KASUMI is a block cipher which consists eight Feistel rounds with a 128-bit key. The confidentiality and integrity of UMTS, GSM and GPRS mobile communications systems depend heavi...
An elementary proof of a basic uncertainty principle concerning pairs of representations of ?? vectors in different orthonormal bases is provided. The result, slightly stronger th...
In this work, two new techniques for non-linear feature extraction are presented. In these techniques, new features are obtained as radial projections of the original measurements...
In constraint satisfaction, basic inferences rely on some properties of constraint networks, called consistencies, that allow the identification of inconsistent instantiations (als...
