Sie sind, vor allem bei der Authenti- fizierung per Passwort, mit spezifischen Nachteilen behaftet, haben andererseits aber auch jeweils besondere Vorteile. Wie solche Kommunikationsstandards und -protokolle wirkungsvoll miteinander kombiniert werden können, um dadurch mehr Sicherheit zu erreichen, haben die Autoren dieser Studie analysiert. Sie spre- chen sich für neuartige Identitätsmanagement-Systeme aus, die sich flexibel auf verschiedene Rollen eines einzelnen Nutzers einstellen können und bequemer zu nutzen sind als bisherige Verfahren. Als ersten Schritt auf dem Weg hin zu einer solchen Identitätsmanagement-Plattform beschreiben sie die Möglichkeiten einer Analyse, die sich auf das individuelle Verhalten eines Nutzers oder einer Sache stützt. Ausgewertet werden dabei Sensordaten mobiler Geräte, welche die Nutzer häu- fig bei sich tragen und umfassend einsetzen, also z.B. internetfähige Mobiltelefone, Fitness-Tracker und Smart Watches. Die Wissenschaftler beschreiben, wie solche Kleincomputer allein z.B. anhand der Analyse von Bewegungsmustern, Positions- und Netzverbindungsdaten kontinuierlich ein „Vertrauens-Niveau“ errechnen kön- nen. Mit diesem ermittelten „Trust Level“ kann jedes Gerät ständig die Wahrschein- lichkeit angeben, mit der sein aktueller Benutzer auch der tatsächliche Besitzer ist, dessen typische Verhaltensmuster es genauestens „kennt“. Wenn der aktuelle Wert des Vertrauens-Niveaus (nicht aber die biometrischen Einzeldaten) an eine externe Instanz wie einen Identitätsprovider übermittelt wird, kann dieser das Trust Level allen Diensten bereitstellen, welche der Anwender nutzt und darüber informieren will. Jeder Dienst ist in der Lage, selbst festzulegen, von welchem Vertrauens-Niveau an er einen Nutzer als authentifiziert ansieht. Erfährt er von einem unter das Limit gesunkenen Trust Level, kann der Identitätsprovider seine Nutzung und die anderer Services verweigern. Die besonderen Vorteile dieses Identitätsmanagement-Ansatzes liegen darin, dass er keine spezifische und teure Hardware benötigt, um spezifische Daten auszuwerten, sondern lediglich Smartphones und so genannte Wearables. Selbst Dinge wie Maschinen, die Daten über ihr eigenes Verhalten per Sensor-Chip ins Internet funken, können einbezogen werden. Die Daten werden kontinuierlich im Hintergrund erhoben, ohne dass sich jemand darum kümmern muss. Sie sind nur für die Berechnung eines Wahrscheinlichkeits-Messwerts von Belang und verlassen niemals das Gerät. Meldet sich ein Internetnutzer bei einem Dienst an, muss er sich nicht zunächst an ein vorher festgelegtes Geheimnis – z.B. ein Passwort – erinnern, sondern braucht nur die Weitergabe seines aktuellen Vertrauens-Wertes mit einem „OK“ freizugeben. Ändert sich das Nutzungsverhalten – etwa durch andere Bewegungen oder an- dere Orte des Einloggens ins Internet als die üblichen – wird dies schnell erkannt. Unbefugten kann dann sofort der Zugang zum Smartphone oder zu Internetdien- sten gesperrt werden. Künftig kann die Auswertung von Verhaltens-Faktoren noch erweitert werden, indem z.B. Routinen an Werktagen, an Wochenenden oder im Urlaub erfasst werden. Der Vergleich mit den live erhobenen Daten zeigt dann 5 an, ob das Verhalten in das übliche Muster passt, der Benutzer also mit höchster Wahrscheinlichkeit auch der ausgewiesene Besitzer des Geräts ist. Über die Techniken des Managements digitaler Identitäten und die damit ver- bundenen Herausforderungen gibt diese Studie einen umfassenden Überblick. Sie beschreibt zunächst, welche Arten von Angriffen es gibt, durch die digitale Identitä- ten gestohlen werden können. Sodann werden die unterschiedlichen Verfahren von Identitätsnachweisen vorgestellt. Schließlich liefert die Studie noch eine zusammen- fassende Übersicht über die 15 wichtigsten Protokolle und technischen Standards für die Kommunikation zwischen den drei beteiligten Akteuren: Service Provi- der/Dienstanbieter, Identitätsprovider und Nutzer. Abschließend wird aktuelle Forschung des Hasso-Plattner-Instituts zum Identitätsmanagement vorgestellt. 6 To prevent the increasing number of identity thefts, more than a douzend technologies are already existing. They have, especially then authentication with passwords, specific disadvantages or advantages, respectively. The authors of this survey analyzed how to combine these communication standards and protocols to provide more security. They recommend new kinds of identity management systems that are flexible for different user roles and are more convenient to use as the existing systems. As a first step to build such an identity management platform the authors describe how to analyze and use the individual behavior of users or objects. As a result sensor data of mobile devices are analyzed. Such devices are internet- ready mobiles, fitness tracker and smart watches. Therefore devices that users