==METHOD OF UPDATING DEVICE CERTIFICATE AND DEVICE FOR DRIVING THE METHOD - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18458070 titled 'METHOD OF UPDATING DEVICE CERTIFICATE AND DEVICE FOR DRIVING THE METHOD

==Simplified Explanation==

The abstract describes a device with processing circuitry that generates a device identifier and a unique endorsement identity. A first layer sub-circuit receives the device identifier and generates certificates to authenticate the device. The processing circuitry verifies if the device has been modified based on the certificates, and can generate a new endorsement key and certificate signing request if the first layer sub-circuit is modified.

* Device includes processing circuitry for generating device identifier and unique endorsement identity
* First layer sub-circuit generates certificates to authenticate the device based on the identifiers
* Processing circuitry verifies device modifications based on certificates
* First layer sub-circuit can generate new endorsement key and certificate signing request if modified

### Potential Applications
- Secure authentication for devices
- Anti-counterfeiting measures for products
- Ensuring integrity of hardware components

### Problems Solved
- Unauthorized modifications to device components
- Counterfeiting and tampering of products
- Ensuring authenticity and trustworthiness of devices

### Benefits
- Enhanced security for devices
- Protection against counterfeit products
- Reliable authentication and verification process


==Original Abstract Submitted==

A device may include processing circuitry configured to, generate a device identifier associated with the device, and generate a unique endorsement identity (ID) associated with the device identifier, a first layer sub-circuit configured to, receive the device identifier, and generate a first certificate and a second certificate based on the device identifier and the unique endorsement ID, the first certificate and the second certificate including information to authenticate the device, and the processing circuitry is further configured to, receive the first certificate and the second certificate, and verify whether the device has been modified based on the first certificate and the second certificate, wherein, in response to the first layer sub-circuit being modified, the first layer sub-circuit is further configured to, generate an endorsement key based on a new unique endorsement ID, and generate a certificate signing request for the new unique endorsement ID based on the endorsement key.
