КРИПТОГРАФИЯ: ОТ ПРОШЛОГО К БУДУЩЕМУ

Abstract

The article is devoted to the analysis of modern trends in the development of cryptography, which are related to the issues of cryptography of the past and are reflected in the prospects for the development of cryptography in the future. New trends in the development of cryptography that are relevant in recent decades are highlighted, the main ones of which include: awareness of the mathematical nature of data encryption problems, the rapid increase in the volume of processed and encrypted information that is distributed among a large unlimited circle of users of the modern data transmission devices, practical and theoretical interest of user s in cryptography. It analyzes the continuity of the issues facing cryptography. Among such issues there are: an importance of the human factor in the use of any cryptographic system, the traditional participation of the state in the cryptography development, as well as the theoretical substantiation of ideas of the cryptographic data protection, generalizing the practical experience of using encryption. The author also analyzes the main tasks of cryptography, which include identification, authentication, maintaining the integrity, confidentiality and availability of information during its transfer and storage, emphasizing the need to solve them within the framework of the design and implementation of the complex security systems. Using the development of quantum cryptography as an example, the article emphasizes that the development of new approaches to the cryptographic data protection traditionally leads to the emergence of new vulnerability factors, which means that the traditional issue of cryptography is also to stay ahead of potential attackers.
