Latest Patents

Kaichuan Chang holds a patent titled "Secure verification of physical unclonable function." 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 PUF verifier generates error-correction code information for the PUF reagent value, ensuring robust error correction capabilities. Upon device hardware reset, the PUF verifier can securely verify PUF operation by generating a PUF key hash digest and comparing it with the PUF reagent value without exposing the PUF key.
