Subject of Research

The project addresses the following related topics: (a) cryptology, (b) information modelling and coding; (d) information security, and (d) certain related applied mathematics. Main intention of this project is to yield novel achievements regarding certain basic techniques for information processing and mainly information security.

The main corresponding research tracks are as follows. Cryptology - Analysis and design of stream ciphers and key management schemes where the particular research activities include: security evaluation of certain stream ciphers, design of advanced stream ciphers; analysis and improvements of broadcast encryption and secure multicasting schemes. Information Modelling and Coding - Modelling and coding of images and speech where the particular research activities include problems related to measuring of the shape properties and different approaches to the shape characterization and classification, as well as to the shape segmentation problems employing a fuzzy approach where it becomes important to develop shape description methods. The information modelling&coding track also includes consideration of certain complex processes for the further information processing. Information Security Applications of cryptology, information modelling&coding and information processing related applied mathematics for security analysis and design of efficient components for information security issues and particularly regarding conditional data access regarding the contents delivery, integrity and authenticity control. Related Applied Mathematics - Information processing related mathematical problems where particular research activities include certain problems of the proof theory, topology and algebra. The above research tracks assume a number of related miscellaneous information processing issues as well. The background for the proposed research activities include more than related 50 international journal class papers of the project team published during last five years which have been cited more than 100 times. Realization of the planed research activities includes continuation of the international scientific collaboration with some of the leading experts from University of Tokyo, University of Hawaii, and University of Exeter.

Importance of the Planed Research

Importance of the proposed project is a direct consequence of the information security importance for information technologies and contemporary information society. It is well known that the addressed topics are related to different on-going international research projects which also illustrate the actuality of this project. The additional motivations for this project were related to the following three issues: (i) to bring together certain related research topic and provide the environment for theirs mutual interaction and mutual stimulations including that problems from one topic could stimulate research directions in the other or the results from one topic could yield a background for solving the problems in the other; and (ii) to keep together researchers who have achieved significant research results during the previous projects cycle, (iii) to stimulate focusing applied mathematics to the hot real world problems and yield benefits to the considered problems via their addressing employing advanced mathematical techniques. It is expected that certain project achievements appear as a background for development of components for the information security systems. Finally, the importance of the proposed research illustrate the established interest for continuation of the international collaboration (joint research activities) with the leading experts from the following institutions: University of Tokyo, University of Hawaii and University of Exeter.
