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 20240111853 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) based on the device identifier, updating the device's bootloader and certificate based on the CSR using firmware, and authenticating the bootloader update with a certificate from the original equipment manufacturer (OEM) if the initial authentication fails.
- Generating a unique device identifier
- Creating a device identity certificate signing request (CSR)
- Updating the device's bootloader and certificate using firmware
- Authenticating the bootloader update with an OEM certificate
Potential Applications
The technology can be applied in industries where secure device identification and authentication are crucial, such as IoT, cybersecurity, and data protection.
Problems Solved
This technology solves the problem of ensuring the authenticity and security of device identification certificates, especially in cases where the bootloader needs to be updated.
Benefits
The method provides a secure and efficient way to update device identification certificates, enhancing the overall security of the device and protecting against unauthorized access.
Potential Commercial Applications
Potential commercial applications include IoT devices, network security systems, and any industry where secure device identification is essential for operations.
Possible Prior Art
One possible prior art could be the use of digital certificates for device authentication and identification in various industries, but the specific method described in the abstract may be a novel approach to updating certificates through bootloader authentication.
What are the specific steps involved in updating the bootloader and certificate using firmware in this method?
The specific steps involved in updating the bootloader and certificate using firmware include generating a device identifier, creating a certificate signing request based on the identifier, and updating the bootloader with the new certificate using firmware.
How does the authentication process with the OEM certificate work if the initial authentication based on the manufacturer's certificate fails?
If the initial authentication based on the manufacturer's certificate fails, the bootloader update is authenticated using a second certificate from the original equipment manufacturer (OEM) of the device. This additional authentication step ensures the security and integrity of the bootloader update process.
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.
