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 …
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 …
—Nine years before Snapchat and its ephemeral messages, Aumann, Ding, and Rabin introduced the idea of everlasting security: an encryption that could not be decrypted after a certain date, no matter the adversary’s computing power. Their method is …
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 …
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 …
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 …
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 …
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 …
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 …
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 …
