This paper is devoted to the design and analysis of short undeniable signatures based on a random oracle. Exploiting their online property, we can achieve signatures with a fully s...
Abstract. With computer networks spreading into a variety of new environments, the need to authenticate and secure communication grows. Many of these new environments have particul...
In earlier work, we described a “pathological” example of a signature scheme that is secure in the Random Oracle Model, but for which no secure implementation exists. For that...
