INTERNAL CERTIFICATE AUTHORITY FOR ELECTRONIC CONTROL UNIT - A simplified explanation of the abstract

This abstract first appeared for US patent application 17899722 titled 'INTERNAL CERTIFICATE AUTHORITY FOR ELECTRONIC CONTROL UNIT

Simplified Explanation

The abstract describes a method where a first electronic control unit (ECU) provides a fixed private key of a vehicle to a server, generates a limited life certificate based on the fixed private key, and provides the certificate to a second ECU within the vehicle for secure communication with the server.

  • The first ECU acts as a certificate authority in this process.
  • The limited life certificate allows the second ECU to securely communicate with the server.
  • This technology enhances the security of communication between vehicle ECUs and external servers.

Potential Applications

This technology can be applied in the automotive industry for secure communication between vehicle ECUs and external servers, such as for software updates or data exchange.

Problems Solved

1. Ensures secure communication between vehicle ECUs and external servers. 2. Prevents unauthorized access to vehicle systems through secure certificate-based communication.

Benefits

1. Enhanced security for vehicle communication systems. 2. Protection against cyber attacks targeting vehicle ECUs. 3. Improved reliability of software updates and data exchange processes in vehicles.


Original Abstract Submitted

An example operation includes providing by a first electronic control unit (ECU) a fixed private key of a vehicle to a server; generating by the first ECU a limited life certificate based on the fixed private key, wherein the first ECU acts as a certificate authority; and providing the limited life certificate to a second ECU within the vehicle to allow the second ECU to securely communicate with the server.
