Abstract
The present invention provides a method for using a tamper-resistant physical unclonable functions (PUF) to generate temporary passwords, encrypt a password manager database for one-way encryption, and authenticate users. Resistive Random-Access Memory (ReRAM) can be exploited as PUFs. On the server side, a ReRAM PUF can be used to change the format of the password manager database. By comparing the resistance values extracted from the ReRAM PUF, a bitstream can be generated which can then be used as a challenge. Furthermore, by utilizing the hash function and the ReRAM PUF, the password manager database's content can be encrypted as a one-way encryption. The resistance values, which are the ReRAM PUF output, are converted to a bitstream and then replace the user ID and password hash in the database.
