An Observer-Based Key Agreement Scheme for Remotely Controlled Mobile Robots. (arXiv:2303.04931v1 [eess.SY])

Remotely controlled mobile robots are important examples of Cyber-Physical
Systems (CPSs). Recently, these robots are being deployed in many safety
critical applications. Therefore, ensuring their cyber-security is of paramount
importance. Different control schemes that have been proposed to secure such
systems against sophisticated cyber-attacks require the exchange of secret
messages between their smart actuators and the remote controller. Thus, these
schemes require pre-shared secret keys, or an established Public Key
Infrastructure (PKI) that allows for key agreement. Such cryptographic
approaches …
