A new approach towards increased security in cyber-physical systems

In an internet connected world, securing systems and communication represents a priority. Cyber-physical systems are a relatively new paradigm. Their main characteristic is connecting computer systems with the real world and they are designed as a network of interacting elements with physical input and output and not standalone devices. In the present paper we offer a solution for securing an agent-based model for cyber-physical systems by using hierarchical access through a public-key cryptosystem with divided private key and steganography.
