This work is motivated by the observation that in DES-like ciphexs it is possible to choose the round functions in such a way that every non-trivial one-round characteristic has sm...
In this paper we present an improvement of the differential attack on hash functions based on block ciphers. By using the specific properties of the collision attack on hash functi...
Abstract. We introduce a generic algorithmic technique and apply it on decision and counting versions of graph coloring. Our approach is based on the following idea: either a graph...
This paper presents the design and implementation of artistic effects in modelling and rendering of volume datasets. Following different stages of a volume-based graphics pipeline...

Abstract. We provide a general framework for constructing identitybased and broadcast encryption systems. In particular, we construct a general encryption system called spatial enc...
