Abstract

The invention relates to a password protection device which is connected to a host system, the password protection device comprises a password keyboard with numeric keys and an enter key which is used for responding to the operation of a user and generating corresponding digital signal and acknowledge signal. The password protection device further comprises a random number generation unit and a processor, the password keyboard further comprises a display unit, the random number generation unit is used for generating random numbers, the display unit is used for displaying the random numbers, the processor is used for calculating password data according to the random numbers and a digital signal which is input by the user through the numeric keys and sending to the host system for a password validation, so that the input orders of any password on the keyboard are random while the user enters different numeric keys according to the different random numbers on the display unit, thereby effectively prevent password from being peeped. The invention also provides a corresponding password keyboard and a password protection method.
