Enhancing the Security of FPGA-SoCs via the Usage of ARM TrustZone and a Hybrid-TPM

Isolated execution is a concept commonly used for increasing the security of a computer system. In the embedded world, ARM TrustZone technology enables this goal and is currently used on mobile devices for applications such as secure payment or biometric authentication. In this work, we investigate the security benefits achievable through the usage of ARM TrustZone on FPGA-SoCs. We first adapt Microsoft’s implementation of a firmware Trusted Platform Module (fTPM) running inside ARM TrustZone for the Zynq UltraScale+ platform. This adaptation consists in integrating hardware accelerators available on the device to fTPM’s implementation and to enhance fTPM with an entropy source derived from on-chip SRAM start-up patterns. With our approach, we transform a software implementation of a TPM into a hybrid hardware/software design that could address some of the security drawbacks of the original implementation while keeping its flexibility. To demonstrate the security gains obtained via the usage of ARM TrustZone and our hybrid-TPM on FPGA-SoCs, we propose a framework that combines them for enabling a secure remote bitstream loading. The approach consists in preventing the insecure usages of a bitstream reconfiguration interface that are made possible by the manufacturer and to integrate the interface inside a Trusted Execution Environment.

Considering the Artifact Ecology when Supporting the Evolution of Practices - Analyzing the Parallel Journeys of Two Teleconsultation Software in a General Hospital

The growing use of teleconsultation, especially since the start of the Covid-19 pandemic, changes physicians' work at the hospital. In this paper, we set out to study how physicians have integrated teleconsultation into their healthcare practices. Moreover, we are interested in how teleconsultation software contributes to developing new medical practices and how the design of teleconsultation software can better support them. Based on 16 months of fieldwork in a general hospital that offers two different teleconsultation software, we have investigated teleconsultation practices through interviews and observations involving ten physicians doing teleconsultation and a telemedicine secretary. Unlike the existing informal remote care by phone, we observe that teleconsultation supports new formal healthcare practices, particularly for patient care management and inter-organizational cooperation. While analyzing the integration of teleconsultation in physicians' practices, we highlight that both pieces of software do not support those practices on equal terms according to their design. We argue that teleconsultation software design can limit the spread of these new healthcare practices and that the artifact ecology of physicians should be considered during the design process.

A Survey on Different Approaches to Automating the Design Phase in the Software Development Life Cycle

Software design is a basic plan of all elements in the software, how they relate to each other in such a way that they meet the user requirements. In software development process, software design phase is an important phase as it gives a plan of what to do and how to do it during the implementation phase. As the technology is evolving and people's needs in the technological field are increasing, the development of software is becoming more complex. To make the development process somewhat easy, it is always better to have a plan which is followed throughout the process. In this way, many problems can be solved in the design phase, for which a number of tools and techniques are present. One is known as Design Patterns. In software engineering, a design pattern is a general solution to commonly occurring problems in software design. A design pattern isn't a finished design that can be transformed directly into code.

Penerapan Aplikasi Berbasis Web Untuk Monitoring Pengobatan Pasien Gangguan Jiwa Pada UPT Puskesmas Pasar Usang

Monitoring pengobatan pasien gangguan jiwa adalah pemantauan yang dilakukan oleh pemegang program kesehatan jiwa terhadap pelaksanaan prosedur pengobatan yang dilakukan oleh pasiennya. Selama ini proses pelaksanaan kegiatan monitoring pengobatan pasien gangguan jiwa pada Unit Pelaksana Teknis (UPT) Puskesmas Pasar Usang, Dinas Kesehatan Kabupaten Padang Pariaman belum berjalan dengan baik karena faktor pengelolaan data pasien yang masih dilakukan secara manual. Hal ini menyebabkan penanggung jawab program kesehatan jiwa kesulitan dalam mencari data pasien gangguan jiwa dan tidak memperoleh informasi tentang jadwal kunjungan berobat pasiennya. Selain itu susahnya mengetahui pasien-pasien yang tidak melakukan proses pengobatan secara teratur ke puskesmas (pasien home visit). Sehingga dapat mengakibatkan semakin tingginya tingkat kekambuhan penyakit pasien gangguan jiwa pada UPT Puskesmas Pasar Usang. Maka salah satu solusi untuk mengatasi permasalahan tersebut adalah dengan membangun dan menerapkan sebuah aplikasi untuk dapat melakukan monitoring pengobatan pasien gangguan jiwa. Metodologi penelitian yang digunakan adalah studi literatur sebagai landasan teori dari data penelitian sebelumnya, pengumpulan data berupa observasi, wawancara dan pengumpulan dokumen. Sementara itu metodologi yang digunakan untuk pengembangan aplikasi adalah Waterfall dengan tahapan requirements definitions, system and software design, implementation, dan system testing. Dengan diterapkannya Aplikasi monitoring pengobatan pasien gangguan jiwa berbasis web ini, maka proses monitoring yang berjalan di puskesmas dapat berjalan lebih baik dari sebelumnya.
