        However, two centralized identity providers dominate digital identity and access
        management on the web. This is increasingly becoming a privacy problem in times
        of mass surveillance and data mining for targeted advertisement. Existing systems
        for attribute sharing or credential presentation either rely on a trusted third
        party service or require the presentation to be online and synchronous. In this
        paper we propose a concept that allows the user to manage and share his
        attributes asynchronously with a requesting party using a secure, decentralized
        name system},

  abstract = {GNUnet is an alternative network stack for building secure, decentralized and
        privacy-preserving distributed applications. Our goal is to replace the old
        insecure Internet protocol stack. Starting from an application for secure
        publication of files, it has grown to include all kinds of basic protocol
        components and applications towards the creation of a GNU internet. This
        habilitation provides an overview of the GNUnet architecture, including the
        development process, the network architecture and the software architecture. The
        goal of Part 1 is to provide an overview of how the various parts of the project
        work together today, and to then give ideas for future directions. The text is a
        first attempt to provide this kind of synthesis, and in return does not go into
        extensive technical depth on any particular topic. Part 2 then gives selected
        technical details based on eight publications covering many of the core
        components. This is a harsh selection; on the GNUnet website there are more than
        50 published research papers and theses related to GNUnet, providing extensive
        and in-depth documentation. Finally, Part 3 gives an overview of current plans
        and future work},

        variations and analyze their impact on security and privacy. We also consider
        Namecoin, the GNU Name System and RAINS, which are more radical re-designs of
        name systems in that they both radically change the wire protocol and also
        eliminate the existing global consensus on TLDs provided by ICANN. Finally, we
        assess how the different systems stack up with respect to the goal of improving
        security and privacy of name resolution for the future Internet},

        namespaces. Attributes are encrypted using attribute-based encryption (ABE),
        allowing the user to selectively authorize and revoke access of requesting

        decentralised GNU Name System (GNS) in combination with ciphertext-policy ABE
        using type-1 pairings. To show the practicality of our implementation, we carried
        out experimental evaluations of selected implementation aspects including
        attribute resolution performance. Finally, we show that our design can be used as

  abstract = {The Domain Name System (DNS) is vital for access to information on the
        Internet. This makes it a target for attackers whose aim is to suppress free
        access to information. This paper introduces the design and implementation of the
        GNU Name System (GNS), a fully decentralized and censorship-resistant name
        system. GNS provides a privacy-enhancing alternative to DNS which preserves the
        desirable property of memorable names. Due to its design, it can also double as a
        partial replacement of public key infrastructures, such as X.509. The design of
        GNS incorporates the capability to integrate and coexist with DNS. GNS is based
        on the principle of a petname system and builds on ideas from the Simple
        Distributed Security Infrastructure (SDSI), addressing a central issue with the
        decentralized mapping of secure identifiers to memorable names: namely the
        impossibility of providing a global, secure and memorable mapping without a
        trusted authority. GNS uses the transitivity in the SDSI design to replace the
        trusted root with secure delegation of authority, thus making petnames useful to
        other users while operating under a very strong adversary model. In addition to
        describing the GNS design, we also discuss some of the mechanisms that are needed
        to smoothly integrate GNS with existing processes and procedures in Web browsers.
        Specifically, we show how GNS is able to transparently support many assumptions
        that the existing HTTP(S) infrastructure makes about globally unique names},

  abstract = {The GNU Name System (GNS) is a fully decentralized public key infrastructure
        and name system with private information retrieval semantics. It serves a
        holistic approach to interact seamlessly with IoT ecosystems and enables people
        and their smart objects to prove their identity, membership and privileges -
        compatible with existing technologies. In this report we demonstrate how a wide
        range of private authentication and identity management scenarios are addressed
        by GNS in a cost-efficient, usable and secure manner. This simple, secure and
        privacy-friendly authentication method is a significant breakthrough when cyber
        peace, privacy and liability are the priorities for the benefit of a wide range
        of the population. After an introduction to GNS itself, we show how GNS can be
        used to authenticate servers, replacing the Domain Name System (DNS) and X.509
        certificate authorities (CAs) with a more privacy-friendly but equally usable
        protocol which is trustworthy, human-centric and includes group authentication.
        We also built a demonstrator to highlight how GNS can be used in medical
        computing to simplify privacy-sensitive data processing in the Swiss health-care
        system. Combining GNS with attribute-based encryption, we created ReclaimID, a
        robust and reliable OpenID Connect-compatible authorization system. It includes
        simple, secure and privacy-friendly single sign-on to seamlessly share selected
        attributes with Web services, cloud ecosystems. Further, we demonstrate how
        ReclaimID can be used to solve the problem of addressing, authentication and data
        sharing for IoT devices. These applications are just the beginning for GNS; the
        versatility and extensibility of the protocol will lend itself to an even broader
        range of use-cases. GNS is an open standard with a complete free software
        reference implementation created by the GNU project. It can therefore be easily
        audited, adapted, enhanced, tailored, developed and/or integrated, as anyone is
        allowed to use the core protocols and implementations free of charge, and to
        adopt them to their needs under the terms of the GNU Affero General Public

