A framework for verifying the integrity of the components of a secure cyber-physical system

Nowadays, a better part of our lives relies on technology. Every day brings new and improved ideas, applications and systems. For this reason, information security has become essential. Integrating both computational and physical components, cyber-physical systems used in more and more situations. Their complexity and the critical nature of the applications in which they are used increases the need for a solid security architecture, built not only to hide information, but to withstand cyber attacks. Our aim has been to find new and improved security architecture for cyber-physical systems. We use hierarchical access to information through the aid of an encryption algorithm with divided private key, combined with steganography. We also add a framework with the goal of verifying the integrity of each component of the system.
