Physical unclonable function - Wikipedia
On-chip ECC units increase size, power, and data processing time overheads; they also expose vulnerabilities to power analysis attacks that attempt to model the PUF mathematically. Alternatively, some PUF designs like the EC-PUF do not require an on-chip ECC unit.
PUF | PUFsecurity | PUF-based Security IP Solutions