        voting or auction protocols require Byzantine agreement on large sets of
        elements. Implementations proposed in the literature so far have relied on state
        machine replication, and reach agreement on each individual set element in
        sequence. We introduce set-union consensus, a specialization of Byzantine
        consensus that reaches agreement over whole sets. This primitive admits an
        efficient and simple implementation by the composition of Eppstein's set
        reconciliation protocol with Ben-Or's ByzConsensus protocol. A free software
        implementation of this construction is available in GNUnet. Experimental results
        indicate that our approach results in an efficient protocol for very large sets,
        especially in the absence of Byzantine faults. We show the versatility of
        set-union consensus by using it to implement distributed key generation, ballot
        collection and cooperative decryption for an electronic voting protocol
        implemented in GNUnet},

  abstract = {Elections are a vital tool for decision-making in democratic societies. The
        past decade has witnessed a handful of attempts to apply modern technology to the
        election process in order to make it faster and more cost-effective. Most of the
        practical efforts in this area have focused on replacing traditional voting
        booths with electronic terminals, but did not attempt to apply cryptographic
        techniques able to guarantee critical properties of elections such as secrecy of
        ballot and verifiability. While such techniques were extensively researched in
        the past 30 years, practical implementation of cryptographically secure remote
        electronic voting schemes are not readily available. All existing implementation
        we are aware of either exhibit critical security flaws, are proprietary black-box
        systems or require additional physical assumptions such as a preparatory key
        ceremony executed by the election officials. The latter makes such systems
        unusable for purely digital communities. This thesis describes the design and
        implementation of an electronic voting system in GNUnet, a framework for secure
        and decentralized networking. We provide a short survey of voting schemes and
        existing implementations. The voting scheme we implemented makes use of threshold
        cryptography, a technique which requires agreement among a large subset of the
        election officials to execute certain cryptographic operations. Since such
        protocols have applications outside of electronic voting, we describe their
        design and implementation in GNUnet separately},

        GNUnet conversation currently provides poor Quality of Experience under typical
        wide area network conditions and to propose optimization measures. After network
        shaping and the initialization of two isolated GNUnet peers had been automated,
        delay measurements were done. With emulated network characteristics network
        delay, cryptography delays and audio codec delays were measured and transmitted
        speech was recorded. An analysis of the measurement results and a subjective
        assessment of the speech recordings revealed that extreme outliers occur in most
        scenarios and impair QoE. Moreover it was shown that GNUnet conversation
        introduces a large delay that confines the environment in which good QoE is
        possible. In the measurement environment at least 23 ms always ocurred of which
        large parts are were caused by cryptography. It was shown that optimization in
        the cryptography part and other components are possible. Finally the conditions
        for currently reaching good QoE were determined and ideas for further

        value, even if a fraction of the peers is controlled by an adversary. This thesis
        proposes set union consensus, an efficient generalization of Byzantine consensus
        from single elements to sets. This is practically motivated by Secure Multiparty
        Computation protocols such as electronic voting, where a large set of elements
        must be collected and agreed upon. Existing practical implementations of
        Byzantine consensus are typically based on state machine replication and not
        well-suited for agreement on sets, since they must process individual agreements
        on all set elements in sequence. We describe and evaluate our implementation of
        set union consensus in GNUnet, which is based on a composition of Eppstein set
        reconciliation protocol with the simple gradecast consensus prococol described by
        Ben-Or},

