A Security Analysis of Voatz, the First Internet Voting Application Used in U.S
The Ballot is Busted Before the Blockchain: A Security Analysis of Voatz, the First Internet Voting Application Used in U.S. Federal Elections∗ Michael A.

Sebastian Jürg Göndör geb. in Duisburg von der Fakultät IV – Elektrotechnik und Informatik der Technischen Universität Berlin zur Erlangung des akademischen Grades Doktor der Ingenieurwissenschaften - Dr.-Ing. - genehmigte Dissertation Promotionsausschuss: Vorsitzender: Prof. Dr. Thomas Magedanz Gutachter: Prof. Dr. Axel Küpper Gutachter: Prof. Dr. Ulrik Schroeder Gutachter: Prof. Dr. Maurizio Marchese Tag der wissenschaftlichen Aussprache: 6. Juni 2018 Berlin 2018 iii A Bill of Rights for Users of the Social Web Authored by Joseph Smarr, Marc Canter, Robert Scoble, and Michael Arrington1 September 4, 2007 Preamble: There are already many who support the ideas laid out in this Bill of Rights, but we are actively seeking to grow the roster of those publicly backing the principles and approaches it outlines. That said, this Bill of Rights is not a document “carved in stone” (or written on paper). It is a blog post, and it is intended to spur conversation and debate, which will naturally lead to tweaks of the language. So, let’s get the dialogue going and get as many of the major stakeholders on board as we can! A Bill of Rights for Users of the Social Web We publicly assert that all users of the social web are entitled to certain fundamental rights, specifically: Ownership of their own personal information, including: • their own profile data • the list of people they are connected to • the activity stream of content they create; • Control of whether and how such personal information is shared with others; and • Freedom to grant persistent access to their personal information to trusted external sites. -

Um dies möglichst effektiv umsetzen zu können, wurde eine Onlinebefragung für Studierende und Beschäftigte der Hochschule Düsseldorf durchgeführt. Diese liefen in zeitlichem Abstand zueinander jeweils 4 Wochen lang. Im Folgenden wird zuerst das methodische Vorgehen zur Befragung kurz erläutert, bevor die Ergeb- nisse vorgestellt werden. Alle Ergebnisse können den Datei-Anhängen „Auswertung_Studie- rende.xlsx“ und „Auswertung_Beschäftigte.xlsx“ entnommen werden. 4 Auswertung Social-Media-Umfrage 2 Methode Damit möglichst viele Studierende aus allen Fachbereichen und die Beschäftigten der Hochschule, unabhängig vom Standort, an der Erhebung teilnehmen konnten, wurde die Befragung als reine On- linebefragung durchgeführt. Aufgrund der Ähnlichkeit in Bezug auf die avisierten Zielgruppen, sowie der inhaltlichen Fragestellung wurde die Befragung in Kooperation mit der Campus IT, dem Daten- schutzbeauftragten und dem Fachbereich Sozial- und Kulturwissenschaften realisiert. Der Fragebogen wurde mithilfe der Software Unipark umgesetzt und über den entsprechenden Uni- park-Server für mehrere Wochen zur Beantwortung verfügbar gehalten. Der Umfang des Fragebo- gens wurde dabei so gewählt, dass eine Bearbeitungsdauer von 10 bis 15 Minuten – inklusive Brie- fing und Debriefing – nicht überschritten wurde. Zur Gewinnung von Teilnehmenden wurden diese über diverse Kanäle angesprochen. Auf der Start- seite des Internetauftritts der HSD wurde beispielsweise eine Meldung von der Pressestelle einge- stellt. -

