On the Security of the Winternitz One-Time Signature Scheme
Abstract. We show that the Winternitz one-time signature scheme is existentially unforgeable under adaptive chosen message attacks when instantiated with a family of pseudo random ...

A Lambda Calculus for Real Analysis
Abstract Stone Duality is a revolutionary theory that works directly with computable continuous functions, without using set theory, infinitary lattice theory or a prior theory o...

Shape deformation with tunable stiffness
The paper presents a 2D or 3D shape deformation method which incorporates global and local stiffness controls. First, a geometric object is embedded into a regular lattice and then...

Range Extension for Weak PRFs; The Good, the Bad, and the Ugly
We investigate a general class of (black-box) constructions for range extension of weak pseudorandom functions: a construction based on m independent functions F1, . . . , Fm is gi...

Grothendieck Bialgebras, Partition Lattices, and Symmetric Functions in Noncommutative Variables
We show that the Grothendieck bialgebra of the semi-tower of partition lattice algebras is isomorphic to the graded dual of the bialgebra of symmetric functions in noncommutative ...
