We present the first efficient group signature scheme that is provably secure without random oracles. We achieve this result by combining provably secure hierarchical signatures i...
Simulating the in-water ocean light field is a daunting task. Ocean waters are one of the richest participating media, where light interacts not only with water molecules, but wit...
Expander2 is a flexible multi-purpose workbench for interactive rewriting, verification, constraint solving, flow graph analysis and other procedures that build up proofs or co...
We show how a polynomial-time prover can commit to an arbitrary finite set Ë of strings so that, later on, he can, for any string Ü, reveal with a proof whether Ü ¾ Ë or Ü ...
Abstract. It has often been claimed that model checking, special purpose automated deduction or interactive theorem proving are needed for formal program development. Recently, it ...
