MULTI-FACTOR PHYSICALLY UNCLONABLE FUNCTION KEY, COIN, OR RFID

摘要

The invention relates generally a device that authenticates a user, operator, or object using multiple factors, thus decreasing the likelihood of unauthorized use. These factors preferably are independent from each other and difficult to defeat. By combining a mechanical key with a number of physically unclonable functions (PUF), the resulting system may be impossible to duplicate or defeat. The addition of the PUF can be deployed to mechanical keys or RFID's of different types without reducing the functionality of the first factors operation.