Peertube Has Worked Twice As Hard to Free Your Videos from Youtube !
PeerTube has worked twice as hard to free your videos from YouTube ! Thanks to your donations, we have been developing a software to free us all from YouTube & Co for a year. Why have we gone much further than the first release, (crowdfunded in the spring of 2018), you might ask? Well, that’s because we sincerely believe in the emancipatory power of PeerTube. This article is a part of « Contributopia’s travel journals ». From October to December of 2019, we will assess our many (donations-founded) actions, which are tax-deductible for French taxpayers. Donate here if you can. La version originale (en Français) de cet article est à lire ici. Federation and instances to avoid creating a new tech giant PeerTube’s aim is to create an emancipatory alternative to centralized platforms a la YouTube. In a centralized service, you sign-up with a single address, and each and every of your actions, videos and data are gathered on a single huge computer. For example, Google’s, that hosts YouTube (to be precise, they are server farms rather than huge computers, but on a symbolic level it is the same thing!). Centralisation, CC-By SA Fédération, CC-By SA LILA LILA PeerTube is a software. It can be installed on a server by anyone possessing the appropriate skills; say, for the sake of argument, Bernadette, College X and karate club Y. This is called an instance, i.e. a PeerTube host. In concrete terms, hosting an instance creates a website (let’s say, BernadetTube.fr, CollegeTube.org or KarateTube.net) on which you can watch videos and sign-up, so you can interact or upload your own content. -

Federated Systems
Federated Systems Jeremy Rubin [email protected] December 9, 2015 Abstract Federation is an amazingly powerful tool in a system designer’s tool belt. This work provides a unifying definition for federated. In abbrevia- tion: a system is federated when there are multiple providers of an iden- tical (or nearly identical), interoperable service. The federated paradigm o↵ers much improved fault tolerance, liberty, and privacy over centralized alternatives. The federated paradigm applies to all sorts of systems, from governmental to web services. However, this paradigm seems to be unsus- tainable, either devolving into centralized systems or being outpaced by them. In this paper, I will delve into multiple examples of federated sys- tems, exploring their successes and failures, as well as delving into what caused the decay of these systems. In reflection, I will also provide sev- eral suggestions on how system developers might harden their use of this paradigm. 1 Contents 1 Introduction: 3 2 Defining Federation: 5 2.1 Governmental Federations . 6 2.2 ComputerScience .......................... 8 2.2.1 Simple Sharded Database . 8 2.2.2 Federated Byzantine Agreement . 8 2.2.3 Federated Cryptography . 9 2.3 FederatedIdentity .......................... 9 2.4 TheDefinition ............................ 10 3 Case Studies 11 3.1 E-Mail................................. 12 3.2 Blog.................................. 14 3.3 XMPP................................. 15 3.4 DNS.................................. 16 3.5 Security Assertion Markup Language . 17 3.6 McDonald’s . 18 3.7 Social Networks . 18 3.7.1 Failures in Centralized Social Networks . 18 3.7.2 Hope in Federation? . 20 4 Conclusion 21 4.1 The Federated System Designer’s Handbook . -

Technology Stack for Decentralized Mobile Services
Technology Stack for Decentralized Mobile Services Matouš Skála Technology Stack for Decentralized Mobile Services by Matouš Skála to obtain the degree of Master of Science at the Delft University of Technology, to be defended publicly on Monday August 31, 2020 at 3:00 PM. Student number: 4893964 Project duration: November 15, 2019 – August 31, 2020 Thesis committee: Dr.ir. J.A. Pouwelse, TU Delft, supervisor Dr. J.S. Rellermeyer, TU Delft Dr. N. Yorke-Smith, TU Delft An electronic version of this thesis is available at http://repository.tudelft.nl/. Preface When I was choosing my thesis topic, I originally came up with an idea of designing a decen- tralized social network. After realizing how ambitious that goal was, I later decided to focus on more fundamental issues first and create a library that would allow for building any de- centralized applications, running purely on an overlay network consisting of smartphones. Rather than reinventing the wheel, I took inspiration from an existing networking library de- veloped at TU Delft over the last decade and created its wire-compatible implementation in Kotlin. Interestingly, in the end, I have even implemented a trivial social network to demon- strate the usage of the library, returning back to the original idea. I would like to thank my supervisor Johan Pouwelse for an endless stream of fresh ideas and valuable feedback, and to PhD students of the Delft Blockchain Lab for numerous coffee meetings and for serving me as a walking documentation of the existing codebase.
