The goal of the project is the research and development of security features of current information systems. The emphasis is placed on data and communicaton security at both hardware and software levels. The Network Security Research Group and the Applied Numerics and Cryptography Research Group have been involved in research of various security elements and aspects of information systems. It is especially development in the area of cryptanalysis of block and stream ciphers, in network security, in smart-card security, and in reverse engineering. The proposed project also addresses these thematic research areas.

2012

The project aims to research the security of selected IT technologies with emphasis on security and communication of processed data. The research group working at the Department of Computer Systems has been long engaged in research particularly in the areas of truly random number generators, smart card security, network security and reverse engineering. The topics of the proposed project are related to these areas.

2012 - 2014

Our intention is to study the properties of the multiple-modulus residual arithmetic with respect to specific numerical problems of linear algebra. One of complex problems of linear algebra suitable for our purpose is solving large systems of linear equations. This requires to create a model of a solver for performing experiments. The method of Gauss-Jordan elimination with residual pivoting is chosen as the base of the solver. In order to gain precise knowledge about the arithmetic used in the model, a hardware architecture of the model will be emulated on FPGA. This experimental solution enables us also verify the theoretical prediction about the spatial, temporal and communication complexity of the modeled solver.
