MOSCOW, 13 Jul. Reliable communication protocol for the smart city network was developed by NCFU scientists in cooperation with Russian and foreign colleagues. According to experts, it will allow devices on the network to quickly, smoothly and securely exchange information and solve the problem of data protection. The results of the study were published in the journal Sensors.
The researchers explained that the concept of a smart city refers to the use of information technology to manage the urban environment. The goal of smart cities is to make the lives of residents more convenient and safer, as well as save resources and space. The simplest example is street lighting, which automatically turns on when there is a shortage of natural light.
A smart city consists of many elements, including video surveillance, emergency call systems, biometric systems, city and banking services, intelligent transport, and much more. It must meet the following requirements: fast connection, reliability and data security.
Scientists from the North Caucasus Federal University (NCFU), in collaboration with colleagues from the Institute for System Programming of the Russian Academy of Sciences, as well as from Mexico, the Republic of Korea and Uruguay, have developed a reliable communication protocol with adaptive multipath routing for the concept of a smart city.
< br />According to them, it increases the resistance of the sensor network to attacks of various types, including unauthorized interception, falsification of messages, errors, failures in the connection of nodes and the network, loss of information in the event of attacks or accidents, etc. And also allows you to optimize resources to create and maintain a smart city.
NCFU specialists explained that the protocol is based on a modification of the MANET (Mobile Ad hoc Networks) network routing. The peculiarity of such a wireless network is that each of its nodes participates in routing by forwarding data for other nodes. him,» Andrey Gladkov, junior researcher at the Educational and Scientific Center for Computational Mathematics and Parallel Programming on a Supercomputer at the NCFU, said.
MANET was originally designed for low-power networks, such as rescue communications, so that people can quickly exchange short messages.
«In our development, we used a system of residual classes, as well as secret sharing schemes, which are based on it,» Gladkov noted.
He explained that when information is encrypted, the key is shared between all devices (participants). In order to recover the key and decrypt the information, it is necessary that all participants provide their parts. If an imaginary attacker intercepts the information, he will not be able to use a single received fragment.
According to the scientists, this approach does not have the limitations inherent in traditional encryption methods for secure transmission of information. In addition, the resulting solution reduces data redundancy, which leads to less use of large-sized equipment, saving energy and message storage volumes.
«The further task of the scientific team is to improve the created protocol, as well as to assemble the network that works with it for further testing «, — Gladkov concluded. html» data->
