The Internet of Things is a new technology that is being studied at South Ural State University. The concept when several devices are interconnected and can be controlled remotely is popular due to its convenience in modern life. One of the main tasks of specialists dealing with the Internet of Things is to protect data transmitted through a network. The scheme of information transmission, encryption and storage, which surpasses the available analogues in reliability, was proposed by a team of scientists, including SUSU's staff members. The article on the development of a new scheme was published in one of the most prestigious journals in the field of computer science called IEEE Internet of Things Journal.
Smart Devices Need Data Protection
Smart houses, cars and cities are no longer the sign of the future, but rather an indicator of the present. Technologies allow us to make our life more comfortable by ensuring the interaction of several devices of a computing network, sensors and mechanisms. The concept of such a smart space is called the Internet of Things (IoT). Soon, experts say, the number of IoT devices can exceed the number of mobile phones in the world - the convenience of the technology will be appreciated that much.
However, the process of communication between devices leads to high risks of violation of confidentiality, integrity and availability of data. Since they are all transferred from one subject to another via the Web, the information can be intercepted by attackers. For example, a smart electric meter can transmit information about when lights in a house are turned on and off. After analyzing it, it is easy to calculate the time at which the owners are absent, and get into the apartment. Threats can be bigger and more serious, so specialists are working on designing a reliable IoT infrastructure. It should prevent the loss of information, system failure, or data breach - all that is difficult to predict in advance. To achieve this goal, an international team of scientists, which includes the Director of the School of Electronic Engineering and Computer Science at South Ural State University Gleb Radchenko and the Head of the International Laboratory for Problem-Oriented Cloud Computing Environments of the School of Electronic Engineering and Computer Science Andrei Tchernykh, as well as their colleagues from the Russian Academy Sciences, Moscow Institute of Physics and Technology, Tsinghua University, China, and the Centre for Scientific Research and Higher Education in Ensenada, Mexico), proposed their own version of encryption and storage of data from the Internet of Things devices.
The scientists have introduced a storage architecture called WA-MRC-RRNS. The experts suggest that it is unique as several cloud storages are used instead of one. These may belong to different owners, and the proposed encryption method allows to divide the information into independent parts that are downloaded to different clouds.
"Of course, as we witness the large-scale implementation of the Internet of Things system in all spheres of life, the threats can be very extensive. Loss of information, access denial, information leakage, collusion, technical failures, and data security breaches are difficult to predict in advance. Instead of collecting all the data in one “cloud”, we proposed a different encryption scheme. It will allow placing parts of the data in different cloud storages that belong to various owners. Even if some of the data is intercepted, an attacker will not be able to recover the information from a partial data set. If part of the data is completely lost as a result of the failure, such a scheme will allow recovering data from those parts that were sent to other storages," said Gleb Radchenko.

It should be noted that the promising field of the Internet of Things has been studied for several years at SUSU. In 2018, an agreement was signed with Samsung company, the world's leader in information technology and radio electronics, on the opening of the Samsung IoT Academy and a unique training laboratory for studying the Internet of Things technologies at the School of Electronic Engineering and Computer Science.
South Ural State University has achieved significant results in the creation of the Digital Industry. Research using supercomputer simulation in the field of artificial intelligence, processing, storage and mining of Big Data is actively developing at SUSU.
Research in the digital industry is one of three strategic fields for the development of the scientific and educational activities of South Ural State University along with ecology and materials science.
SUSU is a participant of Project 5-100, designed to enhance the competitiveness of Russian universities among the world's leading research and educational centres.
