1.1 COMMON CRITERIA CONFORMANCE
The evaluation was conducted using the Common Methodology for Information Technology Security Evaluation,
Version 3.1 Revision 4, for conformance to the Common Criteria for Information Technology Security Evaluation,
Version 3.1 Revision 4.
1.2 TOE DESCRIPTION
The TOE is a Voive Over IP (VoIP) application that executes on a mobile device operating system allowing users
to place secure VoIP calls over data connections. The TOE establishes a secure tunnel, providing confidentiality,
integrity, and data authentication, for voice communications with another SecuSUITE client. This occurs using
the Secure Real-Time Transport Protocol (SRTP) that has been established using the Session Description Protocol
(SDP) and the Security Descriptions for Media Streams for SDP. The TOE also protects communications between
itself and the Secusmart SecuSUITE SIP Server by using a Transport Layer Security (TLS) protected signalling
channel. The TOE also makes use of certificates to authenticate both the SIP server end and the TOE itself
through the TLS connection. The TOE does not work in isolation but relies on SecuSUITE infrastructure
components depicted in Figure 1 below to enable secure VoIP communications.

5 EVALUATION ANALYSIS ACTIVITIES
The evaluation analysis activities involved a structured evaluation of the TOE. Documentation and process
dealing with Development, Guidance Documents, and Life-Cycle Support were evaluated.
5.1 DEVELOPMENT
The evaluators analyzed the TOE functional specification and design documentation; they determined that the
design completely and accurately describes the TOE security functionality (TSF) interfaces, the TSF subsystems
and how the TSF implements the security functional requirements (SFRs). The evaluators analyzed the TOE
security architectural description and determined that the initialization process is secure, that the security
functions are protected against tamper and bypass, and that security domains are maintained. The evaluators
also independently verified that the correspondence mappings between the design documents are correct.
5.2 GUIDANCE DOCUMENTS
The evaluators examined the TOE preparative user guidance and operational user guidance and determined that
it sufficiently and unambiguously describes how to securely transform the TOE into its evaluated configuration
and how to use and administer the product. The evaluators examined and tested the preparative and
operational guidance, and determined that they are complete and sufficiently detailed to result in a secure
configuration.
Section 4.1 provides details on the guidance documents.
5.3 LIFE-CYCLE SUPPORT
An analysis of the TOE configuration management system and associated documentation was performed. The
evaluators found that the TOE configuration items were clearly marked.
The evaluators examined the delivery documentation and determined that it described all of the procedures
required to maintain the integrity of the TOE during distribution to the consumer.
