Security Target Introduction This section identifies the Security Target (ST) and Target of Evaluation (TOE) identification, ST conventions, ST conformance claims, and the ST organization. The TOE consists of the Samsung Galaxy Devices on Android 6 provided by Samsung Electronics Co., Ltd.. The TOE is being evaluated as a Mobile Device. The Security Target contains the following additional sections: Conformance Claims (Section 2) Security Objectives (Section 3) Extended Components Definition (Section 4) Security Requirements (Section 5) TOE Summary Specification (Section 6) Acronyms and Terminology AA Assurance Activity CC Common Criteria CCEVS Common Criteria Evaluation and Validation Scheme EAR Entropy Analysis Report GUI Graphical User Interface NFC Near Field Communication PCL Product Compliant List PP Protection Profile SAR Security Assurance Requirement SE Secure Element SFR Security Functional Requirement SOF Strength of Function ST Security Target TEE Trusted Execution Environment (TrustZone) TOE Target of Evaluation U.S. United States VR Validation Report Conventions The following conventions have been applied in this document: Security Functional Requirements – Part 2 of the CC defines the approved set of operations that may be applied to functional requirements: iteration, assignment, selection, and refinement. o Iteration: allows a component to be used more than once with varying operations. In the ST, iteration is indicated by a letter placed at the end of the component. For example FDP_ACC.1(1) and FDP_ACC.1(2) indicate that the ST includes two iterations of the FDP_ACC.1 requirement, (1) and (2). o Assignment: allows the specification of an identified parameter. Assignments are indicated using bold and are surrounded by brackets (e.g., [assignment]). Note that an assignment within a selection would be identified in italics and with embedded bold brackets (e.g., [[selected-assignment]]). o Selection: allows the specification of one or more elements from a list. Selections are indicated using bold italics and are surrounded by brackets (e.g., [selection]). Page 4 of 55 Samsung Electronics Co., Ltd. Samsung Galaxy Devices on Android 6 (MDFPP20) Security

  • “Hey Speaker - Why Should I Use You?”
    “HEY SPEAKER - WHY SHOULD I USE YOU?” Exploring the user acceptance of smart speakers by Jonas Hoffmann and Kasper Thuesen Master’s Thesis Business Administration and Information Systems, E-Business Supervision: Ather Nawaz Date of submission: 17th of September 2018 Character count: 222.376 / 97.7 pages Kasper Thuesen, 107905, [email protected] Jonas Hoffmann, 107594, [email protected] Abstract Voice-assistant powered smart speakers are entering private homes by storm, with the purpose of facilitating everyday tasks and simplifying their users’ lives. At the same time, they bring along an array of new challenges due to their purely voice-based interface and their fixed location inside the heart of consumer homes. Motivated by the soaring success of the technology and backed by literature about technology acceptance and user experience, this research investigates what motivates users to continuously use smart speakers in their daily lives and what makes them stop using them. In addition, it explores the gap between expectation and experience for this technology and analyses its influence on smart speaker usage. The research is carried out in two steps. First, 10 selected users are provided with a smart speaker with the task of using the product over the course of four weeks. Consequently, a focus group and several in-depth interviews are conducted with the participants about their experience. The analysis reveals that Usability, Usefulness and Sociality – each consisting of several sub- components – are the main factors that affect smart speaker usage. This research depicts one of the first user-centered analyses of smart speaker usage and opens a door for future research in the area of smart speakers.
