Московский университет и развитие криптографии в России. Материалы конференции МГУ 17-18 октября 2002 г.
The volume contains proceedings of the XIII International symposium on problems of redundancy in information and control systems.
The volume is to contain the proceedings of the 13th conference AGCT as well as the proceedings of the conference Geocrypt. The conferences focus on various aspects of arithmetic and algebraic geometry, number theory, coding theory and cryptography. The main topics discussed at conferences include the theory of curves over finite fields, theory of abelian varieties both over global and finite fields, theory of zeta-functions and L-functions, asymptotic problems in number theory and algebraic geometry, algorithmic aspects of the theory of curves and abelian varieties, the theory of error-correcting coding and particularly that of algebro-geometric codes, cryptographic issues related to algebraic curves and abelian varieties.
The relevance of scientific research in the field of quantum informatics is grounded. Highlighted promising areas of research. For foreign and Russian publications and materials, an overview of the main scientific results characterizing the current state of quantum informatics has been made. It is concluded that knowledge and resources are most intensively invested in the development of a quantum computer, its architecture and elements, quantum algorithms in the field of cryptography and artificial quantum intelligence. Developments are also actively underway in the field of modeling complex natural and artificial phenomena and processes, the application of quantum computing in the cognitive and social sciences
This proceedings publication is a compilation of selected contributions from the “Third International Conference on the Dynamics of Information Systems” which took place at the University of Florida, Gainesville, February 16–18, 2011. The purpose of this conference was to bring together scientists and engineers from industry, government, and academia in order to exchange new discoveries and results in a broad range of topics relevant to the theory and practice of dynamics of information systems. Dynamics of Information Systems: Mathematical Foundation presents state-of-the art research and is intended for graduate students and researchers interested in some of the most recent discoveries in information theory and dynamical systems. Scientists in other disciplines may also benefit from the applications of new developments to their own area of study.
The first quantum revolution, which determined the development of physics in the 20th century, became the prerequisite for the emergence of nuclear weapons, transistors, lasers, mobile telephony and the Internet. The beginning of the 21st century was the time of the second quantum revolution. Its consequences have not yet fully manifested. Countries capable of creating a quantum computer (a device that can solve tasks that are not available to the most powerful supercomputers of the classical type) will receive a long-term advantage in all areas of competition, including geopolitical dimension.
The concept of an effective attack on a random gamming cipher is formalized; the proof of the existence of such an attack is given; four attacks are constructed with the calculation of their complexity and reliability.
A form for an unbiased estimate of the coefficient of determination of a linear regression model is obtained. It is calculated by using a sample from a multivariate normal distribution. This estimate is proposed as an alternative criterion for a choice of regression factors.
