SYSTEMS AND METHODS FOR SECURE MAINTENANCE DEVICE FOR CYBER-PHYSICAL SYSTEMS

Abstract:

Systems and methods are disclosed for providing a secure and assured method for updating software of a cyber-physical system (CPS) device, maintaining a CPS device, diagnosing a CPS device, and transferring of CPS data. The method may include authenticating a moment a secure maintenance device (SMD) is connected to a first device before a software-based communication is established, establishing a secure communication channel between the SMD and the first device, authenticating a user of the first device and determining access rights of the user using an identity of the first device; transmitting digitally signed updates from the SMD to the first device; receiving, at the SMD, digitally signed first data from the first device, performing diagnostic and maintenance functions at the first device, and exporting data from the first device to the SMD for mobile transfer to another platform.
