Available in PDF, EPUB and Kindle. Book excerpt: User authentication and authorization are two of the most critical aspects of computer security and privacy on the web. However, despite their importance, in practice, authentication and authorization are achieved through the use of decade-old techniques that are both often inconvenient for users and have been shown to be insecure against practical attackers. Many approaches have been proposed and attempted to improve and strengthen user authentication and authorization. Among them are authentication schemes that use hardware tokens, graphical passwords, one-time-passcode generators, and many more. Similarly, a number of approaches have been proposed to change how user authorization is performed. Unfortunately, none of the new approaches have been able to displace the traditional authentication and authorization strategies on the web. Meanwhile, attacks against user authentication and authorization continue to be rampant and are often (due to the lack of progress in practical defenses) successful. This dissertation examines the existing challenges to providing secure, private, and usable user authentication and authorization on the web. We begin by analyzing previous approaches with the goal of fundamentally understanding why and how previous solutions have not been adopted. Second, using this insight, we present three systems, each aiming to improve an aspect of user authentication and authorization on the web. Origin-Bound Certificates provide a deployable and secure building block for user credential transfer on the web. PhoneAuth uses Origin-Bound Certificates in order to allow users to securely authenticate to service providers in the face of strong attackers while maintaining the traditional username/password authentication model. Finally, Allowed Referrer Lists allow developers to easily protect applications against authorization vulnerabilities. We present the design, implementation, and evaluation for each of the three systems, demonstrating the feasibility of our approaches. Together, these works advance the state of the art in practical, usable and secure user authentication and authorization on the web. These systems demonstrate that through deep consideration of fundamental stakeholder values and careful engineering, it is possible to build systems that increase the security of user authentication and authorization without adversely impacting the user and developer experiences, while at the same time being deployable and practical.
Download or read book Secure Usable and Practical Authentication for the Internet of Things written by Kyuin Lee (Ph.D.) and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The explosive growth in the number of connected and Internet-of-Things (IoT) devices (e.g., smart speakers, lights, and thermostats) today calls for more convenient and yet secure ways to establish wireless connection between devices.Unfortunately, current device authentication method between typical IoT devices heavily involves manual human interaction by requiring the user to type in a pin or password to establish credentials between two devices. Considering highly distributed and heterogeneous nature of today's connected environment, this unwieldy authentication process particularly degrades the overall usability of IoT systems, which often causes device users to perform poor security practices such as choosing weak passwords or even reusing them. To overcome this usability challenge that leads to various security vulnerabilities, researchers have devised zero-interaction authentication (ZIA) technique which allow devices to autonomously authenticate with each other through common secret extracted from environmental contexts to prove co-existence of devices. In this dissertation, I present series of works on designing and building novel ZIA techniques for spontaneous authentication of IoT devices based on their deployment environments. More specifically, I first propose two techniques named SyncVibe and ivPair, leveraging readily available accelerometer to sense physical vibration in the ambient environment and authenticate closely located wearable and mobile devices in various portable scenarios. Secondly, I present two authentication techniques named VoltKey and AeroKey, designed to seamlessly and continuously associate indoor IoT devices using ubiquitously observable power line noise and ambient electromagnetic radiation as a secret to authenticate co-located devices in a fully autonomous manner. Specifically tailored towards emerging mobile and resource-constrained IoT devices, the proposed works effectively result in higher overall security and usability than traditional authentication approaches while maintaining high practicality to be directly applicable to today's already deployed devices.In addition, to address generic challenges and limitations that exist in the current state-of-the-art ZIA works, I present a framework to automatically determine proper key reconciliation parameters that provide optimal balance between security and usability.

Download or read book Authentication and Authorization on the Web written by Nigel Chapman and published by . This book was released on 2012-10 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: A short book in the "Web Security Topics" series for Web developers, by the well-known authors Nigel and Jenny Chapman. Web applications manipulate resources in response to requests from users. It is often necessary to determine whether a requested operation should be allowed for the user who sent the request. This process of authorization - that is, deciding whether an application should be allowed to carry.out the operation which a request from a particular user or program calls for - depends on, but is separate from, the process of authentication. Authentication means determining the identity of the user or program sending the request. This is usually done by maintaining user accounts, protected by passwords, and by requiring users to log in. Written for professional and student Web developers, this book provides a clear and practical description of authentication and authorization for Web sites. Secure methods of storing users' account details are described, with special emphasis on the secure storage of passwords. The authors explain different methods of authentication, and techniques for applying authorization to requests from authenticated users. A simple application, written in JavaScript and built on the Express framework, is developed throughout the book to demonstrate the principles. The source code is provided via the companion site websecuritytopics.info. Topics covered include hashing and salting passwords for secure storage, using CAPTCHAs to prevent the creation of bogus accounts, resetting passwords, session-based authentication and attacks against sessions, HTTP authentication, OpenId, authorization based on user accounts, role-based authorization, and OAuth. Notes on relevant topics in cryptography are also included. Clear key points provide useful summaries at the end of each section, and technical terms are defined in a 16-page glossary.
