Title: Innovations of Jun Yu: A Pioneer in Secure Verification Technologies
Introduction
Jun Yu is an accomplished inventor based in Northborough, MA (US), known for his significant contributions to the field of secure verification technologies. With a total of 2 patents, he has developed innovative solutions that enhance the security and reliability of physical unclonable functions (PUFs) and root key provisioning.
Latest Patents
One of Jun Yu's latest patents is focused on the secure verification of physical unclonable functions. This patent describes apparatuses and methods for implementing secure verification of a PUF. The PUF verifier generates a PUF reagent value by obtaining a key from a PUF and a message value useful for PUF verification. The verifier computes a digest value of the PUF key and the message value, selecting a portion of the hash digest as a PUF reagent value. This value is then written to non-volatile memory to enable subsequent verification of the PUF. Additionally, the verifier can generate error-correction code information for the PUF reagent value, ensuring robust verification without exposing the PUF key.
Another notable patent by Jun Yu involves methods and apparatus for secure root key provisioning. This innovation describes techniques for generating a stream of entropy bits based on analog noise. From this stream, entropy symbols are constructed and used to modulate bits of a unique chip identifier, resulting in a block of modulated symbols. A hash digest of this block is calculated to generate a device-level root key, which is securely written to a write-only register of a one-time programmable memory controller. This process prevents unauthorized access to the device-level root key during secure key provisioning.
