Abstract

Different countries are creating and improving information systems that increase the efficiency of city management. Their research takes place within the concept of a smart city. The article considers the formation of this concept in the Russian Federation and its evolution abroad. Information systems “smart city” involve the transfer of a significant amount of data, protected by the methods of classical cryptography, through communication lines. The level of development of quantum technologies allowed us to conclude that this method of information security will not be effective in the medium term. Smart city systems have already lost their cryptographic strength for retrospective attacks. The article analyzes data protection options for information system smart city under quantum threat conditions. Based on the classification of city services, the authors propose a differentiated approach to information security, combining post-quantum cryptography and quantum communication technologies. This will allow the optimal use of public resources and create a smart city information system resistant to quantum computer attacks.
