Securely Provisioning Secrets in Authentication Devices - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240232361 titled 'Securely Provisioning Secrets in Authentication Devices
The present disclosure aims to enhance the security of root of trust (RoT) chips by preventing malicious provisioning. Unique device secrets (UDS) can only be securely provisioned by trustworthy hardware or firmware, ensuring that entities other than the trustworthy hardware and firmware cannot access a composite device identifier (CDI) generated using the UDS and firmware measurements.
- Prevents malicious provisioning of root of trust (RoT) chips
- Securely provisions unique device secrets (UDS) using trustworthy hardware or firmware
- Ensures that only trustworthy entities can access the composite device identifier (CDI) generated using UDS and firmware measurements
