Research of application of low-resource cryptography algorithms in decentralized environments

Abstract

The purpose of this material is to analysis of the application of low-resource cryptography algorithms for Internet of Things (IoT) systems and the possibility of their implementation in decentralized systems. Over the past few years, the Internet of Things has become one of the most important technologies of the century. Modern IT developments has reached a high level of technological development, which allows you to customize the interaction between IoT devices and provide connection between people. With the appearance of 5G technologies, the IoT has become the center of development, for almost to all modern industries. Devices in this architecture are significantly smaller and have low power consumption. Conventional encryption algorithms tend to be computationally expensive due to their complexity and require many processing rounds. Low-resource cryptography is a compromise between implementation cost, speed, security, performance, and power consumption on IoT devices. The motivation for lightweight cryptography is to use less memory, less computing resources, and less power consumption to provide a security solution that can run on resource-constrained devices. Block ciphers have a fixed length (of bits) and special transformation stages, which are determined by a symmetric key. Block ciphers are quite versatile, which is very useful from an IoT perspective. Another advantage is that block ciphers has nearly proportional encryption and decryption methods. Therefore, it can be implemented with fewer resources.