  abstract = {As a means of reducing power consumption, hardware devices are capable to
        enter into sleep-states that have low power consumption. Waking up from those
        states in order to return to work is typically a rather energy-intensive
        activity. Some existing applications have non-urgent tasks that currently force
        hardware to wake up needlessly or prevent it from going to sleep. It would be
        better if such non-urgent activities could be scheduled to execute when the
        respective devices are active to maximize the duration of sleep-states. This
        requires cooperation between applications and the kernel in order to determine
        when the execution of a task will not be expensive in terms of power consumption.
        This work presents the design and implementation of Cryogenic, a POSIX-compatible
        API that enables clustering tasks based on the hardware activity state.
        Specifically, Cryogenic's API allows applications to defer their execution until
        other tasks use the device they want to use. As a result, two actions that
        contribute to reduce the device energy consumption are achieved: reduce the
        number of hardware wake-ups and maximize the idle periods. The energy
        measurements enacted at the end of this thesis demonstrate that, for the specific
        setup and conditions present during our experimentation, Cryogenic is capable to
        achieve savings between 1\% and 10\% for a USB WiFi device. Although we ideally
        target mobile platforms, Cryogenic has been developed by means a new Linux module
        that integrates with the existing POSIX event loop system calls. This allows to
        use Cryogenic on many different platforms as long as they use a GNU/Linux
        distribution as the main operating system. An evidence of this can be found in
        this thesis, where we demonstrate the power savings on a single-board computer},

  abstract = {Home routers are always-on low power embedded systems and part of the
        Internet infrastructure. In addition to the basic router functionality, they can
        be used to operate sensitive personal services, such as for private web and email
        servers, secure peer-to-peer networking services like GNUnet and Tor, and
        encrypted network file system services. These services naturally involve
        cryptographic operations with the cleartext keys being stored in RAM. This makes
        router devices possible targets to physical attacks by home intruders. Attacks
        include interception of unprotected data on bus wires, alteration of firmware
        through exposed JTAG headers, or recovery of cryptographic keys through the cold
        boot attack. This thesis presents Panic!, a combination of open hardware design
        and free software to detect physical integrity attacks and to react by securely
        erasing cryptographic keys and other sensitive data from memory. To improve
        auditability and to allow cheap reproduction, the components of Panic! are kept
        simple in terms of conceptual design and lines of code. First, the motivation to
        use home routers for services besides routing and the need to protect their
        physical integrity is discussed. Second, the idea and functionality of the Panic!
        system is introduced and the high-level interactions between its components
        explained. Third, the software components to be run on the router are described.
        Fourth, the requirements of the measurement circuit are declared and a prototype
        is presented. Fifth, some characteristics of pressurized environments are
        discussed and the difficulties for finding adequate containments are explained.

  abstract = {Making communication more resilient is a main focus for modern decentralised
        networks. A current development to increase connectivity between participants and
        to be resilient against service degradation attempts is to support different
        communication protocols, and to switch between these protocols in case
        degradation or censorship are detected. Supporting multiple protocols with
        different properties and having to share resources for communication with
        multiple partners creates new challenges with respect to protocol selection and
        resource allocation to optimally satisfy the applications' requirements for
        communication. This paper presents a novel approach for automatic transport
        selection and resource allocation with a focus on decentralised networks. Our
        goal is to evaluate the communication mechanisms available for each communication
        partner and then allocate resources in line with the requirements of the
        applications. We begin by detailing the overall requirements for an algorithm for
        transport selection and resource allocation, and then compare three different
        solutions using (1) a heuristic, (2) linear optimisation, and (3) machine
        learning. To show the suitability and the specific benefits of each approach, we
        evaluate their performance with respect to usability, scalability and quality of
        the solution found in relation to application requirements},

        for customers and accountability for merchants. It uses an exchange service to
        issue digital coins using blind signatures, and is thus not subject to the
        performance issues that plague Byzantine fault-tolerant consensus-based
        solutions. The focus of this paper is addressing the challenges payment systems
        face in the context of the Web. We discuss how to address Web-specific
        challenges, such as handling bookmarks and sharing of links, as well as
        supporting users that have disabled JavaScript. Web payment systems must also
        navigate various constraints imposed by modern Web browser security architecture,
        such as same-origin policies and the separation between browser extensions and
        Web pages. While our analysis focuses on how Taler operates within the security
        infrastructure provided by the modern Web, the results partially generalize to
        other payment systems. We also include the perspective of merchants, as existing
        systems have often struggled with securing payment information at the merchant's
        side. Here, challenges include avoiding database transactions for customers that
        do not actually go through with the purchase, as well as cleanly separating
        security-critical functions of the payment system from the rest of the Web
        service},