often carry with them. The researchers describe how these little computers can continously analyze movement patterns, data of location and connected networks and compute a trust level from the data. With this trust level, a device can indicate the probability that the current user is the actual owner, because it knows the behavioral patterns of the owner. If the current trust level value (not single biometric data) is send to an external entity like an identity provider, this provider can provide the trust level to all services used by the user. Each service is able to decide which trust level value is necessary for user authentication. If the trust level drops under a this specific threshold the identity provider can deny the access to itself and all other services. The particular advantages of this identity management approach is that no special and expensive hardware is needed but instead smartphone and wearables to evaluate the specific data. Even objects like machines that send data of their own behavior to the internet can be used. The data is continously collected in the background so users do not need to care about it. The data is only used for computing the trust level and never leaves the device. If a user logs into an internet service he does not need to remember a secret anymore, e. g. a password, instead he just needs to give an OK to pass on the trust level. If the user behavior is changing, for example by different movement patterns or unknown or new locations when trying to log into a web services, it can be immediately detected and the access to the smartphone or internet services an be locked for the unauthorized person. In future the evaluation can be extended for example with detecting routines on working days, on weekends or on vacations. The comparisons of learned routines with live data will show if the behavior fits into the usual patterns. This survey gives a comprehensive overview of techniques in digital identity management and the related challenges. First, it describes different kinds of attack methods which attacker uses to steal digital identities. Then possible authentication methods are presented. Eventually a summary of the 15 most important protocols and technical standards for communication between the three involved players: ser- vice provider, identity provider and user. Finally, it introduces the current research of the Hasso-Plattner Institute in the area of identity management. 7 Inhaltsverzeichnis 1 Einleitung 11 1.1 Aufbau der Studie . 13 1.2 Digitale Identität . 13 1.3 Ansätze des Identitätsmanagements . 14 1.4 Identitätsmanagement für mehrere Anwendungszwecke . 16 2 Angriffe auf Identitätsdaten 18 3 Methoden der Authentifikation 21 3.1 Authentifizieren durch Wissen . 21 3.2 Authentifizieren durch Besitz . 23 3.3 Authentifizieren durch Biometrie . 24 3.4 Kombinationen der Authentifikations-Methoden . 25 4 Technologien, Protokolle und Standards 27 4.1 Kerberos . 28 4.2 Public-Key

  • Modern Password Security for System Designers What to Consider When Building a Password-Based Authentication System
    Modern password security for system designers What to consider when building a password-based authentication system By Ian Maddox and Kyle Moschetto, Google Cloud Solutions Architects This whitepaper describes and models modern password guidance and recommendations for the designers and engineers who create secure online applications. A related whitepaper, Password security ​ for users, offers guidance for end users. This whitepaper covers the wide range of options to consider ​ when building a password-based authentication system. It also establishes a set of user-focused recommendations for password policies and storage, including the balance of password strength and usability. The technology world has been trying to improve on the password since the early days of computing. Shared-knowledge authentication is problematic because information can fall into the wrong hands or be forgotten. The problem is magnified by systems that don't support real-world secure use cases and by the frequent decision of users to take shortcuts. According to a 2019 Yubico/Ponemon study, 69 percent of respondents admit to sharing passwords with ​ ​ their colleagues to access accounts. More than half of respondents (51 percent) reuse an average of five passwords across their business and personal accounts. Furthermore, two-factor authentication is not widely used, even though it adds protection beyond a username and password. Of the respondents, 67 percent don’t use any form of two-factor authentication in their personal life, and 55 percent don’t use it at work. Password systems often allow, or even encourage, users to use insecure passwords. Systems that allow only single-factor credentials and that implement ineffective security policies add to the problem.

