Abstract
A password system includes a user interface, a password generating unit, and a password checking unit. The password generating unit generates a password including multiple frames, generates an integrity check code associated with the generated password, and scrambles the generated password and provides the scrambled password to the user interface. The password checking unit stores the integrity check code, frame number information and scramble information which are provided from the password generating unit, descrambles a scrambled password that is input from the user interface based on the stored scramble information, and authenticates the user interface by comparing an integrity check code generated from the descrambled password and the stored integrity check code.
