Abstract. Remote electronic voting has attracted increasing attention in cryptographic research. A promising protocol presented by Juels et al. is currently widely discussed. Although it offers a remarkably high degree of coercion-resistance under reasonable assumptions, it can not be employed in practice due to its poor efficiency. The improvements that have been proposed either require stronger trust assumptions or turned out to be insecure. In this paper, we present an enhancement of the protocol, which runs in linear time without changing the underlying trust assumptions.
This paper reviews the challenges associated with the development of tangible and multimodal interfaces and exposes our experiences with the development of three different software architectures to rapidly prototype such interfaces. The article first reviews the state of the art, and further compares existing systems with our approaches. Finally, the article stresses the major issues associated with the development of toolkits allowing the creation of multimodal and tangible interfaces, and presents our future objectives.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
