Captive Portal Network Authentication Based on WebAuthn Security Keys

[Abstract]: Network authentication is performed via different technologies, which have evolved together with authentication systems in other environments. In all these environments, the authentication paradigm during the last decades has been the well known password. However, passwords have some important security problems, like phishing or keylogging. In 2019, the WebAuthn standard from the W3C started a new authentication paradigm based on hardware devices known as security keys. Although they are already being used in many web authentication services, they have not yet been integrated with network authentication mechanisms. This work successfully developed and integrated an authentication server based on WebAuthn security keys with a captive portal system. With this solution, users can be authenticated using security keys within a web-based captive portal network authentication system that gives clients access to network resources. The resulting authentication server is compatible with major operating systems like Windows 10 and Ubuntu 20.04, browsers like Firefox and Google Chrome and security keys like the Solokey and the Yubikey.[Resumo]: A autenticación de rede realízase a través de diferentes tecnoloxías, que evolucionaron xunto con sistemas de autenticación noutros escenarios. En todos estes escenarios, o paradigma de autenticación durante as últimas décadas foi o coñecido contrasinal. Porén, os contrasinais teñen algúns problemas de seguridade importantes, como o phishing ou o keylogging. En 2019, o estándar WebAuthn da W3C comezou un novo paradigma da autenticación baseado en dispositivos físicos coñecidos como chaves de seguridade. Aínda que estas xa se están usando en moitos servizos de autenticación web, aínda non foron integradas en mecanismos de autenticación de rede. Este traballo desenvolveu e integrou con éxito un servidor de autenticación baseado en chaves de seguridade WebAuthn cun sistema de portal cativo. Con esta solución, os usuarios poden autenticarse usando chaves de seguridade nun sistema de autenticación de rede con portal cativo baseado en web que da acceso aos clientes a recursos de rede. O servidor de autenticación resultante é compatible con sistemas operativos relevantes como Windows 10 ou Ubuntu 20.04, navegadores como Firefox e Google Chrome e chaves de seguridade como a Solokey e a Yubikey.Traballo fin de mestrado (UDC.FIC).

Integration of the Captive Portal paradigm with the 802.1X architecture

In a scenario where hotspot wireless networks are increasingly being used, and given the amount of sensitive information exchanged on Internet interactions, there is the need to implement security mechanisms that guarantee data confidentiality and integrity in such networks, as well as the authenticity of the hotspot providers. However, many hotspots today use Captive Portals, which rely on authentication through Web pages (thus, an application-level authentication approach) instead of a link-layer approach. The consequence of this is that there is no security in the wireless link to the hotspot (it has to be provided at upper protocol layers), and is cumbersome to manage wireless access profiles (we need special applications or browsers' add-ons to do that). This work exposes the weaknesses of the Captive Portals' paradigm, which does not follow a unique nor standard approach, and describes a solution that intends to suppress them, based on the 802.1X architecture. This solution uses a new EAP-compliant protocol that is able to integrate an HTTP-based registration or authentication with a Captive Portal within the 802.1X authentication framework

Exon analysis with CAbase : a novel Carbonic Anhydrases database tool.

The Carbonic Anhydrases are a superfamily of proteins, a type of metalloenzyme that are found ubiquitously throughout the most diverse clades in the tree of life. Since first identified as a catalyst for the reversible hydration and dehydration of carbon dioxide almost 90 years ago, the interest in research for its pharmacological and industrial applications is constantly growing and counting with tools like the one here discussed becomes prevailing. When assembly errors or gaps are in exonic regions, misses or misplacing exons occur and it is because of these errors that approaches like homology-based gene models fail due to the lack of correct data. Instead, a similar length of poorly matching sequence may be predicted. Performing exon analysis for the carbonic anhydrases in the context of CAbase aims to identify the mis predicted exons and refers to a set of actions that are possible to perform over them, be they computationally or humanly conducted. Analysis like the comparison of any relevant exon to a desired prototype, the curated addition of labels to them, indicating different important features, or simply, a visual guide to understand their distribution in transcripts or genes of interest. CAbase is a web-based Third Party Annotation System (TPA). A toolkit that allows to browse, annotate and perform analysis over sets of data related to the Carbonic Anhydrases protein family. CAbase is an effort to centralise, normalise and analyse information and annotations over the CA family. To date, 47 CAs (14 Human) genes have been incorporated and currently, more than 50 thousand exons are possible to be characterized based on their splicing site as well as analyse their predicted translations and alignment to the precursor homolog. CAbase continues to be developed, more improvements are included and in conjunction with the usage by the experts in the field of CAs, this inferal type of TPA, could become a central tool in the CA research community, creating better consensus data on this ever-growing protein family

Annual Report of the University, 1999-2000, Volumes 1-4

The Robert O. Anderson School and Graduate School of Management at The University of New Mexico Period of Report: July 1, 1999 to June 30, 2000 Submitted by Howard L. Smith, Dean The Anderson Schools of Management is divided into four distinct divisions- the Department of Accounting; the Department of Finance, International and Technology Management; the Department of Marketing, Information and Decision Sciences; and the Department of Organizational Studies. This structure provides an opportunity for The Anderson Schools to develop four distinct areas of excellence, proven by results reported here. I. Significant Developments During the Academic Year The Anderson Schools of Management • As a result of the multi-year gift from the Ford Motor Company, completed renovation of The Schools\u27 Advisement and Placement Center, as well as all student organization offices. • The Ford gift also provided for $100,000 to support faculty research, case studies and course development. • The Schools revised the MBA curriculum to meet the changing needs of professional, advanced business education. • The Schools updated computer laboratory facilities, with the addition of a 45-unit cluster for teaching and student work. • The faculty and staff of The Schools furthered outreach in economic development activities by participating directly as committee members and leaders in the cluster workgroups of the Next Generation Economy Initiative. • The faculty, staff and students of The Schools contributed to the development of the Ethics in Business Awards; particularly exciting was the fact that all nominee packages were developed by student teams from The Anderson Schools. • The Schools continue to generate more credit hours per faculty member than any other division of the UNM community. The Accounting Department • Preparation and presentation of a progress report to accrediting body, the AACSB. The Department of Finance, International and Technology Management • The Department continued to focus on expansion of the Management of Technology program as a strategic strength of The Schools. The Department of Marketing. Information and Decision Sciences • Generated 9022 credit hours, with a student enrollment of 3070. The Department of Organizational Studies • Coordinated the 9th UNM Universidad de Guanajuato (UG) Mexico Student Exchange
