Discreet crips in a discrete world: spatialities and temporalities of disability

This article explores the relationships that disabled people have with the space surrounding them. Extending Jacques Lévy’s work on various non-Euclidean spatialities, we study the discontinuous and discrete nature of space as inhabited by disabled …

Origami voting: a non-cryptographic approach to transparent ballot verification

Over the past four decades, fear of election manipulation and hacking has spurred the security technology community to propose a variety of voting systems to implement verifiable voting. Most of these rely on hard to understand cryptographic …

Towards an Empirical Cost Model for Mental Password Algorithms

Reliance on technology has diminished our use of mental computation. However, mental computation's inherent privacy features are becoming central to new research on creating more secure and usable passwords than one gets with approaches such as …

Counting authorised paths in constrained control-flow graphs

Our goal in this extended abstract is to investigate a model of computation inspired by control-flow graphs, automata and arithmetic circuits. The objective is to extend the definition of the first to include computing on nodes and edges. We are …

A note on the inflating enclosing ball problem

Our goal in this paper is, given a connected set of balls, to select and inflate one ball to cover the whole set with the minimal radius. More formally, we are given an abstract metric space and a path-connected set of balls with given centres …

Consonant-Vowel-Consonants for Error-Free Code Entry

Codes and passwords are the bane of user experiences: even small mistakes can delay desired activities, causing undue frustration. Work on codes has focused on security instead of people's ability to enter them error-free. Difficulties observed in a …

CIVICS: Changing Incentives for Voters in International Cooperation through Sampling

This work discusses the possibility of developing new institutional frameworks that could be used as a replacement for the current global international political organs (e.g. the U.N.) which have shown their limited effectiveness in tackling …

Comment corriger efficacement les typos dans les mots de passe

Les mots de passe demeurant la principale méthode d'authentification en ligne, les progrès actuels se concentrent sur le lien entre utilisabilité et sécurité, et comment travailler sur la première améliore la deuxième. Dans une récente série de …

Moving to client-sided hashing for online authentication

Experience shows that the best technology is not always adopted. In the security arena no technology has to stand a harder challenge or has higher consequences for changing society by failure than voting technology. Best technology in voting is …

Password typo correction using discrete logarithms

As passwords remain the main online authentication method, focus has shifted from naive entropy to how usability improvements can increase security. Chatterjee et al. recently introduced the first two typo-tolerant password checkers, their second …
