Therefore the verdict PASS is assigned to
APE_INT.1.
The Conformance Claim properly describes how the PP conforms to the CC and
packages. Therefore the verdict PASS is assigned to APE_CCL.1.
The Security Objectives for the operational environment from the PP is clearly defined.
Therefore the verdict PASS is assigned to APE_OBJ.1.
Certification Report Page 9
The Extended Components Definition has been clearly and unambiguously defined,
and it is necessary. Therefore the verdict PASS is assigned to APE_ECD.1.
The Security Requirements is defined clearly and unambiguously, and it is internally
consistent. Therefore the verdict PASS is assigned to APE_REQ.1.
Thus, the PP is sound and internally consistent, and suitable to be used as the basis
for writing a low-assurance ST or another low-assurance PP.
The verdict PASS is assigned to the assurance class APE.

6. Recommendations
The PP [1] defines the minimum security requirements for Electronic Document
Encryption, and requires an ST or another PP claiming this PP [1] to fulfill the CC
requirements for strict conformance, but only a low-assurance ST is allowed to make a
conformance to the PP [1]. If the TOE defined in the ST which claims conformance to
the PP [1] implements additional security features, then it is strongly recommended the
ST author to define additional security functional requirements in accordance with the
TOE implementation.
