Abstract
A method for associating a password with a secured public/private key pair is disclosed. A user public/private key pair is first established for a user. The user public/private key pair includes a user public key and a user private key. Then, the user public/private key pair is encrypted along with a random password, utilizing a chip public key. Next, a first password is generated by hashing a pass phrase. Finally, the random password is encrypted along with the first password, also utilizing the chip public key. As a result, a user can assess the user private key to perform an authentication function by providing the pass phrase.
