SERVER, VEHICLE, AND SOFTWARE MANAGEMENT METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240201977 titled 'SERVER, VEHICLE, AND SOFTWARE MANAGEMENT METHOD

Simplified Explanation:

This patent application describes a server system designed to manage software for a vehicle's electronic control unit. The server includes memories to store flag data for activating or deactivating specific functions, and processors to generate electronic signatures for added security.

  • The server manages software for a vehicle's electronic control unit.
  • Memories store flag data for switching specific functions on or off.
  • Processors generate electronic signatures for added security.
  • Electronic signatures are created using hash values calculated from flag data and dummy data.
  • The dummy data is not used for switching functions on or off.

Key Features and Innovation:

  • Management of software for vehicle electronic control units.
  • Secure switching of specific functions using flag data and electronic signatures.
  • Use of hash values for added security.
  • Incorporation of dummy data to enhance electronic signature generation.

Potential Applications:

This technology can be applied in the automotive industry for managing software in electronic control units of vehicles. It can also be utilized in other industries requiring secure function switching mechanisms.

Problems Solved:

This technology addresses the need for secure management of software in vehicle electronic control units. It provides a reliable way to switch specific functions on or off while ensuring data integrity.

Benefits:

  • Enhanced security for managing software in electronic control units.
  • Efficient switching of specific functions with added protection.
  • Improved data integrity through electronic signatures.

Commercial Applications:

Title: Secure Software Management System for Vehicle Electronic Control Units

This technology can be commercially used by automotive manufacturers, software developers, and companies in the transportation industry. It offers a secure solution for managing software in electronic control units, ensuring reliable function switching and data integrity.

Questions about Secure Software Management System for Vehicle Electronic Control Units:

1. How does the system ensure the security of function switching in vehicle electronic control units? 2. What are the potential implications of this technology in the automotive industry?


Original Abstract Submitted

a server is configured to manage software for an electronic control unit mounted on a vehicle. the server includes: one or more memories that store flag data for switching between an activated state and a deactivated state of a specific function that is executable by the software; and one or more processors configured to generate an electronic signature to be added to the flag data. the one or more processors are configured to calculate a hash value from the flag data and dummy data that are not used to switch between the activated state and the deactivated state of the specific function, and generate the electronic signature using the calculated hash value.
