CERTIFICATE UPDATE METHOD AND CERTIFICATE UPDATE SYSTEM OF DEVICE DRIVING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18474702 titled 'CERTIFICATE UPDATE METHOD AND CERTIFICATE UPDATE SYSTEM OF DEVICE DRIVING THE SAME
Simplified Explanation
The method described in the abstract involves updating a certificate for device identification by generating a unique device identifier, creating a device identity certificate signing request (CSR), updating the bootloader, and authenticating the bootloader update using certificates from the original equipment manufacturer (OEM) and the manufacturer of the device.
- Generating a unique device identifier
- Creating a device identity certificate signing request (CSR)
- Updating the bootloader
- Authenticating the bootloader update using certificates from the OEM and the manufacturer
Potential Applications
The technology described in the patent application could be applied in various industries where secure device identification and authentication are crucial, such as IoT devices, automotive systems, and industrial control systems.
Problems Solved
This technology addresses the issue of securely updating device certificates for identification purposes, ensuring that only authorized updates are accepted and preventing unauthorized access to the device.
Benefits

Potential Commercial Applications
The technology could be utilized in industries where secure device authentication is essential, such as in smart home devices, medical equipment, and critical infrastructure systems.
Possible Prior Art
One possible prior art in this field is the use of secure boot mechanisms in devices to ensure the integrity of the bootloader and prevent unauthorized modifications.
What are the specific unique features of this technology compared to existing solutions in the market?
This technology introduces a method of updating device certificates based on a unique device identifier, which adds an extra layer of security and authentication compared to traditional certificate update methods.
How does this technology improve upon existing methods of device identification and authentication?
This technology improves upon existing methods by providing a more secure and reliable way to update device certificates, ensuring that only authorized updates are accepted and authenticated by the device.
Original Abstract Submitted
A method of updating a certificate for device identification of at least one example embodiment includes generating a device identifier comprising unique information of the device, generating a device identity (ID) certificate signing request (CSR) based on the device identifier, updating the bootloader, the updating including updating a certificate of the device based on the device ID CSR using firmware of the device in response to a request of a host device, and in response to the bootloader being changed, authenticating the updating of the bootloader based on a second certificate generated by an original equipment manufacturer (OEM) of the device in response to authentication of the bootloader failing based on a first certificate generated by a manufacturer of the device.
