Systems and methods for secure maintenance device for cyber-physical systems

A system for securely maintaining, diagnosing, and updating a device while protecting the security assurance of the device, the system comprising:

• a memory storing instructions;
• and
• a processor executing the instructions to perform a process including:
• 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.

A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to perform a method for securely maintaining, diagnosing, and updating a device while protecting the security assurance of the device, the method comprising:

• 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.
