Decomposability of Polytopes
Abstract. We reformulate a known characterization of decomposability of polytopes in a way which may be more computationally convenient, and offer a more transparent proof. We appl...

Lower Bounds for Non-Black-Box Zero Knowledge
We show new lower bounds and impossibility results for general (possibly non-black-box) zero-knowledge proofs and arguments. Our main results are that, under reasonable complexity...

Type-checking zero-knowledge
This paper presents the first type system for statically analyzing security protocols that are based on zero-knowledge proofs. We show how several properties offered by zero-knowl...