  • Zero-Knowledge User Authentication: an Old Idea Whose Time Has Come
    Zero-Knowledge User Authentication: An Old Idea Whose Time Has Come Laurent Chuat, Sarah Plocher, and Adrian Perrig ETH Zurich Abstract User authentication can rely on various factors (e.g., a pass- word, a cryptographic key, and/or biometric data) but should not re- veal any secret information held by the user. This seemingly paradoxical feat can be achieved through zero-knowledge proofs. Unfortunately, naive password-based approaches still prevail on the web. Multi-factor authen- tication schemes address some of the weaknesses of the traditional login process, but generally have deployability issues or degrade usability even further as they assume users do not possess adequate hardware. This as- sumption no longer holds: smartphones with biometric sensors, cameras, short-range communication capabilities, and unlimited data plans have become ubiquitous. In this paper, we show that, assuming the user has such a device, both security and usability can be drastically improved using an augmented password-authenticated key agreement (PAKE) pro- tocol and message authentication codes. 1 Introduction User authentication still typically involves transmitting a plaintext password to the web server, which is problematic for many reasons. First, an attacker could obtain the user’s password using malware, a keystroke logger, phishing, or a man-in-the-middle attack. Second, the user might be using the same password on different websites, allowing a malicious server operator to impersonate the user. Third, if the website’s database is breached, although passwords may be protected by a hash function, a brute-force attack could reveal low-entropy pass- words. Fourth, as password-reuse and low-entropy passwords are problematic, users are constantly advised to pick new, long, complicated passwords.

  • Lousy Phish— Relay Attacks on Visual Code Authentication Schemes
    I bought a new security token and all I got was this lousy phish| Relay attacks on visual code authentication schemes Graeme Jenkinson, Max Spencer, Chris Warrington, Frank Stajano fgraeme.jenkinson, max.spencer, chris.warrington, [email protected] University of Cambridge Computer Laboratory, Cambridge, UK Abstract. One recent thread of academic and commercial research into web authentication has focused on schemes where users scan a visual code with their smartphone, which is a convenient alternative to password- based login. We find that many schemes in the literature (including, previously, our own) are, unfortunately, vulnerable to relay attacks. We explain the inherent reasons for this vulnerability and offer an architec- tural fix, evaluating its trade-offs and discussing why it has never been proposed by other authors. 1 Introduction We consider a relatively new class of web authentication schemes, currently at- tracting significant academic and commercial interest, which we refer to as visual code authentication schemes. A user may log into a website which supports such an authentication scheme by scanning a visual code, such as a Quick Response (QR) code [1], using their hand-held authenticator device, henceforth scanner. The scanner is generally a smartphone, but might be a dedicated hardware gad- get. The user carries their scanner at all times, or at least whenever they might want to authenticate to a website; the scanner may have a mechanism to prevent its misuse if lost or stolen. Our own Pico system [2] is of course in this class too. Such schemes are interesting because they have some important usability benefits which passwords do not; specifically, there is nothing for users to remem- ber or type1.
