This article presents optimization results on the recent MOVA undeniable signature scheme presented by Monnerat and Vaudenay at PKC ā04 as well as its generalization proposed at ...
Barrier trees are a convenient way of representing the structure of complex combinatorial landscapes over graphs. Here we generalize the concept of barrier trees to landscapes deļ...
We propose a technique for performing view-dependent geometry and topology simplifications for level-of-detailbased renderings of large models. The algorithm proceeds by preproces...
Abstract. We introduce a new cryptographic problem called time capsule signature. Time capsule signature is a āfuture signatureā that becomes valid from a speciļ¬c future time...
We introduce a new lattice-based cryptographic structure called a bonsai tree, and use it to resolve some important open problems in the area. Applications of bonsai trees include...
