The purpose and objectives of the research: development and analysis of methods, algorithms and cryptoprotection of information on the basis of modular arithmetic during transmission and storage in the info-communication systems and networks.
The following new results have been obtained:
- a model of protected cross-border information exchange has been obtained;
- a model of parties' interaction scheme in the integration system with a protected cross-border information exchange has been offered;
- definitions of the basic concepts of access control based on the quadruple have been proposed: subject area - access control policy - model - access сontrol mechanism. For each of these concepts its semantics has been defined;
- definitions of typed attribute based access control (TABAC) and multi-criteria typed attribute based access control (MTABAC) based on the concept of attribute type have been given. The type is considered as a mathematical object containing definition range of attribute values and the function for the work with its values. The type implemented in the system serves as an access isolation mechanism;
- the followings are defined for TABAC: semantics of subject domain, access control policies, metamodels, models, and access matrix formed by the model;
- for implementation of the access control systems, specification of the logical approach developed in 2015 was proposed. In this regard a multi-level formal model of TABAC and MTABAC has been constructed, which is a system of semantic modeling of TABAC and MTABAC in the form of a metamodel, various security models derived from it and access matrices corresponding to these models;
- model laws and statutory instruments on issues and problems in the field of ICT, namely, protected cross-border exchange;
- the analysis results of known cryptographic algorithms have been obtained;
- the model of digital signature on the basis of non-positional polynomial systems notation (NPSN) has been developed;
- the structural diagram of the EDS model's software implementation has been proposed;
- design of CIPF with a given cryptographic stability on the basis of NPSN with possibility of application in the technology of protected cross-border information exchange;
- structures of databases for storing information, necessary for complete keys (полных ключей ) formation and storage in the national segment of cross-border information exchange has been developed;
- software implementation of the modules making up CIPF.
- The developed method of encryption has been used in the program complex of testing high school graduates in the Republic of Kazakhstan for the first few years to encrypt files with the correct answer codes for recording them on flexible magnetic disks and decoding when reading with errors detection in the testing points. In this respect, access to the decryption procedure has been allowed only in case if all three passwords entered coincided at the stage of file encryption.
- In the law enforcement agencies of the country (NSC, MD, MIA) regarding reliable information security when transferring it through various communication channels, including wireless.
