“…In recent years, this changed as the developments in the space domain have moved towards COTS components [15], [31], open satellite designs [7], [32], and open-source libraries [33]. These factors have been multiplied by the explosive growth in the number of satellites [4] and the inherent increase in the size of the community.…”

Satellites are an essential aspect of our modern society and have contributed significantly to the way we live today, most notable through modern telecommunications, global positioning, and Earth observation. In recent years, and especially in the wake of the New Space Era, the number of satellite deployments has seen explosive growth. Despite its critical importance, little academic research has been conducted on satellite security and, in particular, on the security of onboard firmware. This lack likely stems from by now outdated assumptions on achieving security by obscurity, effectively preventing meaningful research on satellite firmware.In this paper, we first provide a taxonomy of threats against satellite firmware. We then conduct an experimental security analysis of three real-world satellite firmware images. We base our analysis on a set of real-world attacker models and find several security-critical vulnerabilities in all analyzed firmware images. The results of our experimental security assessment show that modern in-orbit satellites suffer from different software security vulnerabilities and often a lack of proper access protection mechanisms. They also underline the need to overcome prevailing but obsolete assumptions. To substantiate our observations, we also performed a survey of 19 professional satellite developers to obtain a comprehensive picture of the satellite security landscape.

“…These academic publications appeared mostly during condensed periods-especially right after the development of ESTCube-1, and we could split them into two areas. First, publications connected with the CubeSat technology (design and flight results), including areas like the main payloads (Iakubivskyi et al, 2020;Lätt et al, 2014); the electrical power system (Pajusalu et al, 2014); or the command and data handling subsystem (CDHS) and its firmware (Laizans et al, 2014;Sünter et al, 2016). Second, publications dealing with the project and the community (knowhow), including a compilation of lessons learnt ; the working processes and the funding (Kalnina et al, 2018); and the management of the community (Noorma et al, 2013;Slavinskis, Reinkubjas, et al, 2015).…”

This article examines a community producing complex space technology. We attempt to highlight which aspects of the community’s activities can help democratize high-tech development while providing a context for similar cases involved in developing and manufacturing nonhigh-technological artefacts. We discuss how this has been made possible by using a technology-determined organizational approach based on the CubeSat open platform infrastructure, blending formal and hands-on education, open communication, specific recruitment and working practices, and a genuine passion for technology. We identify as critical enablers for community-based collaborative development of space technology the open-source architecture standard called CubeSat Design Specifications, the modularization of work in subsystems and between different organizations, and the open and participatory approach work tasks distribution and decision making. Moreover, we argue that the digital/informational aspect of this technology allows the community to implement organizational practices that resemble how open-source movements over the internet produce complex digital artefacts like Wikipedia or Linux. ESTCube can shed light on community-driven complex technology development, providing lessons on what a democratized version of high technology would resemble and how open and digitalized technology can help develop the capacities of a community.

“…Além disso, o TinyOS possui suporte a biblioteca TinySec que fornece autenticação de mensagem, integridade e segurança na semântica de confidencialidade [Bansal and Kumar 2020]. Os microcontroladores do primeiro satélite da Estônia (ESTCube-1) utilizaram o TinyOS no módulo de comunicação do satélite [Sünter et al 2016].…”

The Internet of Things (IoT) is a reality that is already part of our daily lives. In this context, it is essential to understand the fundamentals of prominent protocols, especially at the application layer level, as well as aspects for implementing solutions for IoT. In this document, we introduce the application layer and its protocolos, namely MQTT, CoAP, MQTT-SN, XMPP and DDS. In addition, MQTT and CoAP protocols are presented in practice, as both have been gaining prominence in the literature and the industry, representing two alternatives for the IoT application layer. Finally, potential applications and trends in areas, namely: security, machine learning, computational paradigms, cyberphysical systems and user interfaces are addressed in order to provide insights to readers and encourage them to the development of IoT applications. ResumoA Internet das Coisas, do inglês, Internet of Things (IoT) é uma realidade que já faz parte do nosso cotidiano. Nesse contexto, é fundamental a compreensão dos fundamentos de protocolos proeminentes, especialmente a nível de camada de aplicação, bem como aspectos para a implementação de soluções na IoT. Neste documento, é apresentada a camada de aplicação e seus protocolos MQTT, CoAP, MQTT-SN, XMPP e DDS. Além disso, os protocolos MQTT e CoAP serão apresentados de maneira prática, visto que ambos vem ganhando destaque tanto na literatura quanto na indústria, representando duas alternativas para a camada de aplicação da IoT. Por fim, as potenciais aplicações e tendências nas áreas de segurança, aprendizado máquina, paradigmas computacionais para IoT, sistemas ciber-físicos e interfaces do usuário serão abordadas.
