Protecting the Management Channel of Robotic Systems

Automated and robotic systems have an indissoluble connection between computing and physical elements included in them. Today, the representatives of such systems can be found in a wide variety of areas – space, automotive, chemical technology, civil infrastructure, energy, health, manufacturing, transportation, and consumer devices. This class of systems is often considered as cyberphysical systems. The article presents an example of creating a robotic complex, as an element of the CBS, with a secure control system based on the AES encryption algorithm, which is currently the most crypto-resistant. In addition, to protect against a brute-force attack on a cryptographic key, the management system must implement a key distribution algorithm to generate a new key each time before executing the command. The article developed a robotic complex and a system that allows you to manage this complex for a reliable cryptographically stable connection. The main element of this system is the STM32F415 cryptographic chip. It allows you to reduce the load on the CPU to perform control algorithms, freeing it from cryptographic operations, thereby ensuring a gain in time.
